x and h pipes

I would disagree with that statement. I wnet from 2.25" dual exhaust with straight through glass pak mufflers to a 2.5" system with an x-pipe and Flowmaster mufflers.

By the butt dyno I did not feel any difference in power but the sound level is low at cruise with no interior resonance. This is an ~ 370 HP 360.

I just can't see a 20-25 ft-lb increase in torque by just adding the x-pipe.

Just going on the 3 or 4 articles in the Mopar mags and Hot Rod rag, that I've read - and personal experience. (dyno pulls, et's slips). I'll try to find the articles, and post . Of course alot of other factors have to be considered - horsepower, size of complete exhaust. tailpipes, etc, etc. If you have a lot of bottled up horsepower/torque, there should be a noticable difference. :-D:-D
