RE: Glasspacks
If you have cats they wont be that loud.
I have ONE on my 4.3 and have had "turbo tubes" ( kinda like glasspacks but without the fiberglass) on a 350 v8 SBC, as long as you run the cat it will be alot quieter then you think. Wont even sound like a glasspack honestly.

I don't know what you are expecting to gain from running true dual exhaust... Other than the fact that it'll sound like dualing 3 cylinder engines... Which in my opinion, doesn't sound good at all. You can get the same gains with a properly sized single exhaust. You need to take into account what you have already done to your engine, etc as well as determine what you want out of the whole package.

RE: Glasspacks
So in short, whats the single best (besides headers) upgrade for the exhaust? (2nd gen)
1/4" bigger piping
cutting out the cat
replacing the muffler
modding the bends
im sure theres more.

RE: Glasspacks
im sure u could run two 2" pipes side bye side all the way down the passangers side with the glass packs off set. the only other problem might be the cats. and a cross over will be nessasary. i ran true duals this way on my 98 silverado with dual thrush glass packs and only a 1 1/4 cross over. sounded mean as all. i also had the 21" long 3" round slash cut chrome tips. i plan on trying this on my wifes 97!

Yeah, that's because it's a big truck and 21" 3" tips look good. I don't even think you could run 21" long tips on a blazer without them sticking out unless you ran them through the back, which would be pointless because you'd probably see like 2 inches of it. Can't you do a crossover on the Blazer by the rear axle?

alright i was trying to explan to him what i did on another vehicle just trying to give some ideas. not specifications im sure he will see that he needs like a 12" long tip and thats even if he wants them. But the old V8 sure did sound good.[sm=gears.gif]
