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.

Sounds perfect, would like to hear this on a 5.3. Bad ass truck by the way, what size lift?

I forgot about you having that setup, sounded damn good Jimmy. Is that a duramax tail section?
 
Put cats on and gut flowmaster 40s keep your true duals or just put cats on I got true dual straights on my 5.3 Z72 2.5 pipin with 4inch tips
 
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
