BMW 3-Series N54 Turbo-Back Exhaust is rated 4.7 out of 5 by 22.
Rated 5 out of 5 by from Incomparable quality When shopping for a catback I was torn a few different ways between choosing what brand was right for my taste. After extensive research I went with the Cobb catback for a multitude of reasons - weight savings, V-band, Helmholtz chamber, Y-pipe merging to a single 3" back, Single in dual out muffler, Clamp on tips (so I can move into quad tips if I ever wanted to switch aesthetics), etc. Upon opening the box I was more than excited, as the quality of the product mirrored Cobb's customer support. It was flawless! The quality of the welds, and the finish of the piping/muffler was top notch. After installation I was ecstatic to hear the tone of the exhaust paired with catless downpipes. It's just enough rumble to please the ears without rattling your neighbors windows on cold starts. It's quiet when you want, and throaty when you're on it! Paired with an accessport, this exhaust will not disappoint. Overall I'm super pleased with this purchase and I'll be dealing with Cobb more from here on out!

Rated 5 out of 5 by from Catback exhaust on my 2008 335i Touring I just have my catback exhaust system installed on my BMW 335i Touring, it fits, no problem. And with the adjustable tips you make it look perfect. The package is big, and traveled half the world to come to me, everything in the box was carefully wrapped and secured, so no damaged items. The sound is beautifull, just that bit more agression in it, not to loud and now you hear the turbo's even better. I am very happy with the quallity of the product, nice welds and solid material.

Rated 5 out of 5 by from Awwwesome! Had this Cobb exhaust for like 2 months now on my 2010 BMW 335 I xdrive coupe. The sound from this product is just perfect for me. Its not to loud when I start up 5AM to go to work. When u shift gears it has such a nice sound to it. When u get on it, it sounds so cool from a distance. Puts a smile on my face every time I take off at a light . I do notice a little more performance. I do have dual intakes, air scoops right now. Also brings out the stock twin turbos in the car. Overall your paying more for the awesome sound, craftsmanship and looks in my opinion. Hands down just get this product.

Rated 5 out of 5 by from Amazing I got my dps installed today on my 08 e92 and all I can say is wow. I recently bought catless but after watching video after video I decided to return them due to the rasp on a e92. These catted Cobbs sound just like stock 0 rasp stock on 1-10 loudness scale is a 1 these are a 2-3. Great job cobb on always having awesome products. Oh and my wife didn't even notice ftw

Rated 5 out of 5 by from What a difference! '11 335is convertible. I did the AccessPort, charge pipe, and air filter and noticed a nice boost with the Stage 1 upgrades. These catted downpipes, wow! Exhaust note on the stock pipes has much more grunt when on the gas. Still purrs while cruising. Noticeable power boost across the full RPM range.

Rated 2 out of 5 by from Good Product but wrong Gasket I was sent the wrong gasket twice. Ended up going to the local auto part store to find one that would fit.

Rated 5 out of 5 by from Quality Product I'm just extremely pleased with COBB so far. I usually am not one to write reviews, however; I am very happy with the set of products I have purchased to far. I currently have been upgrading a 2007 N54 335i (e90). The current COBB products I have are the air filter, downpipe (catted), exhaust, and V3 tuner. All of the products are clean sounding, not raspy, and the exhaust does not have a drone on the freeway. I recommend getting this package, just find a good shop to do the install for the downpipe. Not easy, especially on an Auto.

Rated 5 out of 5 by from Awesome fit and sound You will need the Cobb tuner to go with these or your check engine light will throw, awesome sound, feel like the car flows and runs better
