If I put the BBK Full-lenght headers and the o/r x-pipe (without cats) would this make my check engine light turn on from the O2 sensor? If so is there a way to make it not come on?

 

Yes O/R Pipe makes Check Engine Light come on. Buy MIL Elimantors and you wont have this problem

 

so the M.I.L. eliminator will make it work!

 

yes. OR if you have a chip (Diablo Predaor, SCT) you can use that to turn off the rear 02 sensors.

 

if I have my car tuned would that turn it off or do I need the new chip?

 

Like a dyno tune? Idk if they can turn off the 02 sensors from a dyno tune i think it really depends on the software they use... Cheap solution would be MIL Eliminators
MILS - $59-$69
Handheld Tuner - $340-$410
Dyno Tune - $70+

 

you need extensions also.

 

What are you talking about?

 

for lt headers you need 02 extensions. is there a difference between full length headers and lt haeders?

 

true didnt even see that. No theres no difference except the name. Long Tube = Full Length
