Small exhaust and small IC does not lose efficiency and volume? I am confused...
Silly me, crd want to change mark's IC just for the hell of it lol - jim really has no idea haha, what a joke huh!
Why would you run a stock IC when making 350awkw+ which is a walk in the park with his setup? My 1st gtr had a 70mm making 365awkw and at the time I was advised to upgrade to keep temp down. I don't make things up nor am I computer warrior, I always talk of personal experience.
