Pypes Turbo Pro

I have to confess. I found a place to put it and installed it but a local muffler shop sells the stainless kit with the band clamps. They say they install them on the new Mustangs, Camaros, and Challengers because they are drone monsters with upgraded exhaust. They sell mid pipes with them already welded in. Mines being in the tail pipe works fine.
You didn't have to mess around with altering the length to match the resonant frequency?
