I disagree on that... true dual will open up the exhaust and let the motor produce as much hp as it can. the more air flow, the more HP it can make. it all depends on what your after and what rpm range you use your motor.

RE: exhaust
my advice? Go with Gibson. I started out with a 2.75" 2 chamber flowmaster system. I also don't like the duel look because of the exhaust hanger issued that was previously mentioned... so I had a turn down put on it.... SOUNDED GREAT... loud and deep at idle... and tough at WOT... 0 performance gain. I now have a 3" Gibson single pipe set up and it has given me a more power and better fuel mileage... not NEAR as loud. Good rumble at idle and nice deep throaty sound up to about 2250 RPM... quiets down a bit after that... but I have enjoyed it as an exhaust mod.

I don't mean to disagree but if I am right, someone correct me if I'm wrong, newer model trucks need a certain amount of backpressure to run correctly. If there is not enough then the performance is hurt.

if your truck is a 4x4 or used for hauling of any kind, you'd want the backpressure to help build more torque (smaller outs on the exhaust). if your after high end hp, then open it up.
my truck is sorta in the middle right now... the motor breaths really well thru 5k rpms... but how often does it see it? ... (ok, often) but it's the low end torque that provides the most benifit in terms of off the line performance and fuel economy. I'm looking for a new intake (kegger) that is stock so I can bring back some low end tq and hopefully improve on the 14 mpg hiway I currently get.
one other thing... you can change how a motor performs by changing the air filter as well... just like the exhaust. open the exhaust too much, loose low end torque. open the intake side too much, same thing. (I have 2 filters to mess with this is how I know...) [sm=alcoholic.gif]
