Default Tuned pipe exhaust leak ideas

I'm getting an exhaust leak from where the head pipe slips over the manifold stub. Tried wrapping the stub pipe with the yellow Teflon tape and that lasted about 5 miles and blew out. Was thinking of wrapping it in tinfoil next.
What would be perfect is some kind of a high heat O-ring where the head pipe sits against the exhaust flange.

Today was the first time I was able to really ride after installing the tuned pipe a few weeks ago and let me tell you, if you have any doubts as to whether a tuned pipe adds power IT DOES! Before the Teflon tape let go I was cruising at 29-31 on the flats and uphill grades that usually dropped me down to around 20 I was holding steady at 27 all on a standard 44T sprocket.
