That sucks !
I had a muffler shop quote me a killer deal on a 3" exhaust over the axles and out the back . So I brought my old tail pipes with the original tips to them and waited.... after a few hours they decided they could do it ( which didnt surprise me) so I got in my car (73 340 4sp Dart Sport) and went home . A week later I was trying to find those tips.... They threw them out ! I was furious ! Fuckin idiots couldnt do anything right !
