I have a 2002 GP GT n/a. Next week I plan on replacing the u-bend with the downstream o2 sensor with a straight pipe from ZZ Performance. Will I see anything as far as increase in performance or gas mileage. Is this a worthwhile mod? I have a cold air induction with a Spectre air filter right now. The GP has about 80k.

yeah its worthwhile. itll free up some hp..not MUCH but a little. and youll probably see an increase in gas mileage.

Depending on what you really want todo in the future, it might be better to just buy a 3in downpipe. That will give more performance and maybe 1 mpgs improvment. Really its letting the car breath and be happy.
But if you dont want to go further, a ubend delete will still help the car breath more.

it's 100% necessary

Don't buy it from zzp.. Just save your money and go to a local shop that'll do it for all of 15-20 bucks
