May check with zzp about a set of mufflers that have the correct offset. In your opinion do you get more sound from the mufflers or the deletion of the resonator? My guess is the combination.
Unrelated but a bit of sound is gained from cutting the front off the air filter box. I had an opportunity to floor mine in a tunnel on the hwy w the box altered, to me it sounds wonderful.
