I need to fit a new exhaust gasket to barrel when I put it all together, its a standard cast type fitment. When I presented a 42mm copper gasket, it masked quite a lot of the exhaust track and port so I need to source something with a bigger hole. Will it be OK to get a fibre item and then trim it to shape or is there a better option as I’m sure I can not be the only person who has had this problem.

I tend to trim the actual copper gasket with an electric band file- takes a few seconds and if you hold the gasket in a vice, doesn't distort it.

is the gasket the "big bore" type.........these have a larger id than the regular ones?

Trouble with the fibre gaskits is they can split when you take the exhaust off, which is fine when your at home but not very good at the side of the road. i made my own out of copper sheet in the end, just make sure you have a flat exhaust flange [thier not usully flat], a vice and a b@5t@rd file works a treat .

Use this...it's all you need..

Thanks for the info Guys.
It was a big bore spec gasket however it was still too small a hole for my exhaust port and manifold. I will get a new one and try and file it out or use my Dremel to fine tune but TBH I was unsure if it was a sold piece of copper so that i could be able to do this. If this fails I think I will get some gasket paper and cut one out.

Or these, I do....but go brittle after pronged use
