Perrin Uppipe Subaru Legacy GT 05-08

PERRIN has been known since their inception for the quality of their up pipe. The Up pipe was the first product they ever released and has been a leader in its market ever since. This up pipe is one of the best ways to increase the power and throttle response on your Turbocharged Subaru. Why go with an imported imitation when you can have the original?

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. Flanges are all CNC machined from 1/2", 304 stainless steel to prevent warping. Flanges are now counter on the backside for smoother transition from header to tube and up pipe to header. The center bores of the flanges are port matched for a smoother exhaust flow. Proper sized ports increase exhaust velocity and assure gaskets will not burn out.

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 you will see 250-350 RPM quicker turbo spool up after installation. Choosing a tube bigger than this can cause the turbo to spool slower.

NOT: NOT street legal for use on 2005 models with catalytic converter in factory up pipe.
