Description

The MBRP ARMOR Pro 3-inch cat-back exhaust in Race Profile is the most aggressive system MBRP offers for the Subaru WRX and WRX STI. The Race Profile deletes the mufflers for a straight-through, head-turning sound, while full T304 stainless steel construction with a lifetime warranty keeps it looking and performing its best. The 3-inch to dual 2.5-inch mandrel-bent tubing routes exhaust smoothly for maximum flow, exiting through a quad rear exit with mirror-polished 3.5-inch single-wall tips. Bolt-on installation uses the factory hangers with no cutting or welding required.
