An Axle Back Exhaust system is basically a rear damper with piping made to fit your existing mid section. This is only the last part of a full exhaust line. An Axle Back exhaust has a little less performance gain but does create a deeper, sportier sound.
Axle Back exhaust systems are possibly the easiest exhaust upgrade to install - it is usually a bolt-on modification that requires no special tools or extensive know-how.
Manzo USA utilizes the same R&D and technical knowledge as a well known exhaust manufacturer from the USA. The aim is to offer a high quality performance part at an affordable price. Manzo USA uses mandrel bending technology, CNC machined flanges and polished stainless steel material.
