Are you going to get LT headers too? because i don't think it is worth it to just get an ORY unless you get headers too. If you want LT headers and an ORY and of our sponsons have them.

Just a ORY for now.

I have one made by Bassani it is stainless steel and well made. Thunder Racing carries it. Here is the link http://www.thunderracing.com/catalog...&vid=3&pcid=99 . I may be getting rid of mine soon so if you want it we can talk.

Killer, I don't think yours will work for him. The manifolds changed in 2000 and he has the manifolds used in 98-99.

RDS, do what you want man. I went with bassani ory on 2002 manifolds and love every minute of it. I enjoyed that more that my kooks LT headers I have on now.

He can have my manifolds too. I'll even throw in some O2 sims that I don't need anymore because I have HP tuners. Let me know and we can work out a price if you are interested.

BTW, the reason I'm considering selling these is that I have a really big cam in the engine now and the exhaust manifolds are severely hurting my performance due to the amount of overlap that the cam has. So I need to step up to Long tube headers. But on a less radical or stock setup they worked surpisingly well. Here is my dyno printout with the mods below before I swaped cams and gears:
