Exhaust gasket replacement

[Guest]

I recently removed, refinished and replaced my MAC 4-1 system. There were copper crush gaskets in there that I reused. They were crushed where the pipes contacted but other than that appeared to be OK. Should I be reordering new ones anyway, any opinions?

If they seal you are good. If not, get new ones.

You can usually re-use them a time or two, but you're supposed to replace them every time.

So if you don't replace them, you take a chance of one or more leaking, and the chance increases the more times they've been used.

Fortunately, an exhaust leak from a crushed-too-many-times crush gasket isn't one of life's more serious problems. It just makes a little ticking noise, but won't really hurt anything. If you've got somewhere to be, go anyway.

I always try to keep some of these gaskets "in stock".

The Suzuki exhaust gaskets are sort of a paper-ish stuff with steel around the outside and inside, but the copper ones work OK with aftermarket exhausts.

The copper gaskets aren't thick enough with a stock exhaust -- guess how I learned this...

Thanks folks-I guess I'll leave them in place 'til I know better.

I've reused mine MANY times. No leaks
