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.

This exhaust system features a 3 inch pipe all the way back, and a 5 inch can-style muffler. Unlike other systems for the Audi A3, this free flow design allows for impressive HP gains.

Downpipe:
This GHL exhaust system includes a 3 inch downpipe with a ceramic catalytic converter (not shown in picture).

Center Resonator:
This GHL exhaust system comes with both a center resonator and a center pipe so that you can choose to run your car with or without the resonator. The center resonator will help to reduce raspiness and lessen the overall exhaust tone.

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.
