Invidia High-Flow Catted Downpipe with Additional O2 Bung for 2002–2007 Subaru WRX and STI

Description

The Invidia Divorced Wastegate Down-Pipe replaces the two factory catalysts with a single high-flow catalyst, and a much less restrictive design. This allows your Subaru to make more power with the stock turbo, and this is an absolute must if you are going to be putting on a larger turbo.

Gaskets are sold separately, and this down-pipe has a 3″ flat flange, allowing it to attach perfectly to most 3″ Cat-Backs.
