As you know, the Mach 1 has a "traction bar"(i didnt make this up, my friends dad did). aka Sub frames - the boxy bar that was bolted to the frame (I coulda sworn it was welded..)..

Anyway, he got the roush stage 3 kit with side exhaust, and those were removed to fit the exhaust, should he be good without them, or should he find a custom piping shop to screw around with it?

dont hold me to it but it shoud be fine just like that but just in case ask someone at a custom piping shop about it

its better to have the subframes, but you will be fine without it. I just put mine on the other day.
