Arc it? Kinda perminate though... Not too certain about your removal/installation circumstances.

Theres a type of fiberglass packing that you can wedge in there. I used it on my quad few years back and worked great.

Also, Bubble Gum and Bailing Wire Repair. You can go to the parts store and they can help you find a heat resistant puddy material. To go along with that is a heat resistant strap that you "wrap" around the puddy after being applied. Attach two hose clamps to insure security. This was done years ago to my dads truck and only as a temporary fix. It ended up lasting years!

go to an autoparts store and see if they have a exhaust expander available for rent, if you leaking is caused by fitment that is too loose than you can expand whatever side you need to, to make it fit better

Use the orange/copper high temp silicone, AND one of those 2 1/2 - 3" wide stainless band clamps. Summit carries them as well as jegs. I get them from the local NAPA store. They carry them for pipe diameters from 1 1/2" - 5", with almost every size in between.

They are polished stainless steel so they look good, and in combination with the silicone will not allow exhaust to escape. I use them exclusively on all of my exhaust system (all slip fit) because they are easy to remove and the silicone lubes the pipe joint enough to make the pipes come apart easily while still maintaining a good seal.

Your looking for something similar to this, but summit doesnt seem to carry any smaller.

Cant think of the brand that NAPA carries, but they have almost ANY size.

i thought about an exhaust expander but it only needs a TINY amount...

thsi si my second set and theses were used think the previous guy had trouble getting it out and rocked it back and forth and expanded the pipe
