Catted pipe is my jam. That kid that keeps running into frame is annoying. Please tell him no one likes him.
-
The 435 sounds much better!! I love the deep tone it has.
-
Guy prancing around like a leprechaun: need some more attention buddy?
-
Both of these sounds pretty damn good!
-
The parking garage under the palisades mall is a great place for exhaust clips. Like being in a tunnel 👍🏻
-
Very informative and well done, it's the only video of its kind!
-
Great video! I appreciate the comparison! Honestly HFC will give a more refined sound, while catless will give you louder and more defined burbles! It’s just a matter of taste in sound IMO.
-
The Catted down pipe sounds good!
-
That RS sounded clean tho
-
In my opinion both are better in eco, more natural. The pops and burbles are nice now and then but if consistent they lose their novelty.
-
Both sound so good
-
Agree the catted pipe sounds loudly deep! im not a raspy sounding exhaust type of person
-
Catted! When dude said the 435 "sounds meatier" that was a perfect description. Can definitely tell exhaust is breathing better and the tone a bit throatier than stock... which for me is perfect, very subtle / fly under the radar. Appreciate you guys sharing... decision made!

When you have straight pipe no cats or so exhaust sound gets a bit raspier. I’d go for high flow cats and resonated tips but that’s just me, both of em are pretty sick whips tho
-
Is there boost creep with the catless downpipe when the weather gets cold?
-
LOVEEEEEEE how the 435 sounds I currently have a 2015 335i F30 and I want this same down pipe, I currently have a Dinan stage 2 tune with an Eventuri intake, I’m considering getting this down pipe and a custom exhaust my question to you is can you link me the website to this downpipe? Another question is did you trigger a CEL? Please help, thank you
-
Does the car with the catless downpipe also have a muffler delete? Or is that with stock Muffler
-
So is catless exhaust mean u can hear the turbo spooling and much louder than catted exhaust?
-
I wanna hear a `09 era N54 catless compared to the N55 with cat
-
New subscriber I think I will go wil the catted downpipe because I don't want any issues with emissions(even tho I currently live in an area that doesn't test for it) also, I'm not of fan of burbles.
