Dynomax Super Turbos. Got a good sound and not much drone. Sound good but too quiet for me so I ended up getting cutouts. Bear in mind I used to have straight pipes so yeah there's a big difference.

 

guys, i fixed the drone just by moving the dump to right behind the rear axle. I found some old exhuast tubing off a 99+ truck and just cut if right where it started to come abck down behind the rear axle. I put a dump there and just welded everything up and no more drone at all when driving! Its exactly VERY quiet now!!!

so anyone with drone issue, just move the dumo back as far as you can and you should be fine.. mine dumped about 3 ft before the rear axle at first and the drone sukked inside the cab
