I believe I already know the answer here but figured id pose it to fellow owners. I want more power than my V6 currently offers. Can you get noticible hp and acceleration gains with upgrades or would it be more cost efficent to sell it and by gt or better? I already am replacing exhaust, but was wondering if that and few other upgrades would be noticible or am I better off upgrading car? Not looking to break records. Just want some pep.
