PERRIN has been known since our inception for the quality of our Up-Pipe. The Up-Pipe was the first product we ever released and has been a leader in this market ever since. Our 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?
*Precision CNC Bent Tubing* 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.
*Critical Correct Sizing* 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. For a stock turbo, the 1.75" Up-Pipe is the perfect choice for spool and HP. Our 2" Up-pipe is a perfect choice for those looking for a larger Up-Pipe for higher HP applications.

*Flanges* PERRIN Flanges are CNC machined from 304 stainless steel, 1/2" thick and counterbored on the back side to make a smooth transitions from cylinder head to exhaust tubing.
