I was thinking about buying the mac catback for my 02 gt but i heard that im going to need to buy new o2 sensors and my check engine light is going to be on...is this true

 

For a cat-back, no. For a un-catted mid-pipe, you'll need MIL (resistors that go in-between the rear O2 sensors and harness) or a programmer to turn them off.

 

Catback just bolts on and replaces the stock mufflers and makes the car louder thats it. I have MAC pro dumps, used to be the full catback and they sound great.

 

catback means everything on the backside of the catalytic converters to the tips, but does not include the catalytic converters.

you'll need MILS like spike said, will help keep the SES Light from coming on. I think you can also turn off the rear o2 sensors from a SCT Tuner, but not sure on that.

you'll like the ProChamber, they sound good.

 

so with the cat back i wont need nothing...but when i get the prochamber then i'll need to get them?

 

correct

 

okk thanks alot
