Without a doubt, the VRSF 3″ Catback Exhaust for your N54 & N55 135i is THE most cost effective option in the market. This exhaust is made from the highest quality 304 grade, mandrel bent stainless steel and we include super-flex, stainless steel band clamps to ensure quick and easy installation. By increasing the overall diameter of the piping to 3″, back pressure is reduced significantly which results in faster spool, and MORE POWER.

The VRSF 3″ Street Exhaust merges the two downpipe connections into one 3″ which shaves about 34 lbs of total weight over the OEM exhaust. At idle, the street muffler’s exhaust note is subtle and slightly louder than stock which transforms into a deep, distinctive note at wide open throttle due to our use of a single 3″ primary.
