@James - I wasn't quite sure if would really make much of a difference, either, but I figured it would help a little more than just 2 straight mufflers side by side.

@Beaner - Does changing the piping size affect the sound at all, or did you do it purely for better flow? I still have the exhaust clips you sent me, thanks for those. That is what made me really consider doing this type of setup.

I suppose that if I end up doing this setup and don't like qualities of the muffler I can always just switch the muffler out with a different one.
