RENNtech Downpipes are constructed from T304 High-Strength Stainless Steel and are equipped with 200 Cell Sport Catalytic Converters.

With the replacement of the stock downpipes we improve performance, reduce back pressure, increase initial turbo spooling and enhance sound output.

RENNtech products are manufactured to perfectly match the stock GLC and C 63 AMG exhaust system, as well as the RENNtech Sport Muffler System and include all necessary mounting hardware and clamps.

Our downpipes are designed and manufactured at the RENNtech Headquarters in Stuart, Florida.
