Exhaust gasket question

[7Dust]

Replacing the j pipe on my turbo deuce with a good used one and found the remnants of a gasket between the flex pipe just after the turbo and the j-pipe.

Ive never seen gaskets used on v-band setups before.

If I do not replace the gasket between the flex pipe and the j-pipe, will the v-band seal the joint or do I need to source a gasket?

Is there an off the shelf replacement available at Auto Zone or O-reileys? If so, what can I cross reference it as?

Thanks in advance.

When Hammer and I swaped my turbo, I dont believe we replace that gasket, but I had been up for over 30 hours at the time of the swap, so my memory is a little fuzzy.

i've seen some with and without the gaskets. the v-clamp gives a good seal!!

It will be fine with no gasket. Install it clean and you'll be ok.

Use a block of wood with emery cloth on it to make sure the turbo end is flat and clean and it'll be OK w/o a gasket.

^^^ Its not mating to the turbo - its mating the flex pipe to the j-pipe.

When a V-band clamp joins a joint with flat mating surfaces, a gasket should be used. The gasketless ones have a tapered mating surface to make the seal.

That said, they almost always work just fine without the gasket. Make sure it's a clean and flat joint. Further, in an exhaust such as this where there is lots of smoke (particulate matter that clings to whatever it touches...), you have an endless supply of "fix-a-flat" being pumped through the system. Aim for perfect, but if it's really close but not quite perfect... it'll probably be perfect before long.

Same thing applies.

Confirmed. Installed the J-pipe with no gasket and no detectable leaks.
