VRSF 3.5in Cat-Back Exhaust E90/E92 335i, 335is | 2007-2012

The VRSF 3.5-inch cat-back exhaust replaces everything from the downpipes back on the rear-wheel-drive E90 335i sedan, E92 335i coupe and 335is. It works with both the N54 and N55 engines. Choose the street version with mufflers for a deep note that stays civil on the highway, or the race version for the loudest, lightest setup.

What It Does

The factory exhaust is heavy and uses small-diameter piping with restrictive mufflers. Moving to 3.5-inch piping reduces back pressure, which helps the turbos spool and lets a tuned car breathe more freely at high rpm. The system also saves more than 40 pounds over the stock exhaust, all of it at the back of the car.

Materials and Construction

The system is 100 percent 304 stainless steel, mandrel bent and hand TIG welded with smooth radius bends. The tips are adjustable and replaceable, so you can set their position in the bumper cutouts. Installation hardware, high-quality steel gaskets and clamps are included.
