well its been awhile since i posted i bought a 1997 Bravada about 8 months ago and love the thing i had my local muffler shop slap on a flow sound performance muffler just kind of cut off big ole one weld in cool soundin one i got a CAI sucks in some serious air i want a Throttle Body spacer any one know about these? and is it possible i can get a y pipe to make my truck have dual exhaust i like that look alot let me kno thanks.. AJ

First off....please stop asking 6 questions in one sentence......yeesh.

Don't bother with the y-pipe or the TB spacer. Neither of them wil net you anything.

the 4.3 v6 will loose performance with true duals. you may be able to get away with a split rear cat back. dont get a throttle body spacer. they do nothing to improve performance.

so.... how does true dual hurt the 4.3

not enough back pressure to perform properly. the furthest you should go on a mostly stock 4.3 is a 2.5in single exhaust.

now what if im running cams, lifters, intake, headers, and tuned? can i throw a dual on then

if your doing a fully built engine, then u could consider duals, but i still don't think you would take full advantage of them unless you are considering forced induction.

such as a supercharger or or turbo. how bout ram air?

forced induction is a supercharger or turbo, not ram air (doesn't create boost).

gotcha, well i guess i wont be needing the dual anytime soon then, but just out of curiosity, anyone know a good supercharger for the 4.3 vortec? been interested in one for a while now

vortech and powerdyne (i think thats it) make kits for the 96+ 4.3. if you have any specific questions about a supercharger on a 4.3, ask blazerSS (he has the vortech kit but he also built the engine first).
