I have a Magnaflow 16633 cat back exhaust in excellent condition for sale. Sounds awesome but it's just a little loud for me. About 1,000 miles on it so it's just nicely broken in.
Asking $350 plus actual shipping. I'm in Ontario, Canada so it may be a bit pricey to ship to the USA. I'm willing to drive up to an hour to deliver it or meet part way for anyone in Ontario or close to the border.
