Subject: [Healeys] Exhaust fitting

Hi Folks,

After many years of service my old stainless exhaust system has had it, and I’ve decided to replace it with another stainless system.
I wonder if any of you have some tips/tricks for getting a good gas tight fit at the joins. 
I’ve had my car for 45 years and I’ve struggled many times with controlling fumes. I’ve recently replaced the manifold gasket, made up down pipe gaskets out of Remflex ( a graphite exhaust gasket material that compresses), lengthened my old tail pipes, and carefully checked and sealed the firewall.
It’s become a bit of an obsession for me, so, since I’m starting with a new system, I’m hoping to see an improvement.

Suggestions?

Thanks,

Stephen, BJ8

I've had success sealing gaskets and small leaks with high-temp 
silicone. Edd China used to use some kind of blue paste, but haven't 
seen any like it around here.

ps. The fumes you're smelling might be coming from the end of the 
exhaust; if the tip doesn't extend past the rear bumper they can 'curl' 
back into the cockpit.

Hi Stephen -

I always use SS T-bolt hose clamps or other heavy duty equivalents to clamp
down on the joins... mostly because I hate the little whistling sound from
otherwise weak clamped joins.  The T-bolt hose clamps also have the added
advantage of not creasing the joins, so disassembly later is super easy.
Best part is there's no need for silicone sealant or anything like that.

Mikalor is a very good brand, alternatively you can get them from boat
shops too, but make sure you get them with the solid SS T-nuts so that you
can crank down on the bolt:

alternatively this kind is very good as well:

https://www.theboatwarehouse.com.au/plumbing-sinks-toilets-pumps/hoses-acce=
ssories/hose-clamp-stainless-steel-t-bolt/

Avoid the kind that don't have a solid T- nut or don't have complete
threading through the T-nut.

Best,

Alan

you want T-bolt clamps with "solid trunions".... that's the word I was
looking for.
