I don't kno exactly depends on what brands you go with and gears give u acceleration but don't give u more horsepower but u would definately feel an increase in throttle response
Yea I have heddman hustlers 1 3/4 square exhaust ports and 3" collectors on them call summit racing they can hook u up with all the brands they carry sizes and prices
When u guys racing?? would lik to check it out if im around and its all about who is gettin there power to the ground in my opinion. . Good luck 2 both of u
Spools and slip differentials What does each do? And which brands do you guys recommend? I want to work on my rearend for the winter so please help. . .thanks
