Product details
These RS Q8 race downpipes replace the original catalyst sections with a straight-through route. They are the catalyst-delete choice, rather than the HJS sport-catalyst version. Fabspeed Motorsport designs performance exhaust systems, air intakes and ECU tuning in Fort Washington, Pennsylvania. Porsche and other sports-car applications are developed through dyno testing, road evaluation and racetrack work.
