BMW E90 E92 E93 335xi N54 AWD 3 Inch Catless Downpipes

These 3 inch catless downpipes for the AWD BMW 335xi N54 remove the restrictive OEM converters so the exhaust flows freely, increasing power and torque.

Why you need it

Gain up to 25 whp and 37 wtq with an improved exhaust sound. Because higher boost generates more heat, they let your AWD N54 run Stage 2 tunes and beyond.
