Actually, I run the two 5.9 trucks a lot because I let the boys drive them. I figure if somebody is going to do something stupid to destroy a engine, it might as well be a 5.9... good excuse for a Picco transplant!

They actually do make a lot of [link=http://www.youtube.com/watch?v=tVCLxpFJmTs]low end[/link] on the stock pipe. But they suck bad when you try to get rpm out of them and to get top end out of them, they get so stinking hot as you noted. The XL in that video is stock. pipe and all, well, it was at that time. It runs okay, but it has that huge dead spot in the upper rpm. The CEN pipe might give it more low end punch, its all good though, as long as we are having fun. Bud
