The VRSF 3.5″ Catback Exhaust for your N54 & N55 335i is the best bang for your buck option available for your N54/N55. Our 3.5” mandrel bent design significantly reduces flow restrictions present in the OEM system which results in faster spool and MORE POWER. Street Catback: Our 3.5″ Street Exhaust shaves about 42 lbs over the OEM exhaust due to our unique 2 to 1 design from the downpipes through the muffler. 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 3.5″ primary. Race Catback: We also offer a race version of this exhaust which eliminates the muffler and shaves an additional 14 lbs of weight over the standard street exhaust. Please note, the Race version is quite a bit louder than the street version is best suitable for track use. We include a lifetime warranty as well as our “No Hassle” satisfaction guarantee (including fitment). Installation hardware and high quality steel gaskets are included with purchase.
