Im about to have a 1275 built for supercharging (mercedes m45 blow through intercooled) and was wondering what the best exhaust size is.
My LCB manifold is 30mm o/d. Is this a bit small? 2 inch for main pipe? What mufflers will give the best balance between noise control and performance?
Is it advisable to get rid of the heart shape in the combustion chamber - im using 18cc forged omega pistons? Aiming for high 8s c/r
Is it worth dry decking? I want to do it right do it once.
I know I should trawl on here for hours cause its already here "somewhere" but Im hoping a couple of minutes from you smart people will put me on the right track quickly.
Cheers
