    Back in the sixties and seventies we would install our exhaust system without the H pipe initially. Spray some cheap white paint on the exhaust pipes starting 6" behind the collector For an additional 18". Take the vehicle out and drive it for about an hour and put it back on the lift. A short heat discolored area will show up on the pipes. That's where you install your balance tube. Works equally as well without headers. Just spray a longer area. This may sound crude, but it worked quite well. Sometimes you will find that but heat spots are not in the same location on both pipes. Some people would take the average distance and weld the pipe in there. Others would install the balance tube exactly where the heat marks were.

    Placement is key here, old school trick is to draw a line running back along the pipes in crayon, run the engine, where the line stops burning is where you put the crossover. 👍

    • @jaybilis9723

      @slade bonge It was a trick used by Bill 'Grumpy' Jenkins back in the day, aparently he found that the line drawn in crayon stopped burning where the exhaust gasses cooled down and began to expand, he saw HP and TQ gains throughout the rev range when he put a balance pipe at this point in the system, although im sure todays off the shelf systems are designed using the same principles, but might be of help if you are building your own. But dont make the mistake of thinking bigger is better, if you go too big it allows the gasses to expand and cool down faster, this actually creates backpressure, 3in pipe is usually plenty for a street driver. Happy building!

      LiveBig7 only gonna work properly on a vehicle that you can run equal length pipes on.
      The GMT400's have a side mount gas tank, so you can cross in the front, but still have to run the pipes down one side, then split back to have "dual" exhausts.
      But your sound won't be like "true duals" since the pipes are distinctly different lengths.

    It all comes down to what RPM range and throttle opening you drive the most with. If you spend most of your driving time at or near WOT higher RPMS, go for the X-Pipe. If not, go for the H-Pipe. There's a reason the OEMs still use H-Pipes in their exhaust systems even on their higher output engines, and the majority of people will be well served by an H-Pipe over an X-Pipe.

    Engine masters just did a dyno shoot-out comparing straight duals, H-pipe, and X-pipes. They did multiple pulls with each, exhaust size and muffler's were the same for each test. The variance between the three was shy of 4 ft/lbs of tq and 1.5 hp. Maybe NASCAR finds those numbers important, but for the rest of the planet running full exhaust you'll never notice any power difference.
    The real difference is sound, and packaging. The X-pipe sounds best, and is the hardest to fit under the car.

    It’s a great explanation of how exhaust systems work. So many automatically think that larger diameter pipe is better. However, I have seen a number of tests showing that there is little to no scavenging effect after the cats/test pipe area-so an h pipe or x pipe would play little role in that realm

I honestly miss my H pipes I regret removing it. I drive 2002 mustang Roush stage 2 with side exhaust. By the way every engine will sounds different. With new mustang will sound better than mine, 5.0 cayote sound good. mine is 4.6 2v. I will do a cayote swap when this engine goes bad. Future plan. I hope this will help guys. X and H

      @@yaseen123123 I'll be honest it took a long journey to get the exhaust how I wanted it on mine, I started with a rear muffler delete & it droned like crazy. Long story short I ended up with two glasspacks at the rear, a pair of J-pipes to eradicate the drone & I did run it for a while with an H-pipe in place of the resonator. It sounded good but there was still a small amount of drone, so I lost the H-pipe & had a pair of glasspacks put in it's place. It's now perfect for me, no drone & the V8 soundtrack is always there without becoming annoying on long trips. For me no crossover at all sounds best as it gives the true pulsing V8 sound, which Mercedes seemed to do their best to smooth out & eradicate. But it's all down to personal taste, some prefer an X-pipe which gives a more raspy, exotic car sound, some prefer an H-pipe which gives more of an old school V8 sound, I prefer no crossover at all, as for me it should have the signature V8 pulsing, woofly sound. The difference between an X-pipe, H-pipe or even no crossover at all is minimal anyway, there's only a couple of BHP in it.

      This is a fact actually. While I've seen they said many times in reference to motorcycles oh, I agree also with cars and trucks. Especially today when it seems like most people have their heads up their you know what. Half the people are either spaced out of their brains and Clueless, stoned in some type of way, or too busy fumbling with their phones, so they're not paying attention and next thing you know you're in a car accident. But when you're allowed pipes gets them out of their days and they hear you coming you are less likely to be in an accident. Well hopefully anyways.
      I particularly think the whole noise pollution thing in reference to loud pipes is pretty much ridiculous and people need to stop being a bunch of pansies. Of all the things that can be offencive I don't think this is one of them especially when OK it may be a little loud but you can save lives because of it I think the pros outweigh the cons by far.

    There is one other consideration which was not mentioned. Yes, we all want more power, but is there something else we want? Yes! Sound quality....it's one of the reasons so many of us love Ferrari's. They just sound so damn good. I place "X" pipes on all my cars, not just for better performance, but for a noticeable improvement in the exhaust note, with the same mufflers. I learned about this when I was a spectator at Laguna Race Way....I noticed some V8s sounded better than others. After the practice session, I went to the pits and asked the crew why their car sounded so good, compared to the others. They told me they were using an X pipe, vs what the other guys were using: H or Y pipes.

