Invidia Q300 Cat-Back 2004-2007 WRX/STI

We like Invidia products for their excellent quality and great fit. The Q300 is Invidia’s quietest exhaust, with an oversized muffler for maximum sound absorption while still maintaining good exhaust flow.

This exhaust systems features all-stainless 3″ mandrel-bent tubing, with 4″ diameter exhaust tips. There’s a flat flange on the front, so they’ll fit up best to an Invidia downpipe, or other aftermarket downpipe with a flat flange. They CAN be fit to up to the stock downpipe’s donut gasket, but it’s not going to be an perfect seal.

Fits all 2002-2007 Subaru WRX and WRX STI.

Availability note: Supply on Invidia products has been spotty. Please call about product availability before ordering.
