has anybody seen dyno runs in real life on asm headers? i dont think i have ever heard what they pull, dont know many people who have them on thier trucks, i think it would be great to know to compare it. if u got the money, by all means spend it. i know i would if i had it, but hamms were just so much cheaper

 

I don't know if it's to late to order but the price is going up after the first of the year. I ordered mine in November. John has a 4 week backorder now. I should be hearing from him soon for shipping.
