Thank you for showing us the inside of a stock 335i exhaust and how well engineered they are. Aftermarket exhaust marketing likes to get us thinking that these things cause a huge bottleneck with aggressive internal bends. We were able to see how the main resonator pipe gave a straight shot to atmosphere and hear how the cross-pipe resonators do a phenomenal job of cancelling out drone, while actually improving flow by allowing pressure peaks from either side to be vented out both tips. I have seen many ads for "performance upgrade" exhaust with wider piping, but always simple muffler design.
You did the wrong part. Your supposed to open up the entire muffler and weld the perforated section, and leave the fiberglass out. How did you miss that most important part.
+Mateo Michel the N55 engines don't include resonators. My e90 came stock with an x pipe. I believe the n54 has the dual cats and and a resonator on the e90.
All I hear from young people these days is DRONE DRONE DRONE. Back in the day, we had big V8's, headers, no cats, no resonators, and true dual exhaust with glasspacks...and no one ever complained about drone. I never even heard the word until about 10 or so years ago. I had to Google it to find out what people were talking about!
Just done this mod. Can't believe I waited so long to get it done. My car sounds awesome!!! Thanks 😊

Did you stuff the insulation back in? I’ve read elsewhere it helps with drone and vibration. Wish I knew more, researching now….!
Which size has the pipe you welded inside the muffler? :)
You need more sounds clips. May be a drive by
Remove stock mufflers, Weld in some race bullets = no drone and sounds great
do you have videos of the exhaust setup you said?
So u don't weld the bottom?
These turbos dont like added back pressure! Fyi. sounds cool !
Did u weld around the pipe or u just welded the top side?
Also interested.?
Hello, could you tell me please pipe diameter? How many mm or cm or inch is it? Thx.
Stack dimes when is comes to welding, keeps the metal from getting super hot but also makes a solid weld aswell.
Would not putting the fiber glass back in make a big difference in the sound or quality?
Could make it drone a tad more and I was trying to avoid that
what is the size for the pipe you used to replace the factory resonator?
do those exhaust tips come off or are the welded on ?
The stock ones are welded to the mufflers
Just get a catless downpipe man that's all you need
its already straight piped so what difference did you make ? lol
drew gil I did the same thing to my car some months ago and it sounds a little louder and cleaner
It was too loud straight piped so I did this to make it more bare-able and look stock because California
You did the wrong part. Your supposed to open up the entire muffler and weld the perforated section, and leave the fiberglass out. How did you miss that most important part.
I replaced the perforated pipes with solid pipes and added the fiberglass back in to avoid any drone.
i think it wouldve made a big difference if you already had catless dp's.
Like.. meaning less drone ?
Any power gain
Hi, how were you able to drop the mufflers off the car? Did you cut it
I cut them off
Tyler England cool, so you welded it back on? Did you have somebody help you on holding it
Yeah I had a muffler shop help with that
Tyler England cool did you need any other parts like an exhaust clamp to reinstall?
Just depends if you weld it back in or clamp it... I welded it and that required nothing new
How did Cruella de Vil's syrup get in there?!?!?!!
What's next on the mod list???
+Ben Singh hmmmm probably some cosmetic things like accent wrap and a spoiler
With the OEM exhaust modded, any drone? And did you not care about welding the bottom at all?
Zero drone for me
I thought the e90's had a resonator and e92 have x pipe?

salut bau boulot ,,,perso je met de la laine d inox ,et peinture HT a chaud après les soudures et une fois reposé a chaud le travail est top merci
Did you have the canflap open or closed?
I have it unplugged so it’s open
Did you put all the packing back in?
About half of it
Sounded good still !
Thanks!
Do you have MHD burble?
Yup!
Is this job possible for a noob welder? Like literally first time of any sorts of welding
I’m a noob welder and it was harder than I expected, mainly because the blade I used to cut it open left a gaping hole
What size pipe did you use
Sorry I can’t seem to remember exactly.. I believe it was 2.5”
What does he mean with "drone"?
At certain speeds and rpm the exhaust will make a low frequency tone that will make you shit your pants. Thinks it’s called the brown note
Hope he didn't ruin that Nomex Shirt lol
Boooiiii goood video
+Ben Singh thanks yo!
9 1/2min video.. 5sec exhaust clip 😒
Nice try bro.
But just go borla with vrsf downpipe.
I’m on the edge for the DP cause California is annoying

OddTimeMan hahaha yeah when I had the mufflers deleted on this car it felt like it was going to vibrate the bolts loose 😂
I dont know in v8's.
But i discover drone when i try to change my golf R exhaust. And now its my most fear. Its horrible
delete resonator
+Alan Ltd the N55 doesn't have any resonators
Lose the sunglasses
Valves
+Madern I have the stock valve unplugged
Never weld again... please lol
aaron lopez your first time welding should be perfect since it requires no skill. Shut up gatekeeper.
chris barber your first time welding you should practice on scrap moron lol
Who hurt you, bud?
chris barber your welds damaged my eyes 😂😂
Stick to video games nerd.
Tu parle trop
