Headers, how much gain??

[becker87]

Did you get 1 7/8 or 1 5/8? I'm guessing 1 7/8 for the price.

1 7/8 I do believe! Had an issue with header bolts loosening right away but the problem has since been solved by using lock washers.

a tune isnt need for longtubes,but with a tune youll see even a bigger gain.If you do this setup longtubes,ORY=offroad ypipe,highflow cat or no cat with a spintech muffler dumped,and K&n filter without a tune you should see an easy 25hp to the wheels thats about 40hp to the flywheel and with a tune depending on which company tunes it 35hp to the flywheel maybe even more.Plus a TR220 cam you got yourself a fun truck.

Are you saying the tune adds 35 at the flywheel on top of the untuned 40? Or losing 5 hp after tune? Also what kind of torque gains should a person expect to see from that setup you mentioned
