05-09 Legacy GT Perrin Two-Piece Catted Downpipe

Perrin's 05-09 Legacy GT two-piece sectional downpipes feature 3" polished stainless steel piping for long life and a great look. The front section utilizes a divorced style housing with a diverted wastegate design for optimal flow, especially on stock or smaller aftermarket turbos. Perrin's wastegate diverter separates exhaust gases behind the turbo and channels them into the exhaust path further downstream to reduce turbulence and improve performance; resulting in smooth, optimized power.

Both the front and rear sections of the Perrin two-piece high-flow cat downpipe sections incorporate a single, 49 state legal catalysts to keep you emissions friendly while still improving power over the restrictive OEM cats. Perrin utilizes high efficiency metal substrate catalysts for optimal performance. These high-flow cats are legal in 49 states as replacements for a defective, missing, or worn catalyst but are not CARB legal.

The front and rear sections of the Perrin Legacy GT two-piece downpipes use 1/2" thick flat flanges to prevent warping, and will bolt to an aftermarket or stock catback exhaust. While Perrin designed these components to be able to be used singularly (i.e. replacing your OEM rear section with the Perrin rear section and maintaining your OEM front section--or vice versa) we have had the easiest time with fitment when both the Perrin front and rear sections are installed at the same time. Perrin's Subaru downpipe catalysts are backed by a limited warranty.
