Re: Through frame exhaust, how do I do it?
I sorat got that idea from how Corvettes route their exhaust piping back.
I figure you need to determine where your head pipe starts, in relationship to the distance to the muffler.
When you decide that, then you can start measuring where the area you need to modify lies.
I thought that round steel piping with ".xxx" wall thickness is somewhat necessary to provide strength and hole sizing.
