High flow cats and a pulley. Axle back does not ad any power.
Don't forget probably the easiest way-if you don't do meth, than add race gas or e85 to get to 95 octane atleast. That is good for up to 20 hp alone. So if you do high flow cats, pulley and race gas even without a tune you are at 30-40hp more.
That was back in 08, I'll try to dig out that dyno for you. And BTW you ain't raining on my parade in any way
