in a performance aspect i would go for some headers. cant really help you with the warrenty. and yes the exhaust manifolds are still very restrictive.
I have a mps Pully so I can put back on a 3.8 and I still have my factory PCM which I can install as well in a matter of a few mins.

But yes you are correct I will have to ask my dealer if I can add headers, hell they flow better than the crap stocks so a person is only making the car breath better any how. I don't see how headers could cause issues over stock any how.

go figure .

So besides headers what other things can I do.
