well, iam going against what the reputable summit tech advised me on, and buying some ASM long tube headers. other than tybrne, wheres a good place to buy these at. nothing against tybrne at all(his costomer service is A+), ill actually prbably get them from him, i just want to see my options(distance from me, pricing, etc)

ps yes i see all the sponsors to the right, but there is just soo manyyy

 

I know futral motorsports sells them.

 

Thunderracing carries ASMs too.

 

i would get them from Tom. he is a great guy to deal with.

 

ok, iam on thunderracing right now. i can get them for 720. thats 60 less than futrell and tybrne. ill give these guys a try with my business. anyways, is the part number 12-20410 the right set of headers to get. it says 99-01, iam just double checking. iam pretty sure those are the ones that will fit my 04 Silverado SS though. thanks guys

 

You can get them from ASM too.

 

Thunder Racing is excellent to do business with.

 

yea iam just confused at their website. on thunderracing.com the asm headers say 1999-2001 4.8, 5.3 and 6.0L. i was just on ASMs actual home website, and there i have 2 different choices as to which headers to get. thunderracing only has the 99-01s. this is just no good. i need the 02-04 headers.

 

Is it the egr/no egr thing?

 

Call ASM and see what is up and get a part number for your application then call Thunder. I agree, they are great to deal with and so is TByrne-can't go wrong with either as far as service goes. But it has always been my experience that if there is a fitment or application question it is always best to talk with the manufacturer to get the scoop firsthand.