    3:28 Old school rule of thumb is to place the H pipe where the hottest part of the pipe would be if it was just a straight pipe. This applies to fabricators installing an H section into straight pipes. Discoloring of the straight pipe is evident due to overheating and is where the H should be located.

Performance pipes only help on the higher end revs and usually will help only around 70mph and up. . It will actually slow the car off the line a tad bit.

    I put an 3", stainless steel x pipe kit on my 81 Camaro with 511hp. I started it up, and it sounded really bad. Sounded European.
    I immediately dropped the exhaust, cut a slit, and then slid a plate of stainless into the slit and welded it all up. The plate kept each pipe separate.
    WOW WHAT A DEFERANCE! true dual exhaust sound, almost stereo... Beautiful and gurgaly.
    Also, the set of headers used on the dyno weren't that great. I revved it up, and on the deceleration of the engine, it would kinda back fire here and there. Once I got it installed in my car, with equal length, long tube, 1.75" primarys, ceramic coated hooker headers, no more backfires at all. Just pure revs and decelerations. So glorious.

  • @mikemoffett4827

    Plenty of comments from a 40 year vet of the performance exhaust industry! First of all; Exhaust pipe diameter, You are correct about too big can ake exhaust pulses lazy- however; the addition off torque cones into the system , especially on a turbo-equipped car can solve this problem! Just be careful- the pipes get a LOT hotter doing this, so be careful about placement! Secondly; crossover placement or tuning. Optimum placement depends mainly on flow, i.e. cam choice, head flow, etc. An old school , but very effective way to determine where to determine crossover placement is to install a pipe on each bank, spray paint a line on them, and make some passes. where that line burns off (or closest to it as possible) is the best place! Hope this info helps! Doc.

The X pipe has garnered more attention because it's been talked about more. I'd be willing to bet a lot of enthusiasts don't even know what an H pipe is. I prefer more muscle sound instead of rasp. But, again, it's all preference.

    If I recall, when a twin exhaust was installed, it was installed without a H pipe crossover, then draw along the front half of your new exhaust with a high temp crayon, then beat it around for a coupla days. This would burn the crayon at a certain location on each exhaust, determining the points at which your crossover pipe would be installed. Of course you have to consider whether it will fit in the desired location. Been a while. Correct me if I'm wrong.

    Way back in the pre-Internet days, but after Fred Flintstone, I had a 1969 Cutlass with a HO 350, PowerGlide and a Holley 650 double pumper. _STRAIGHT_ 2" pipes out of the headers (insulated) back to a pair of cutouts. One leg of the cutouts went to the mufflers (Hush Thrush's) and the other pointed straight at the ground just behind the rear axle. With the CO's closed it dynoed from 325 - 385 between 2 and 4k RPM. Opening the CO's added about 30HP across that range.

    I;ve found that back then, an H pipe used was a good thing. I put H pipes on a few of my big block Mopars and Pontiacs. I did not curve the pipes but left them straight and put the H in at 30" from the down turn of the exhaust from the manifolds. Used 2 1/2" pipe and Walker Continental glass packs. It sounded great and did pick up the performance a bit. This was done on stock non modified engines. Mopars were stock factory solid flat tap and the Pontiacs were stock factory hyd. flat tap. All of those cars were 4 speeds and road cars not drag cars. Great info video.

      State and local noise laws.. At least on the street. At the race track a uncapped xpipe or header extentions(depending if you have headers) is probably closer. I had a 302 ford years ago and tried an h and x pipe and the x pipe was faster on the drag strip and was a lot quieter around town(2.5 type 40 flowmasters and a 2 .25 dual tailpipe) also removing the 100ish lbs of exhaust and running made 0 difference vrs leaving the full set of x pipes on.

      I understand the X-Pipe would give it a less raspy, higher exhaust note than straight pipe back to the stock mufflers... Would it hurt power much to just go with straight pipes, or H-Pipe replacing the resonator to get that DEEP RASPY sound, or do I need to go with an X-Pipe to keep from losing power on a small, Twin-Turbo V8?

    I have found that on most late model cars & trucks with 2-3 catalytic convertors, the engines need a certain amount of back pressure to run properly due to the restriction of the catalytic convertors. I had a dual X pipe exhaust system installed on my 2017 Chevy Silverado 6.2L LTZ & found out the engine put out less horsepower then the stock exhaust system. That cost me about $4000.00 with TIG welding all connections & moving the 3 catalytic convertors.

    On the other hand, if you happen to enjoy the LOW rumble of a big V8, consider that low frequency sound (i.e. BASS) is slower frequency, as in 4 cylinders at a given RPM versus 8 cylinders at a given RPM. Keeping the two channels of a dual exhaust system maximizes low frequency sound - deep rumble..... Just a thought. If you combine them with a cross over, well, that tends to double the frequency, greatly killing the bass.
    A little something for those of you who consider a big engine sound music to your ears.

