Exhaust Gasket Question
'm getting ready to install a Supertrapp 2-1 system on my bike. In the instructions it says to use regular stock HD gaskets only. Has anyone used the SE gaskets with a Supertrapp 2-1?
I have a brand new pair of SE gaskets, and was planning on using them with the exhaust. But after reading the instructions, I'm left wondering if the SE ones will work or what the reason for them saying stock only.
Any help would be appreciated.

RE: Exhaust Gasket Question
interesting...
i used the se gaskets when i installed the v&h big shot duals. i do get decel pop, doesn't bother me (too) much. can't help but wonder if i'm getting a good seal between the pipe, gasket and exhaust port. if i put my hand near the ports right after starting bike to check for leaks, it's very difficult. sometimes it feels like i can feel a little puffing action, but it's hard to discern with all the heat. i did torque all four nuts to the proper torque, in the proper sequence. i have decided that the next time i pull the exhaust, i'm going back to stock gaskets. i understand that the se are supposed to flow better, and prolly do, but i'm not trying to break any land speed records. there is much more meat on stock gaskets, hence, they should seal better. this could be the reason supertrapp recommends stock over se.

The reason I'm going to use the SE ones is that I have ported/polished heads, and Bean at Big Boyz recommends using the SE gaskets. The SE ones don't crush down as much and as a result will not block off the porting job.
Right now I have the performance gaskets that came with the Rineharts in there right now, they do not compress at all. They are a different material then the HD ones. I might even try those and see how that works.

I could never get the SE ones to seal on my bike. Ended up going back to the stockers. I think the key with the stock ones is to make sure you don't over torque them. If you do you could end up with material blocking the port.
I'd do like you mention and try to use the Rhiehart ones. Can't wait to hear what you think of the new pipe.

RE: Exhaust Gasket Question
I had problems with my V&H ProPipe sealing up with the SE gaskets as well....so I asked around and got a tip from a few guys to use the crushable metal type gaskets like White bros. makes, or these by Novello:

I went with the Novello because they were easier to get. I thought they would work well since some of the most recommended head gaskets, and the ones I also use are the multi-layer steel (MLS) cometic gaskets...proving you don't need a 'fibrous' gasket for a good seal.
Anyway, to get to the meat of it, I have not had an exhaust leak for the last two years with these gaskets....even though I've had the exhaust off twice and reused the same gaskets...I'm very happy to recommend these to everyone.
