Vance & Hines Exhaust Leak Help

[_Brian_]

Since installing the Vance & Hines slip-on dual exhaust I've had an exhaust leak that i cannot get rid of. It leaks on the right side where the muffler meets the head pipe. Already tried 2 new gaskets with no luck. If you look in the pic below, the leak is coming out of the two slots just in front of the clamp. It almost seems like the exhaust air is getting under the gasket inside the pipes and then exiting through these slots. Clamp is very tight with 1/4 in of threads left. Anyone else had this issue?

Are these Vance and Hines Slip Ons or a complete exhaust?

looks like your band clamp has reached its maximum potential, I would put a gasket in or a thicker one if you already have one in there and slide the clamp down toward the bell of the fitting

Band clamp still has 1/4 in of thread left before bottoming out and is tight.

Did you use a new crush gasket or the old one?

New gasket

Looking at the picture it doesn't look like the muffler is pushed in far enough. I'll have to look at mine and see if it's doing the same thing.

The exhaust can go further in but then the 2 bolts for support bracket won't line up. As of now I have the muffler pushed as forward at it will go and still be able to mount it.

had this issue when i cut slits too long installing a thrush muffler. Advance auto has band/muffler clamps, maybe find a wider version of what you have and throw that on? Thats what fixed mine.

I would contact Vance and Hines and see what they have to say.

HwyRider..Did your exhaust look the same?

[skullbagger]

is that your gasket poking out from the right side of the pic.
it needs to be in further for a seal. it may not be wide enough, I would take it all apart and re- install making sure the gasket reaches the slots in the pipe then clamp it back there

Thanks skullbagger. I was thinking the same thing first time around. The gasket is in as far as it will go and completely covers the slots. The left side is the same way.

Where would you find a thicker gasket? Also the housing has a tab on it that fits into a slot on the band as shown in pic. If you try to move clamp toward bell then it will not close band evenly around exhaust. I may have to just grind this tab off and use a wider band.
