Autotech continues to push the performance exhaust system envelope. Extensive research and development time was spent in conjunction with industry icon Magnaflow to improve on the factory offering, as Volkswagen has done a great job engineering the stock Golf exhaust for ample flow. We're proud to have met that challenge and now offer our Autotech SportTuned Stainless Steel Cat-Back Exhaust Systems for the Mk7 Golf models.The 2.5" diameter, 100% stainless steel tubing is larger than stock and mandrel-bent for maximum flow. Plus Autotech laser engraved logo 3" tips.
