These new A1 Class 11 exhaust systems are the answer for anyone looking for maximum ground clearance, HP, and performance in a very compact package. Not only do these work for off-road cars but they are also perfect for anyone with an ultra low car looking for an exhaust that works and fits in a very nice tight spot behind the apron. These systems are made in T304 stainless steel, fully Tig welded for a seamless finish with smoother mandrel bends. All kits use a V-band connector between the header and muffler as well. Kits are available in several sizes and finishes which you can choose from below. We have this exact kit on our project Highwheeler bug build which can be seen in the project cars section of our website. All Class 11 kits include both the header and muffler.
