Perrin’s rotated downpipe features a wastegate dump tube to recirculate exhaust gases back into the exhaust system. This eliminates the risk of fire and melting underhood components from high heat rushing from the wastegate. Perrin’s competitors don’t offer this level of safety and performance, instead choosing to dump those raw gases directly into the engine bay. The PERRIN downpipe dump tube features a slip fit that allows for quick removal of the downpipe. Like our other exhaust components, the downpipe is TIG welded, CNC mandrel bent, 3″ 304SS tube with .500″ CNC cut flanges. It is also designed to bolt up to your PERRIN or OEM cat-back exhaust.
The Rotated up-pipe is TIG welded, CNC mandrel bent, 2″ 304SS tube with .500″ CNC cut flanges. The external waste gate is plumbed into the up-pipe with a smooth transition, from up-pipe to wastegate, allowing for increased exhaust flow and perfect control of all boost levels. The up-pipe is designed to bolt to a factory exhaust manifold or PERRIN headers, and fit a T3 Turbine housing from a Garrett GT30R, GTX30R, GT35R or GTX35R.
