I am planning on going with the procharger supercharger and am wondering what the recommended exhaust size is. Header back.... Also what is everyones opinion on mufflers. I want to have a nice deep sound similar to a V-* without the ricey casoo sound. In going with the supercharger I am trying to plan out my mods so that I am not buying bolt-ons and then replacing them later (waste of money), any suggestions of the order of mods I should go with. I'm thinking exhaust first and then a custom burned chip? ???
