What exhust size?

OK, so i'm going the supercharger route with cams, new valves/springs etc. and i'm wondering what size exhust i should go for, i'm thinking 2 1/4" mandrel bent and a 4-2-1 extractor setip...

Would 4-1 be better for a supercharger? I like the idea of shitloads of torque so i'm leaning towards the 4-2-1 setup and the mugen style loop-back muffler and a single resonator in the middle to quieten it down a bit..

  • I've read 2.5 is better for forced induction.

    Check out the stainless Kamikazee 4-1 header. Very nice and by all accounts, a supercharger friendly version.
