We are proud to introduce VRSF 3" catless downpipes for the N54 135i & 335i which now feature a cast stainless steel mouth. These 3" downpipes are THE best bang for the buck mod available, with gains ranging from 25-30hp when tuned. By eliminating the restrictive catalytic converters in the factory downpipes, backpressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note.
This item fits the following BMWs:
These these parts are for OFF ROAD / RACE USE ONLY . They are not 50 state legal. These parts WILL NOT be sold in CA. We advise you to run a tune on your vehicle for best results and to eliminate the check engine light.
