Re: [DML] refinishing muffler and negatives with no cat?

[Martin Gutkowski <webmaster@xxxx>]

Hi Andy

If you have a look at this article I wrote about exhaust gaskets I went into some detail
on removing the exhaust. Taking the cat out is quite difficult because you have to remove
the crossover pipe from the manifolds in order to access the upper right cat mounting
nut.

As to refinishing the silencer, over here you can buy high temperature paint in a silver
shade - I did my heat stove with it till I decided to leave it out anyway... I can't
vouch for its lifespan though. I believe there's a ceramic coating process but I can't
see the point *personally*.
