Stainless Exhaust System

Cobb's 304 stainless exhaust systems use CNC mandrel bent tubing for accuracy and precise fitment and are TIG welded for quality and appearance. This system uses 3 inch diameter tubing from turbo back before splitting into two 2.5 inch tubes feeding separate straight through performance mufflers. The downpipe utilizes a large cast stainless bellmouth design for smooth flow and reduced backpressure. It also incorporates a GESI spun metal substrate high flow cat. Two O2 fittings allow the installation of a wide band sensor for AFR gauge if desired. The twin mufflers exit into quad 3.5 inch tips. The straight through design has been engineered with a sporty sound without being overly loud and obnoxious. Supplied with all necessary gaskets and hardware.

Usually ships in 1 to 2 days.
