Pypes Performance Exhaust SFM69 Mustang Review

I took this to a professional hood and it took the guy almost 9 hours to install it as the installation was horrible and he had to cut and weld everything. Instead of charging me 250 he charged me about 600 for all the extra work he had to do. If I knew those numbers beforehand I would just pick something like Borla :(

They sound great most of the time, but when I turn on the AC or it's cold outside when I start the Mustang, they rattle and vibrate horribly. Pipes called as I often walked by her house but received no satisfaction. I've tried resetting it myself multiple times. It helped, but the knocks and vibrations returned. Too bad because the Mustang sounds great when the system is working properly.

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.
