I purchased that crazy seal the TRL use to sell but once he sold the site to Tony I haven't seen it since. So what can I get to seal the exhaust flange?

Permatex, High temp silicone. You can get in in Red, Gold & Black.
Dont be afraid to glob it on & once you see any seepage after running for a while, pull the pipe & reseal it again.

Don't use the high temp Copper stuff whatever you did. HUGE mistake. You will be lucky if the pipe ever comes off again.

Thanks Neil! I have the High temp silicone. I used that on the Sparks pipe and it worked well. I nned something for the flange and should I be concerned where the pipe meets the silencer? Thats not a very good fit either.

Permatex Ultra Black, clean the flange and pipe of any oil with brake cleaner then apply a thin coating on the pipe end then put a larger amount on the cylinder side flange.
Push the pipe on, wipe away the excess that pushes out and wait a minimum of 3 days or longer, the wait time is the key to it lasting or failing.
On the connection joint of the pipes 2 halves you do have to be careful of it being very hard to remove, but at the cylinder its almost never a issue.

I run this between the pipe and silencer. Works awesome. Can't beat it.
