Perrin Performance Up-Pipe 1.75" For Turbo EJ 06-14 WRX 04-21 STI
The PERRIN Uppipe is one of the best ways to increase the power and throttle response on your Turbocharged Subaru. Our Uppipe was the first product we ever released and has been a leader in the market ever since!
Add Horsepower
The properly sized and smooth bent PERRIN Uppipe adds 5-10 WHP and 5-10ft-lbs of torque across the entire RPM band.
Precision CNC Bent Tubing
304 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 Uppipe 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" Uppipe is the perfect choice for spool and HP. Our 2" Uppipe is a perfect choice for those looking for a larger Uppipe for higher HP applications.
Flanges
PERRIN Flanges are CNC machined from 304 stainless steel, 1/2" thick, and counterbored on the backside to make a smooth transition from cylinder head to exhaust tubing.
No Tuning Required
Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle.
Emissions
We have reviewed the design and internally tested these parts to comply with EPA’s Anti-Tampering Policy, and the CARB / EO process has not been completed. At this time, the product is legal in California only for racing vehicles that may never be used upon a highway. Check your local and federal laws prior to installation.
