The aFe Power cat-delete, race 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 x 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.
All aFe exhaust systems are engineered and manufactured in the Corona, California manufacturing facility.
