So my muffler guy who does the duals for v6 mustangs for the local dealer said i didnt need an x or h pipe and that i should run em straight back. Whats your thoughts?

you will lose power and sound doin straight pipes. if thats what he thinks, find a new guy.

h pipe for sound, x pipe for power.

+1, you need some kind of balancer pipe, H or X.

I think you should read my sticky on "Cross Over Explained"

Especially the section on 6cly engines.

here is my install of the H pipe, it's not hard to do, you just have to find the right person to do the job right.

I had exactly this same issue arise when I was in the process of installing my duals about a month ago. The guys at my local Midas wanted to run straights, but after hearing from Professor Wizard and checking out gregbe's site, I was convinced that the h-pipe was the way to go.

I ended up purchasing two T-pipes from ebay which the guys at Midas welded together to make an H (l- + -l = H). I am very pleased with my set-up, although I don't have any basis for comparison to either x or straights.

Feel free to PM me if you have any specific questions.

I had straight dual magnaflows and it didnt sound good at all.... it sounded like it was just blowing out air. So i upgraded to an h and it has some rumble but i still think i want some headers or some flowmasters
