Very interesting sound... It'll be interesting to see how it sounds when it breaks in... I don't like the starting out "raspiness" But your driveby's were great sounding.

Did you just have the stock muffler removed, and this installed in it's place with a single outlet in the stock location?

Does anyone know if placing a Y after the PV is bad? If it effects performance etc.?

I'm thinking PV to a Y and dual outlets.
