Do you have any pics of what it should look like? I have a metal triangular shaped "gasket" that was on the car with the ATR up-pipe. Do I use the same piece for both up-pipes even though they have different mating surfaces? I was under the impression talking to jaysgn that I needed a "doughnut" gasket for his pipe. Sorry for any confusion, I just want to make sure about this stuff. I am about fed up with the exhaust on this car. First problem was the 3" Houston style downpipe I bought hitting the a/c box, so i'm back to using the stock downpipe. Then I put the poston header on, and the crossover pipe dosen't fit properly. It's only about a quarter inch off but it's enough to give me problems with the pipe sealing. I tried to put the jaysgn up-pipe on and the two holes where it bolts to the header are slightly wider than the holes on the poston header! So I took out the dremmel and went to town. Even after all that, with the nice little flex joint in the up-pipe, its still gonna be a b!T@# to get it seated properly. I'm pretty sure its the poston header thats giving me problems but this is just frustrating. I don't want to put the stock pipes back on, even though they are the only ones that actually fit without any problems. I'm sure you are tired of reading this now, I just needed to vent a little. Thanks for the help.
