The AQ Motorsports downpipe with hi-flow cat substantially improves performance and responsiveness by replacing the 2 restrictive factory cats with 1 high flow unit. The cast bellmouth design greatly reduces restriction at the turbo outlet and flows into 3" mandrel bent piping. An O2 bung is included on the bellmouth allowing for easy installation of an aftermarket AFR guage. The 200 cell metal-substrate high flow cat offers very little restriction.The downpipe to catback flange is a full 3" design for optimal flow.
