aFe Racing Downpipes 07-10 BMW 335i / 08-10 135i 3.0L / 11-12 335iS / 11-12 1 Series M Coupe
The aFe Power racing down-pipes eliminate the catalytic converters for maximum exhaust flow for the popular BMW 1 series and 3 series with the N54 twin turbo motor. In recent dyno testing, these race pipes produced 17 horsepower and 32 ft. torque over the factory down-pipes! These high performance race pipes are constructed out of lightweight, TIG-welded, 3 inch, brushed finish, 304 stainless steel and use thick 3/8 inch 304 stainless steel flanges for a leak-free seal and a factory fit.
Note: A check engine light can be expected and tuning is recommended.
