Off-road exhaust = NO check engine Light??
I just had the Mac Prochamber Hipe and Mac cat backs installed yesterday... Love the sound..although kinda loud. Anyway I drove it around quite a bit after getting it on, Id say about 60=70 miles and The "check Engine" light hasnt come on. I even ordered Mil Eliminators thinking I would need them for that. Anyone?

I put the mac O/R prochamber on mine and nevwer got a check engine light. I dont think it "HAS TO" come on, just the fact that it may come on.

The CEL won't always come on right away. Sometimes it will be immediately, sometimes in a few hours, days, weeks, etc. You will probably want to put the MIL's on anyways, so this way if the CEL does go on you will know it's most likely not due to the o/r pipe.

I've had my off-road X-pipe, and Flowmaster cat-backs on for nearly 2yrs now, and still no CEL..... I did get a CEL at first, but after reading the OBDII code, i had a bad O2 sensor. But after further inspection, I pinched the wireharness between the block and tranny when I did my clutch swap... Repaired it, and cleared the computers memory, and the CEL has never come back on after that..

that is because on the 94-95 models the o2 sensors are before the cats and read the same.
