Default Single vs dual exhaust

Other than looks is there a big difference? For quite a while now I've wanted to have a dual exhaust, but instead of having it exit out behind each rear tire as mine does now I've wanted to have it exit out in front of each tire. I realized this wont work or at least I don't think it will since the gas tank appears to be in the way on the drivers side. Yet I could do a single exhaust out of the passenger side in front of the rear wheel. The reason I'm considering doing this is the day before my transmission died my exhaust hanger right before the tip on the drivers side broke off and broke a chunk of the pipe out with it. I was hoping I could just get that short piece of pipe replaced, but I'm sure the shop will probably want to redo that whole side from the muffler back. I really like how it looks now, but I'm wondering if it's the time to try out the setup I've wanted for a while with it in front of the tires. Right now I have 2.25" pipes. If I go single exhaust I'd go with a single 3" pipe. I'd also have the change my muffler from my si/do to a si/so. Since I don't have true duals and only a si/do muffler is there any performance difference between a single and dual exhaust? Or is it just looks? Any preference on the looks of either setup? I'm also considering going to a Flowmaster 10 series if I do this instead of the 40 series I have now. I'm undecided on if I want it that loud though.


I'm also tempted to just weld it back up where it broke as since the piece it ripped out of the pipe about the size of a half dollar is still attached to the hanger. I think I could weld it back decently enough. I can't decide if that's what I want to do or if I want to do it right.

unless its a race truck, you wont notice power wise either way......you can keep your si/do and have 2 pipes in front of the pass rear tire...heres my old setup, now i just have a si/do 10

Hey Dakota, why does your rig sound like that? It sounds a bit odd...or at least I haven't heard something like that before. What muffler are you running?

Ya that is why. I'm running dual straight pipes w/ no cat as well. Love the sound of it. If you were gunna go straight pipes or even straight pipes after the cat then the whole tips coming out in front of the rear tires shouldnt be all that had at all. Any exhaust shop will do it fairly cheap.

FWIW I run a single 3" out the side before the tire on my Dakota, at one point I had it split into dual 2 1/2" behind each tire and HATED it, sounded awful, went back to the single 3" side exit and I'm happy again.

Here's a sound clip, muffler is an Aero Turbine 3030.
