i heard good things about it , so I'm gonna order it soon. I have a question though regarding the instal. Will i get the check engine , with The MAC H??
and is the instal easy and a direct fit??
thank you
You'll get the check engine light on if you order the mac o/r h-pipe yeah... you'll need to order the MIL eliminators which attach to the co2 sensors and stop them from throwing the code...
They're a snap to install though. I think I ordered mine from dallas mustang but that was many years ago... i'm sure you can find em on a few different sponsored sites.
Well I think you answered your own question with that....
They do still work by telling the ECU to throw the code that your cats are bad (since you have no cats) but that cancels that out. So in effect yes, they are worthless because they're always saying your cats are bad.
