Just bought a heartthrob exhaust kit from autoanything.com. I got the muffler for less drone. Just a single muffler with a dual exit. Installation instructions were a joke. Once I took a grinder and hacked off the old exhaust I had to cut the mid-pipe to fit because the kit came ready for any bed/cabin combo which was stupid. I finally caved and had a shop put it all together and weld it together. Sounds decent. For about $250 not too bad of a kit.
