I've got some popping in the exhaust, and a definite air leak at this juncture going to the right side can.  It doesn't slip on all the way, and thinking that there must be a gasket that can fit in there.

This is a 2008 S2R1000, dual sided full Zard system.

Yes, I made sure that the exhaust header/maniford gaskets are done properly, it is definitely coming from this juncture.

Hey superkain,

I have a tiny leak in the same junction between my Marving header and the stock midpipe. It just isn't a perfect fit. Now that I have it apart for maintenance, I think I am going to try some of this

It says it is good up to 700F intermittent. I wish I would have hit my pipes with an IR thermometer before I took my bike apart, to see how hot they normally run. I also wonder if this will make it a complete pregnant dog to remove the midpipes later on, since I seem to pull my rear wheel off pretty often.

You can see the black line in the pic where exhaust gas has been escaping.

HTH

Let me know how it goes!

Google is losing your pics

I had this issue with a poorly built quat D exbox. Permatex copper is good stuff but if the gap is big, the exhaust pulses will push that stuff out in about a week.

Also look in to wurth exhaust assembly paste. Its got a higher temperature rating and the fact that it sets with high temperature

Thank you!  I'll start with the copper, as it's less expensive. If that fails, I go to Wurth!

Muchas Gracias!

Permatex Copper blew out in about a week, just as you said.

Just ordered some Wurth sealant, and going to give it a try.

I hear harley davidson pipes have tapered exhaust gaskets, and i'm thinking i might even be able to modify one to fit if it comes to it!
