I looked into getting them once as I practically live next door to JBA. Know that if you do get them and don't like them, it would be expensive to remove them as they are welded on at the entrance to the catalytic converters. Moreover, after the exhaust manifolds are cut away from the cats, the opening has to be flared for a proper weld.
So, basically, if you don't like the sound, and want to go back, you'd probably have to buy new exhaust manifolds and the first set of cats.

What I know of the Doug Thorley's is you are taking your truck out of emission standards, hence the O2 simulator. Which is fine if your state doesn't inspect for that.

I do have JBA's catback (18" Magnaflow muffler) taking up space on the garage floor. To me, it sounds like $hit, but I'm old school.
