You may already know this but I sure didn't. I had my exhaust installed at a local muffler shop last week. The first thing the owner said when he saw the system was "Hey, these are MagnaFlow mufflers." He walked me over to some shelves of MagnaFlow mufflers and pulled out identical pieces and tips.

He also chuckled after learning of the selling price for Comptech's system; he claimed good shops can create identical systems for less than half the price.

Oh well.
