BMW 335i 135i 1M N54 RWD 3 Inch Catless Downpipes

These 3 inch catless downpipes for the rear-wheel-drive N54 BMW 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 N54 run Stage 2 tunes and beyond.

Good to know

Catless design: an ECU tune or CEL fix is needed to avoid a check engine light. AWD 335xi owners need the AWD version. Intended for off-road and competition use only, not for registered road use.
