O/R X with stock manifolds is ungodly loud. Ive got an O/R X with my bassani cb with deltaflow mufflers, and if i'm next to the wall on the interstate, and I punch the skinny pedal with my window down, it literally hurts my brain. ha
I would go LT w/ midpipe, that's what i'm doing with my setup soon. It cleans up the tone, and its not as overpowering.
