How do you seal exhaust joints?

Hi all,

Working through my long list of winter maintenance and will have a look at the exhaust soon.

I have an 81 with stock replacement exhaust (stock dimensions and style but aftermarket pieces).

The slip joint from the resonator to the muffler has always leaked on my car. I have tightened the clamp to point where I feel I will crush the pipe soon. Putty and paste do not seem to last long.

I can hear the leak which is annoying and I can smell the exhaust when sitting in traffic. Looking forward to fixing this one.

Any suggestions?

use an expander to properly resize the inside pipe

Thanks Mark,

Anyone have a DIY solution for an expander?

Weld it shut

expanders that you use a socket on are available for not much money. Or go to a muffler shop and ask them to resize it for you

I prefer the stainless band type if its ever to be taken apart or the guillotine type if you want a crush clamp. You can see the styles here:

+1 on the band clamp. They work great.

Thanks All,

I went for a different clamp style and it seems to be working on my garage test.

Cheers,
