Review on Pypes Performance Exhaust SFM69 Mustang by Bill Lyons

The installation of the system was horrible as 2 pipes had to be cut and 3 of the 4 exhaust hangers had to be cut and rebent. It was too much work for the system to fit and align in the car. If you want an exhaust where the muffler is at the gas tank or 1/8" away from the gas tank, then this is the exhaust for you. For all the installation difficulties, the exhaust system is twice as long as it will fit in a car, and bolt-on mounting should never be that difficult to install.
