Mongoose exhaust systems are formed from 1.5mm wall T306 stainless steel tube on state of the art CNC machines,  Mendrel bent (not cut & weld).  The silencers are formed from polished stainless steel and packed with the highest quality materials available. The systems are finished with a choice of highly polished tailpipes and tests have shown that a Mongoose can give more power than any other aftermarket exhaust system. The prices in our online shop are all at 10% discount off the RRP.
