i just put a cattless downpipe and exaust on my suby and was wondering what problems i may run into i all ready did the o2 fix

 

Did you do any kind of Engine Management to go along with your new Downpipe & Exhaust? If not, then you are leaving power on the table. Actually not just Power, but you also could improve your MPG if you get a quality tune.

Otherwise, since you have an '02 you should be fine to run the car for a while. The '02's & '03's do not suffer the same kind of problems that the '04 plus models have due to Open Loop/Closed Loop tuning by the ECU.

 

time for a cobb ap!!

 

Sounds like it's time for you to get a Cobb Accessport.

 

+1 on EM! Once that goes in you'll really feel it.

 

+1 for Cobb AP
