Hey guys got a 2001 GV with V6 and wonderin what upgrades give better power and gas milage?

Airfilter,exhaust

Thinking customs downpipes

The only thing I'VE seen so far that WORK! Are custom intakes.

What about say a 2.5" cat back exhaust and a god muffler?

I'd suggest a good muffler and leave the pipes. The system is already pretty free flowing. There is such a thing as to big a pipe.

You could get high flow per cats and a high flow cat.  But then again this might be too much free flow.  :-/

Ya but I think a twin supercharger might be a little much.
Wasn't that thing rated at 1000 hp

There was a 1000+hp 4 banger on the discvery channel a while back. Honda I think it was.
They did some WORK to get that much power out of just 4cylinders!
Could you imagine a 1000+hp Sammy with still recognizble Suzuki engine components .

To much free flow would be a 3" exhaust u can not tell me that 1 7/8" exhaust is big enough for a 2.5 v6 with quad cams that like to breath.
