how to seal exhaust? ok i have my PS LT's and ORY i have them slipped together and band clamped but the band clamps arent making a complete seal, wherethe 2 ends of the clamp meet there is still some leaking and u can hear it under the car especially on deceleration alot.
im wondering what i can use to seal it up, my only idea has been to use those muffler bandages they make and wrap the edge where the Y is slipped on the headers and then clamp over that and hope it doesn burn off real quick. anyone else got an ideal i dont wanna weld it becuase id like to be able to get it off and i do plan on gettin a new Y and catback in the future when funds are better lol

I read that aluminum tape works well on exhaust joints. You can pick it up at Home Depot or Lowes etc.
Stainless Works suggests using high temp silicon to aid with sealing and allow for easy dismantling down the road.
Another way to get a better seal is to cut tree thin notches, ~0.5" in length, in each female pipe. This will allow for more flexibility in the female pipe, providing a better seal. (Also recommended by Stainlessworks.)
In each scenario, a band clamp is then used over the joint.

Go get some aluminum foil from the kitchen, fold it over a whole bunch of times with a whole bunch of layers. Take the clamp off and put the middle of the strip right on the end of the overlap of the pipes and wrap it around, put the band clamp on top of it, and use an impact to suck it down.
I tried a muffler patch on my driverside when i thought it was leaking, but it wasn't what was leaking. The patch turned rock solid and was a BITCH to get loose when i yanked my heads off to swap the lifters.

im thinking of incorporating all your ideas, im think i may try putting some hig temp silicone on the endge of the overlap and then wrapping that with the aluminum tape or foil and then tightening the clamp down over that if that doesnt solve it i dont know what will
I have them same problem. I have tried most of the things mentioned above and none of them worked. I'm just going to have flanges welded on. Hopefully that will be the end of the problem.
