The 08-10 Subaru WRX PERRIN Up-pipe is one of the best ways to increase the power and throttle response on your turbocharged Subaru. 321 stainless steel tubing is CNC mandrel bent and precision welded to perfection. This eliminates the need for a flex joint, which is a major weakness in other up pipes including the OEM one. PERRIN Flanges are CNC machined from 304 stainless steel, 1/2" thick and counter bored on the back side to make a smooth transitions from cylinder head to exhaust tubing. The PERRIN up-pipe inside diameter best matches the OEM exhaust manifold outlet and OEM turbo inlet. This is critical to maintaining exhaust gas velocity increasing turbo spool up. Typically we see 250-350 RPM quicker turbo spool up after installation. The PERRIN big tube up-pipe has a 2" diameter which best matches aftermarket headers and the inlets of aftermarket turbos.
