And to all of the comments about state inspections, those don't happen everywhere. I live about 6 miles outside the Chicago metro area, and we don't have emission inspections here. That happens just inside the metro area. Of course, the rules are probably different by state....
Yep...a nice rumble. I’m in an inspection required state (NC), unless it’s a certain age. I definitely could not substitute a glass pass for a catalytic converter. But probably could substitute for the muffler part of the system..
