Re: dual exhaust system
I'm sure you could get it to fit, if you are talking duals for an F150 4WD. Some pipe will likely have to be cut/shortened. And you need to see how it is routed, not much room around the auto tranny/tcase in a '94 Bronco.
Duals are not ideal if you are interested in keeping torque. If you have a stock 351, the target pipe size (single) is 2.5-3". This size is even good if modified, as long as we aren't talking any high HP/higher RPM motor. So with duals (true duals), what pipe size would you need to keep torque? Dual 2.5-3" pipes, which are typically advertised, would be overkill, and you would feel it in your bottom end. [img]images/graemlins/frown.gif[/img]
Even dual 2.25", if you do the math on internal area, comes out way more than a single 3" pipe.
So, from a cool standpoint, you need dual 3" pipes to look good, but it sure won't perform as well.
