Been modding cars for years (mainly 4 cylinder turbos) and like others have already said in this thread the difference between a catted APR (for example sake) down pipe and a catless APR down pipe when it comes to horsepower is literally 2 or if your lucky 3 HP gain, it’s not noticeable. So in summary it’s not worth the toxic fumes and plus I personally like the exhaust tone better as well...oh and I like passing inspection every year with no issues too.
I always thought if you go catless with full bolts on it would make significant more hp, however if u have minimal bolts on then the difference is barely a 3 4 hp, that's what my tuner told me
@@the_batmobile0.4 it does make significantly more… and the fumes ain’t bad… ya ever smell old converter when someone walks on it? That’s way more nasty that no cat..
I got a catted for my camaro. The catted is a little quieter which for me isn’t bad cause I already have a muffler delete and a careless downpipe for le would be a bit obnoxiously loud. With the catted downpipe I won’t get in cabin fuel smell and pass emissions. All of these factors made me go with catted there was no point in going Catless for me as you would only gain an extra 2 hp at most with a catless and those extra 2 hp aren’t worth considering you’ll smell like gasoline every time you drive your car and having emission inspection problems
My hi-flow catted cts-turbo downipe make about the same hp as a friend catless downpipe. Both mk7 gti, same tune, same condition, same dyno, both stage 2. So unless you're really big turbo pushing 500whp+, the catless hp gain over catted is almost non existent. For anyone that only has a stage 2 or is38, you're good with catted, will save your health and the environment so much more.
@@chriswaseman2562 late but no, High flow will hold up to the pops and bangs tune, as it is less restrictive than factory cat and has bigger cells within the cat which makes it much much much harder to clog the cells.
Just go stage 2, it’ll turn off the CEL. And another difference between catted and catless is the tone. Not everyone wants the rasp sound whereas the catted downpipe keeps a deeper tone in which case having one or the other affects your overall sound from your catback
To whom it may concern; 1. If you remove your cats, you have a good chance of giving yourself cancer. Get a high flow cat. Something to think about if you plan on having kids. How would you feel if you lost a parent? Those that have need not reply, you get it. 2. or B. depending on whether you are numerical or alphabetical, loud four cylinders don't sound all that good. If you need to make noise to be noticed for some reason, get a V8 or above. Also, if you Know your car smells like shit, that means you don't give a shit about other people which makes you an ass hole. Haters... Begin now.
I've got a Mk6 GTI. It came with a hi flow cat and it sounded great but I couldn't pass emissions for some reason so I went stock and I felt the difference immediately. It's been a year! But today I'm going to have my High flow cat reinstalled
Oh and those who think that a cat less is so much more efficient than just going sports cat need to look at dynos and other exhaust testing. A sports cat may even prove to perform better
Mine did this until I replaced the turbo to downpipe gasket. No more leaks and fumes coming through the vents and best of all, no more rasp due to leaks
Depending on your modifications I wouldn’t throw the parts on and run them without a tune, and if you’re running a catted downpipe you shouldn’t get a CEL because you didn’t delete the cat, but you should definitely tune the car with the downpipe being installed
This is for any one need info I got a 2027 gti with a borla exhaust what's a good catted down pipe that will fit the exhaust? Was going to get one on cobb but it fits there exhaust system only i believe .

Hello.. which Downpipe and tune did u select... ??? I have a 2019 GTI with MST intake n AWE track edition the car sounds lovely ... now need more powaaa.... lolz...
Looking to get some nicer sound coming out the back end of my mk7.5 GTI. I don't plan on getting a tune until the warranty is done, and the car is at 10,000KM. Would you suggest just getting a CBE or just a downpipe to start? just specifically for sound. Also, would a DP increase the chance of an engine / turbo problem arising? Don't wanna blow my turbo and then get f*cked on warranty cause of a DP.
My experience from my mk7 is that a CBE is basically a muffler delete or a resonator delete which you can probably do at a shop for way cheaper than buying a whole CBE. Doing one or other alone won’t improve sound much unless 3k RPM. You’d have to do both for a bigger improvement.
I know for my 335 just having a cat less downpipe would let me tune much more than the stock one. Is this true for the gti or is it a less restrictive pipe than the 335?
If I have a aftermarket catted downpipe, let's say Unitronic, will I pass the inspection? I'm in NYC by the way. Or do you know any brand catted pipe that will pass the NYC inspection with a tune, thank you !
Not too sure if it's tuned cause the tune hides and turns off the O2. What you can do is go to a shop you know and have them use an OBD to scan your car first to see if it'll pass or flash back to stock and if the CEL doesn't naturally come on then you'll pass
I’m trying to get a downpipe but I don’t wanna tune bc of my warranty :( could I still run it ? And not hurt anything? Thanks Ik this is a old video but i finally got my gti :)
Forget about the warranty!lol just kidding! Warranty saved me couple times already..for some unexpected shit happened and my car is stockish except for dropsspring..but yeah i just got my intake and inlet pipe and waiting for it to install after couple of yearssss of being bonestock.

Just go IS38 stage 2+ UNI
I like the sound of deep.
Good point yeah that drone is the worst
"The sound of the people" 👌

CTS 3.5 inch catted has been treating me well other than the garbage build quality and it sounding like it leaks all the time.....
Swarley doesn’t sound like it’s treating you well lol

Would you know if I can pass emissions with an APR down pipe if I live in Illinois, Specifically in Chicago.
Lol no unfortunately I wouldn’t know that
Not catless

So should I tune first and then do catted down pipe? What are my chances of CEL with catted?

can you do a muffler delete & resonator delete & also get a downpipe is that bad for your engine?
If you get a catless dp you’re straight piped at that point

Do I need a tune when I get a catless downpipe ?
If you want to take advantage of gaining more hp, yes
I know for my 335 just having a cat less downpipe would let me tune much more than the stock one. Is this true for the gti or is it a less restrictive pipe than the 335?
Yeah, you need an aftermarket dp for stage 2 or higher
So do you need a tune for a catted downpipes. For ny emissions testing
Depends if it throws a CEL or not & if your guy checks visually so it’s all factors to consider
Thank you

Catless.
If u remove the cats will it make the car deeper or more raspier? I have a Mercedes c250 2011 v6 2.5
