don't replace true duals with a si/do.
thats a step backward.

 

yeah i agree. i mean si/do aren't bad at all, but if you spent the money on butting up to those manifolds, you should keep it lol!

 

I know, I will try and find a good deal on two separate mufflers. I also found a cheap X-pipe that I could just put on and then have the mufflers come off of it. How much of a difference would it make I wonder if the mufflers were staggered? And can they be mounted upside down, like flipped to get the inlet and outlet in line with the pipes? Should sound pretty awesome either way. I'm looking forward to working on it.I think it will be a fun project as I've never done it before.
