Hey every one Im new here and just bought a 02 impala with the 3.4 V6 I was wondering what are some good upgrades to do to see more power from my impala. Also ive been looking into a supercharger or turbo. What modifications would i have to do to get one in. Anything to the drivline? Thanks in advance.

the most common ways for these cars to get some more juice is a Fender Well Intake, 180* T-stat, u-bend delete, dual exhaust, ported manifolds, or you could also find a 3500 and do a whole top swap. theres more too, ill post more when i get more time.

Is there any kits for a cat back exhuast for my impala. If not would a performance muffler do the same thing? Thanks in advance

there are a couple kits for the w-bodys. i personally have the SLP brand dual catback. there is also the GM Performance Parts (GMPP) brand. i paid around $450 for mine. you could also go to a good exhaust shop and have them make you one. you want to make sure they use mandrel bends though and not crushed pipe. that crush method is just as restrictive, if not more so, as the factory set up.
check these out:

go on the left hand side of the site and click on Exhaust. then click 00+ Monte Carlo and 97-03 Grand Prix. they have the ported exhaust manifolds there.

those are all cat-back kits

and thats pretty much your whole exhaust system opened up.

Would replacing the throttle body and intake manifold give me more power? How hard would it be to replace these items? Also how hard would it be to drop in a super charger? Thanks in advance.

supercharger? i dont know. i do know that there are a couple turbos out there for the 3400, and yes with the correct supporting mods, a throttle body and intake manifold will see results

an example of supporting mods would be if you get a CAI or FWI, then you should also open up your exhuast. you have all that air going into the engine, so you should have a way for it to get out.

check out the parts websites list and go to the ones toward the bottom which are aimed at w-body impalas. for the 3400, you may have to search under grand am on some of those sites, but as far as suspension and things like that, impala or grand prix are your best bet. they have all kinds of performance components such as turbos, cams, downpipes, pcms, etc...
