Exhaust is all stock with flowmasters welded in. Can I bolt in MAC o/r prochamber with the stock cat-back..any issues with this setup? Also, where are the O2 sensors on the exhaust? Are they on the midpipe itself or what? Will I need the MIL eliminators with the prochamber?

 

Yeah it should fit rite up. Although if u put the Elimanitors in they usually don't always work for awhile. A tune will get rid of the check engine light if you get rid of the emissions check within the vehicle. I bought them and they worked for two months then my check engine light kept coming on. I got a tune in june and ever since then I haven't had any problems. Also, the 0 2 sensors are located in the x pipe towards the front of the pipe and the back of the x pipe. But it will work out at least for awhile.

 

O/R pipe yes youll need em...maybe with highflow cats. yes it bolts to stock manifolds and catbacks. mil elims not working is a possibility, mine have worked fine since i put em in no probs yet, but i do know a couple guys around here whose CEL's come on if they turn too hard or w/e
