The Perrin 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 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. Check out the details at: Big Tube Up-Pipe
All 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.
