Greetings!

I have owned a nice old restored 1962 R60/2 for about 5 years now. I now have the challenge of replacing my exhaust system - it was just old and it is time.

I bought a full new chrome replacement system from Bench Mark Works and it looks great.

Question: Should I use any sealer or cement between the muffler and header pipes - and on the crossover pipe? I looked all of the 'net, and could not find many opinions to go on. I gather that I can just press fit them, or perhaps use some normal, or high-temp (coper) silicone. Anyone have any opinions on this perhaps?

Thanks for any tips!

-Sean

The joints would fit pretty

The joints would fit pretty tight. But I guess I'd use anti-seize when slipping the pieces together.

When I've had joints that

When I've had joints that were loose or showed evidence of leaking, I've put them together with high temperature RTV sealant. You have to let it fully cure before running the engine.

Do no do this on a modern motor with Fuel Injection! It will ruin your oxygen sensor.

Thanks so much! So I will try

Thanks so much!

So I will try to fit everything together without any sealant and see if there are any leaks - and re-install with high temperature RTV sealant if there are leaks.

I just did this today

Over the last two days I am starting up a complete re-build . I bought new pipes (although stainless) and found that the cross over pipe didn't need any thing .One side between the header and the muffler, the pipes did not join up enough to cover the three
slots and even when the clamp was tightened I had a leak. I used RTV.
