Let your turbos breathe and increase horsepower with a set of Catted Downpipes designed by COBB. 5B1202 fits RWD BMW 335 335is 135i 1M.
The best way to free up some horsepower in your force inducted vehicle is by letting the turbo breathe. COBB's 3" catted downpipes are a direct replacement for factory downpipes and feature a 200 cell high flow catalytic converter and 304 stainless steel tubing. These downpipes provide a free flowing exhaust out for the high energy exhaust gasses which reduces back pressure and increases turbo efficiency. There is off-the-shelf mapping available for the Accessport to take full advantage of these downpipes.
