How much is a Peter Farell cat back worth?
 

Used in good condition??

Like all used parts.......whatever someone is willing to pay :)

Seriously, I've seen them anywhere from about 225 to 350 depending on condition.

a little off topic, but I have that exhaust and I love it. Much better than the apexi unit, I had to get rid of that one.

Snyper,

Are u looking to buy or sell? I recently swapped mine out for the milder sounding RB dual tip version. Was hoping to stay under the radar, too. It is probably still at the shop waiting to be sold. Let me know if you are interested.
