how do u like the headers... did u gain some torque down low... in know i'll nget upper rpm's, but i want some down low...

 

I noticed an improvement driving around town, it pulled better at mid throttle than with the stock manifolds. Also on uphills the truck was able to keep its gear instead of downshifting at the first chance. It wasn't a night and day difference but it definitely felt better.

You will need a tune after the headers, then it'll be more noticeable.
