: 94/95 Difference?

Hello,

I know people have talked about the Flowmaster downpipe and crossover. Everytime I have looked at it online it shows it's for a 95-98. Well, I have a 94. Why don't they include the 94 in that? What is so different about it that I can't use it on my 94? I'm going to hunt down Flowmaster's 800 number and see if I can call it from up here, but thought I'd come to the experts on the 6.5 first. I can get it from our local speed shop (I don't know if it's on back order or anything) for cheaper than I can get the exhaust guy I found can make it in stainless I think. I can get it in stainless made or get it from flowmaster in aluminized. Comments, suggestions or the differences?

Thanks!!
Jill

'92-93 would be better, with no CAT flange. 94-98 would have that flange but 99 would not. So, yes 94 and 95 same thing as far as exhausts.

Thanks Quantum, but I needed to know for the downpipe part only. We don't have a cat on the truck at all right now and have no plans to add one. :)

Well, I called Flowmaster and they didn't know if that would work or not. He did suggest that I call the dealer and see if the stock downpipe part numbers were the same for the 94 as they were for 95. The parts guy I spoke with said that their stock downpipe shows for 94-00. Now just to figure out if we want stainless or live with the aluminized for now and get stainless later on when this one gets holes in it.

Thanks for your help!

What I'm saying is that you'll have a flange on the downpipe '94-'00 aparently. If you have a flange bolting up to the stock downpipe right now(I'd assume yes) then you have nothing to worry about, but if you want it without the 4-bolt flange, you'll have to cut it off or buy a '92-'93 specific down pipe, which is how I went. Aluminized or chrome, they both look good, don't know about heat related aspects.Edited by: quantum mechanic
