Johnrv4,
I can't advise you on the cam plate dilema as I have ordered the 230/605 and changed my mind to the 250/650 even before the package has arrived. But without the experience of increased fueling in my Ram, I will say that you can go with a cheap alternative and upgrade with your exaust side. Here's what I did:
Keep in mind that I have torches and welders so this was fairly easy for me.
Removed the exaust starting at the cat. I gutted the cat by putting it on end on a block of wood and driving a steel stake through it for a half hour until the inner contents broke up enough to fall out. It was reinstalled.
I then slipped in a piece of 4" exhaust tubbing, the Walker (4" in and out) muffler, a 4"-5" adapter, 5" elbow, clamps and a tip from a Kenworth. Hanger were modified and welded on to support the system.
I went with 5" out from the muffler because it was what the truck shop had, not 4". No regrets though... it sounds awesome! The walker was only 90 bucks at a Napa parts store (Not all napa's have them, just the super Napa's in my area. ) I put the Walker 22572 on and as I just stated, it's a 4" in and out. I believe the 3" version is the 21471. . It sounds great too and is only about 60 bucks. Also, it would be cheaper to go with 4" out or keep the 3" existing system from the muffler back.
If you're planning to stay under 375hp or so, some of the posts from the "Gods" of diesel say that you wont need 4" all the way out for increased power but I think it would help with keeping things cool. Do a search on mufflers and you will come up with some killer info to aid in making your decisions.
Good luck,
Steve.
