All GHL products are built using only the highest quality “American Made” T-304 & T-321 stainless steel. All tubes are precision mandrel bent and everything is hand TIG welded by skilled craftsmen in Mesa Arizona. Factory mounting locations are used wherever possible to insure a quality fit every time. All GHL products come with a Lifetime Warranty on workmanship and materials. Installation requires simple tools, no welding required.
On the A4 , the catalytic converter is bolted to the turbo charger then the exhaust begins with the down pipe. Unlike most other after market exhaust, the GHL exhaust includes the down pipe. A high-flow catalytic converter is available with the turbo-back system, or available separately as well.
Processing Time: Please allow 5-10 business days (Monday thru Friday) for GHL to construct your custom exhaust system. Your GHL exhaust will ship directly from GHL to you. Once the order ships we will notify you via email with tracking information.
PLEASE NOTE: Catalytic converter is NOT included with this cat-back exhaust system. Catalytic converter can be purchased separately, or with exhaust system as a complete turbo-back exhaust. See link below for turbo-back exhaust system.
