Re: how much power will these upgrades give

intake and full exhaust will give you about 5-10rwhp.......10 is being real generous

Re: how much power will these upgrades give

It is very difficult to give exact numbers and most places do not publish "dyno proven gains" on V6 applications because the numbers tend to be depressingly low for the money spent; however, if you do all that AND have a good tune, there is no reason why you couldn't see 15+ rwhp gain.
(Also, would this be an off-road exhaust set-up?)

An "off-road" or cat-less set-up is best for power but not sure what your state standards are on that.

Re: how much power will these upgrades give

No cats on a V6 Sounds like crap !!!! V6 are a even fire engine go true dual no cross over needed. Get a SCT x-cal tuner to see a bit more power from your mods

I'll agree with that. The mufflers are the main musical instrument.