    Engine masters tested exhaust wrap on the dyno and it made a whole bunch of nothing for power so the power increase from higher velocity thing is kind of a wives tale, the benefits from wrap is under hood temps potentially affecting heat soak and IAT. The down side is potential increased rust in the wrapped portion of the exhaust reason why most header manufacturers void the warranty if there wrapped. So if your wrapping a s/s header is a good idea at least ceramic coated plus with that and wrap heat would be decreased dramatically which is nice, I've actually noticed through my transparent fuel filter the gasoline boil on a 90°+ day and also the power tanked that day felt like I was riding the brakes. So wrapped exhaust may have stopped that from happening. The kid of weather when pop the hood you are hit with a blast of super hot air like just opened an oven door it's hard to believe an engine will even function at all like that.

  • @NoferTrunions
    @NoferTrunions 4 роки тому +5

    DO NOT wrap your headers all the way to the flange. They will keep the first bend too hot if you do a quality wrap! After a few years on the street, the long side of those bends will basically have turned to slag and will blow out leaving a big round hole. Start wrapping about half way up the side of the engine staying away from the top bend by 4-6 inches.

Huge advertising budgets have been expended by the likes of Borla, Corsa, Billy Boat and Atak on their cat back pipes and mufflers for “performance power and sound.” Each one of these system cost thousands of dollars in parts and labor for what I read maybe only 2-4 hp. I would think that Corvette C7 engineers like Tadge Jeuchter have already engineered near maximum power into the power train. So my question is: can these aftermarket systems possibly be worth their cost? If not, why do many owners gravitate to them nonetheless? Your thoughts are appreciated.

      Wrapped headers were a good .... short term solution to the problem of too much eat in the engine bay... as car became more aerodynamic, the heat became more of a problem.
      Once the aluminum/ceramic - coated headers became widely available at a decent price, there was no good reason to continue using thermal wrapping (especially not on a street-driven car). As many people found out -a winter-driven car, with road salt, snow, rain etc. ... all the moisture would collect inside the wrapping and hold th moister in close contact with tubing headers, exhaust pipes.
      Aluminum/ceramic coated headers ... are much better at resisting heat damage as well as (when coated inside and out) ... they send most of the heat to exit the car... instead of collecting and heat soaking (steaming up) all the moisture.... yes, rusted out headers and exhaust are a big issue when using thermal wrapped exhausts.

    My understanding is that the scavenging effects are not as important on a turbocharged car. My C63s has a valved H - pipe and I think AMG put this there to vary the sound throughout the rev range. I had an issue with the H pipe valve rattling so my exhaust shop welded the valve open all the time. To my shock, the sound of the car has gone backwards quite a bit, especially on overrun. I think AMG must be using the H pipe closed a lot to get a more separated sound out of the turbo V8. With it open all the time, the sound is very noticeably smoother (and quieter) and I don’t like it, it has lost the rorty sound. Very interesting.

    I think it's important to note that not all x pipes are built the same, the ones that come together like the ones shown in the video are typically the best they are called Siamese x pipes because they don't have aggressive Angles of intersection. X pipes that intersect at near 90 degrees have been proven to show flat spots in the power curve when exhaust pulses literally crash into each other and cancel out almost any scavenging and disrupt the gas flow all together. The Siamese style allow for a pass by pull of scavenging vacuum with out having your pulse collide into each other. That's why most weld in x pipes with those angles cause power loses down low where the gas is moving slower and more likely to die off in a collision of pulses. They have less power loss in the Siamese style. I like to think of those as more like a window between both sides where they can pull on each other with vacuum, where as the other is like hallways that intersect and they have to try and pass through each other.

      Question: why not use proper punctuation...? 🥴

      That's what I prefer. Sounds better.

      Because either the H-Pipe OR the X-Pipe gives a performance improvement over the straight, 2-pipe setup.

    H pipe for life , mind you X pipe is good too! if you want a raspy sound vs a low deep tone , like long tube vs short tube headers , what power gain do you want, mid to high or low to mid

    6.6 liter F250 with true dual exhaust. 2.5 to the twin Flowmasters with 3 inch out the side. Plenty of power and sound.

    So how do you achieve scavanging from single pipe exhaust ?
    I have a 96 F150 with 4.9L I was thinking 2-1/4 off manifolds x2 into Y connector into Flowmaster and 3” single out the back ? Stainless of corse. Will this scavange

    My question is for my stock 350 chevy truck with a Y pipe. I want to get more towing torque so what muffler should I use? The catalytic converter is not on the truck anymore. I don't want a loud drone exhaust sound in the cab ..just the better torque numbers.

    96 impala with a LT1. I have true dual exhaust. sounds vicious and has great power. no H or X pipe needed. sounds better too

    I have always been a 1970 Roadrunner fan, but damn that glass pack sound never gets old to hear & sexy to hear.
