pypes performance exhaust is looking for "donor" vettes to test fit new exhaust systems (c-3's amoung them). They usually give quite a discount on the systems if you let them do the pipe mock up / test fit.

They're in allentown philidelphia (spelling), anyone interested , email sales@pypesexhaust.com

 I was waiting or them to come out with their system , emailed them , and that was the responce.

 So any one from the area with rusty exhaust,,,, nows the time  to get a deal. Expecially someone with a 73 BIG BLOCK 4 SP.!!!!! (just so they get my model to fit right

 Also they have videos of various cars & mufflers to show what you'll be getting into, dyno performance sheets of the upgrades too.
