I have a Pypes, M80, catback, duel exhaust that fits 2011 - 2014 Ford Mustang. I installed it about 2 years ago and it is a little too aggressive and loud for my taste. I replaced it with a Magnaflow that suits me much better.
There is nothing wrong with the pypes. They sell for about $625 new. I am asking $350. I have included a pic of the exhaust from the Pypes website.
Please contact me through craigslist email or chat. I won't respond to scams or unreasonably low offers. Sale must be in person and cash only.
