Dwight,
At the time I found this one it was the only electronic one I could find. Cost was just under $500.00. I know of know others, sorry. If you'e running stock side pipes,(I'm assuming they are much like CR's then you are loosing as much as 45 ponies on the Dyno. Huge loss by the way. Headers didn't seem to make much difference, I did build customn header a couple of times and only gained about 3 HP, really wasn't worth the effort. The danger here is going to be on the headers. 1-7/8's seems to be about right 2" and the drop begins. I would call any of the main header builders, not that they make them but they can give you some real info, i.e., diameter, lenght etc. Hooker, Redman, among a few.

If you arent getting any "clunk" on take off, no wheel hop, both tires are leaving close or identical marks on take off, I assume your rear end is pretty close if not right on. Nothing lilke a good burn out about 20' long with new tires, stop in your tracks, get out and "read both patterns. They should be pretty much the same. This little test can tell you if both axles clutches are working in unison, that your diff. is actually locking up both tires, it will even show you if you have a slightly or greater bent axle. Lots of technology on a solid "burn out'.
Test,test,test!
Promise: If you have 380 RWHP now, new pipes done right will get you over 400-promise!
