is this true dual thing true?
It almost never happens (with any mod) that you get true a/b one change results that are well documented, too often other factors are in play too.
I'd love to see a true a/b comparison with dyno results of JUST changing from 2.5 to 3 true dauls with the SAME design, and with the distance one each side to the x exactly the same.
Folks, please remember too... it's damn hard to get the X dead center and the exact same distance from the collectors on an F-body. X pipes work great when they are set up like that (as you can easily do on a Vette) but not so hot when you have to have the x unequal lengths from the ends of the collectors.

I went from stock manifolds, two cats, single pipe over axle to SLP muffler (274hp/306ta) and swapped to Pacesetter LT's and a 3" x-setup dumped in front of the axle (282hp/318tq) and it didn't seem to make as big a difference as I was hoping. I'm now running a rebuilt motor with a few more goodies and I know that the 3" is overkill. It does sound really good though and I will be very reluctant to get rid of it for fear it just wont sound as good (IMO) with something else.... hehe..

am i the only person here who thinks that a dumped exhaust with little ground clearance is just f*cking hack? i think its absolutely disgusting to see the exhaust hanging so low under the car and i personally think dumps sound like any other 5.0 mustang on the road, lots of motor work done or not....if you're gonna do it, do it right, i have a 2.5" td setup tucked up in the factory location with long tubes and its no problem at all, so i can't fathom what everyone elses problem is

While this isn't exactly part of the debate (or I just didn't read it haha), but I think that 2.5" would sound a bit better than 3". That, and as mentioned, the aid in ground clearance.
EDIT: PS Why not an H-Pipe? Not as efficient, but it still helps equalize the pressure for better flow. My 86 Suburban I had one installed and I like how it sounded afterwards
Hell, people even do mini H-Pipes before the Y-Pipe on stock exhaust just to help out every little bit. Being poor myself, it'd be something I'd do lol
