I run the xtreme series s/i d/o. It was nice, no drone and it was loud when you step on it. Then i put the headers on and took off the cats and it a totally different sound. It has an annoying rasp around 1800 rpms. Doing 70 is madning on long trips. IMO if you do this one leave the cats on.

My vote goes to Quickflow, they sound great and are made right here in LA.

i like my 40 series flowmaster.... L/T's, 3" custom Y, no cats, si/do muffler with turn downs. the inlet of the muffler is even with the back of the cab. yes, its loud, yes it drones, yes is does sound good, though. throaty like a muscle car. its a little raspy right around 2500-3500 rpm's

I run Pacesetter LT's dual into MAC mufflers. I really like them. I like them because no one else around here has them. Sounds great.
