I just got BBK LT's and an Off-Road H-Pipe for my 2002 GT. Do I need MIL Eliminators for it?

 

Yes you need them unless you have a tuner to turn off the rear 02`s.

 

Yes, you may get away with no check engine light for a while, but it will eventually turn on. If you don't have a programmer to turn off your o2's, you'll need MIL eliminators. You can go to www.mileliminatorsonline.com to get some. They actually work.

 

Do I need O2 extenders as well

 

I needed them. Some say they needed them and some say they didn`t. Just get them to be safe. You can always return them if you don`t use them.
