If the leak isn't really bad maybe try some permatex rtv and the clamp? Also IMO don't use the u clamps the flex pipes come with. Find Harley Davidson exhaust clamps on eBay. There really good and cheapAttempted this earlier. I got pretty much everything done, but when I was putting the front side of the flex coil to the header pipe, it's really loose. I tighten the U-clamp over it, but it just crush flex-pipe, which creates a crazy leak. What did you guys use to as filler or shim?
I'm going to have to get another flex-pipe to try again tomorrow and maybe some kind of shim or seal of some type since the flex pipe is slightly too big and doesn't crush down well to seal over the header. Maybe cutting some slits into so it doesn't crush in and actually folds in?
I'll try again tomorrow and see.
I Lost the Web Page/Link, but have Copy & Paste:Permatex high heat sealant is your friend for exhaust leaks
Also both those acorn nuts have specific torque specs on them, if you over or under tighten them they will leak. im not she what the exact torque spec is im on the road, someone well chime in with it,if not I'll get it for you when I get home
Thank you Wm....for once we agree, lol....X2..
