The engineers at Mishimoto designed this cat-back as a four-piece design with precision TIG welded 304 Stainless Steel. This allows a smooth exhaust flow from the 3.0" 2-bolt exhaust flange all the way through the 2.25" y-section. To top it off, this cat-back includes two 2.25" V-Band clamps, a 3" exhaust band clamp, a new 3" 2-bolt flange gasket, and all stainless steel hardware, so you don’t have to worry about your hardware rusting ever again!
