I have a 2.5" diameter catback for sale.
The piping is welded to the stock cat, and it is crush bent. It has a resonator and is terminated with a stainless steel Magnaflow muffler with angle cut tip. Tip diameter is 4.5" or 4" I believe, can’t remember exactly.
$100 takes it.
Here are some pics and a vid of startup and reving. (3000, 2500, then 7000 RPM)
