I've had one from LMC trucks in the past and had no problems. I was a little concerned just looking at the black and white drawing (without any real pictures), but I got a good product with a good fit and finish.
I can't say for one on the Hemi. I had a summit dual exhaust on my 99' ram with a 318. I know that the 318 is not the best sounding motor, however I had heard a good exhaust sound on several 318s. The fitment was very good and was a easy install, however the exhaust had no throaty sound to it and sounded very tinny. IMO sounded kind of cheap. From then on I either went with Magnaflow, or Flowmaster.
