Single or Dual
 
OKAY! So, I have always been taught true duals are the way to go. I had a 2001 5.9 liter and I went dual 3 inch and lost torque for sure. I figured i went too big, and that motor wasn't very fast. So this motor is stronger, so I figure if I go dual 2 1/2 with x pipe ill be fine. Here lately though, I've read if I go single it will be more beneficial with power and torque. Any opinions on this? If u think single then how big? Thanks!

The stock system is 2.5 for a reason

if you are going with mild mods I'd put a full 3" single on there. if you have to have the dual tailpipe look then go with a single in - dual out muffler.

how modded are you now Mike? how much advanced will you be modding. If you are lightly modded I would change the Y pipe...run a single 3" pipe to a 3" si/so muffler. I have never been a fan of si/do mufflers (just preference though), with that said, I've taken that same si/do muffler and flipped it...so I'm true dualing it all the way to the muffler, then going with a single out... I'm different, don't do what i did unless you go into heavy mods (or use smaller inlets)

the stock system is inefficient to begin with (see y pipe)... stockwise, they built this for emissions and performance wasn't top priority... that's why with even an upgrade to a terrible muffler (flowmaster), performance improves..

I have K&N, Superchips, and single in dual out Flowmaster. I'm gonna get the Dynatech Supermaxx system, then was gonna dual it out, but I think I may just stick single

I did a new Y-Pipe...pretty cheap and effective, left the single 3" into a dual outlet Magnaflow...check it out for some ideas....250 bucks total spent.

id prolly go with duals just cuz they look saweeeeet

One way to make duals more effective is to go down a 1/4" in the pipe size.

One way to get the dual look without losing torque is to go with a single in / dual out muffler and two tailpipes.

With a single exhaust, use a muffler with a 2.5" inlet and outlet. You can go to a 3" tip for the look.
