BMW N54 Catted Downpipes is rated 4.5 out of 5 by 13.
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 4 out of 5 by from Downpipes install I bought these a few weeks ago and they were more difficult to install then I imagined from the instructions. Mainly because of how tight the fit is , but they fit great and lined up perfectly to the oem exhaust. The sound is low in the vehicle but sounds way better at high RPMs when you are out side the vehicle , can't wait to go full exhaust and have that deep throaty sound. Great product from Cobb as always

Rated 3 out of 5 by from Cost of installation Installation cost more than I expected. Partially my fault, I guess, as I had it done by BMW technician at dealer.

Rated 5 out of 5 by from Another Great Product from Cobb Can’t say enough good things about the build quality, and most importantly, the fit of these pipes. The cast outlets are an especially nice touch with the benefit of dealing with the close clearances around the turbos in the 135i. Highly recommended!
