aFe Power Downpipe Header BMW 335i ('07-'10) 135i ('08-'10) L6-3.0L (tt) (N54)

The aFe Power Cat-Delete Down pipes eliminate the catalytic converters for maximum exhaust flow for the popular 1-series and 3-series BMW with the N54 twin turbo motor. In recent dyno testing, these race pipes produced 28hp and 28lbs. x ft. torque over the factory down tubes. These high performance race pipes are constructed out of lightweight, TIG-welded 2-3/4" brushed finish 304 stainless steel and use thick 3/8" 304 stainless steel flanges for a leak-free seal and a factory fit.

Also fits: BMW 135i 08-10; 1 Series M Coupé 11-12 L6-3.0L (tt) N54

All aFe exhaust systems are engineered and manufactured in our Corona, California manufacturing facility.
