Borla XR-1 Cat-Back Exhaust 2002-2007 WRX/STI

The XR-1 cat-back from Borla combines excellent workmanship with Borla's signature sound, and it's a great value. Plus, it's warranteed for a million miles! (After that, you're on your own.) All 304 stainless steel construction, with 3" mandrel-bent piping, an XR-1 high-flow muffler, a tasteful polished rolled tip, and a nice burble tone that's deep and authoritative.Like all Borla systems, the front of this cat-back has a donut gasket receiver, so it's a perfect fit to your factory downpipe. If you want to attach it to an aftermarket flat-flange downpipe and have a full 3" system all the way through, purchase the 3" downpipe adapter accessory. Fits all 2002-2007 Subaru WRX and WRX STI.
