has anyone swapped their asm headers for the pacesetters? i now have the asm but with the radix and my engine mods i think the bigger primaries and collectors on the pacesetters would be worth some xtra power.just wondering if anyone else has done this?i have someone to buy the asm headers so i wouldnt be out any money.

 

The info i've read says they both have 1.75 inch primary tubes. I spoke to one of the guys at AS&M and he said that they had tested larger collector diameters on a RADIX equipped Chevy p/u, but it didn't improve dyno numbers.

 

the primaries on asm are 1.625 and i havent talked to asm about it but all i no is on most blown engines you want the biggest you can get.when i purchased the asm they were the only long tubes on the market.they are great quality but i just want more .unfortunatly that is my life story.but thanks for the reply.

 

Talk to texas terminator on the site. I know he just swapped from ASM's to Pacesetters, cause I bought his ASM's. Not sure of his setup though.

 

I just looked on AS&M's website, and it lists their headers for 99 to 05 Sierra/Silverado as having 1.75 inch primaries. From what i've read the Pacesetters, Dynatechs, Stainless
Works, and AS&M all have the same diameter primary tubes.

 

mcklusky your are correct sir.i took someone elses word that they were 1.625 and never checked them till tonight.so maybe its not worth the work after all.thanksagain
