Have to get new exhaust, help/opinions

Hats off to the cop for having you put some mufflers on

Never heard a completely straight piped gas truck that was even close to sounding good

They were mainly my choice because I just wanted it to be as loud as it possibly could without cutting it off (talk about sounding like shit), I agree with you a good muffler does have way better sound I just wish I could find one to match the volume of straights with the sound of the muffler :(

Maybe this can help a little better. It's Not a NBS, and I had my cats on but this was my 6.2 with a single straight and then a 15x5 round case sportsman 3.5" in/out borla XR-1. It was a little quieter until WOT. Then it was as loud as my straight damn near.

I forgot about you having that setup, sounded damn good Jimmy. Is that a duramax tail section?
 
and im sure it sounds like complete fucking shit, and you lost proformance, true duals are garbage, why do you think proformance guys run x pipes? because they like trying to make a big x fit under the car?
Only homos try to balance out exhaust pressure from both sides of the motor
