I jumped off the deep end and changed the crossover and downpipe on my truck (Flowmaster). What a pain the rear that downpipe is to get in/out!

When I disconnected the old downpipe the flat gasket between the dowpipe and cat fell apart.

None of the autoparts stores around here know what the heck it is. I'm going to try muffler shops today.

Anybody know where to find these?

I'm running it with two layers of pop cans smashed between the flanges for now.:grd:

By the way...I can now hear my turbo. Thanks guys!

I had to get mine from the stealer. my 2 Coke cans didn't last long, FWIW. I don't remember and also didn't keep the part number but it only costs like $8 or so.
