Hi. I am looking for some input.

I am converting from stock exhaust manifold with single exhaust to Fenton headers dual exhaust and glasspacks.
I plan to use the stock intake manifold and heat the manifold.

Has anyone used the exhaust heat to heat the intake manifold? I was wondering how that works compared
to the water method that Langdon shows on his website.

Does anyone have opinion on a particular glasspack muffler?

What diameter exhaust pipe do people recommend?

I am looking for a little exhaust rumble but I'm not looking for the 18 year old straight pipe no muffler sound. lol

Thanks guys.
Joe
