The subject pretty much says it. When I install my new testpipe, can I reuse the existing gaskets at the flanges of the cat pipe I'll be replacing?

 

I did, but I sprayed them with copper gasket sealant just to ensure a good seal.

 

I don't see why not? They aren't pressure formed like the exhaust manifold gaskets or anything. I cleaned mine up and reused them when i took the exhaust apart....

BTW: How are the wheels coming along?

good luck!

Erich,

I haven't had a chance to do the wheels yet. I'll probably get to it in June. Definitely expect pics.

Theyll be fine unless they really stick to the pipes and break off in little pieces

Usually doesnt happen on the stock 944 exhaust...but on the bursch! Ugh!

 

I replaced mine. They aren't that expensive and I figured pay for them now or pay for them later when I am chasing down an exhaust leak.

My dowpipe crush ring was the only one I had a tough time with. Absolutely would not come out - I had to cut into it with a dremel and pry it out with a screwdriver.

All the other ones actually fell out of their channel, thats why I didn't want to reuse them - I doubt highly they would have created a good seal.

I definitely would not reuse any of them on the crossover pipe. The high pressure those joints will see will need the best seal you can give them.
