I just purchased the Magnaflow 16633 new for my CF. After installing it I find it to be a little loud for my taste. Don't get me wrong, it sounds very aggressive with a warm tone.
In any case I have reluctantly decided to sell it. Before I go to eBay I want the forum members to have first chance. Also my price on eBay will me higher. It is two weeks old and in great condition. I also am including the warranty (still sealed in it's plastic package) for $275.00 plus delivery. If interested PM me. Paypal only. IT HAS BEEN SOLD
