Howdy All:

I would have asked this in the other post but it turned into a "My Daddy is better than your Daddy" contest.

That said, I am new to this site and a new 2001 Grand Prix GT owner. Well actually my wife's new car. It is a 3.8 NA.

Wife took it on recent 500+ mile trip and got 31MPG ave. To me very impressive milage. Is it possible to improve on that?

Questions are>
1-Will headers give a viable increase in MPG? That is, one that is worth effort and cost?

2-Same question about Tuner. And are we talking a chip or programer or something that requires operator inputed variables?

3-Looked at a couple of U-Tube delete options, complete down pipe replacement and just the bend replacement. Would and which one would be best option for improvement?

4-Do Not wish to remove resonator (Don't even go there!)

Thanks all for your responses.

Later Robert
