BMW 3-Series Cat-Back Exhaust System is rated 5.0 out of 5 by 6.
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 Cat Back Exhaust (COBB) Cobb does a great job with superior craftsmanship and engineering. Always a good bet with these guys. The exhaust sounds great when your on the throttle and the performance is an improvement with about 18 lbs less weight.
