Has anyone on this site installed this system on their car because I'm wondering what exhaust gasket do you use from the main silencer pipe to the new secondary pipe. The system comes with 1 gasket and thats for the muffler to the secondary silencer.

Thanks

Ok, your comment was a little...uhn...confusing...


Most Cat backs come with a pipe w/a resonator, an "s" pipe and the axle-back (pipe&muffler)

Some have the midpipe (replacing the 2nd Catalytic converter) included. Or have a one-piece, midpipe/resonator.

In essence, there are two Cat converters. One bolted onto the exhaust manifold, the other is part of the mid-pipe. If you have a header, you get rid of the first but keep the second.

There are two gaskets you have to worry about. The one gasket that connects the CAT to the resonated pipe and the one that connects the "s" pipe to the axle-back (muffler). I think Vibrant only supplies the "s" pipe to muffler gasket and you are to re-use your stock CAT to resonated pipe gasket.

If this gasket is really chewed up you can go to a muffler shop or an autoparts/performance shop with the old gasket and ask for a replacement.


This gasket is round like a donut gasket ( gasket from exhaust manifold to catted pipe)but flat, instead of tapered, unlike said donut gasket.

Hope I made myself understood and this helps.

Yes the cat gasket no longer works with this setup because the collar is no longer on new section. Had to use a combination of 2 flat gaskets with a new factory doughnut to get it to seal. If that ends up failing I will have to search out another type of doughnut.

Doughnut as in the tapered one or the flat one?

Flat one should work just fine.

Happy to hear you found a solution.

Yeah it seems to have sealed nicely but if those flat gaskets fail then I'd have to look for those header type donuts. The only problem would be getting one to with 2 3/8 pipe -> 2".
