I am getting set to modify the exahust system. The question I have is this Magnaflow product. This muffler has an internal cross chamber that appears to work like a X-pipe. What I was thinking was to run two pipes after the cats, removing the Y section, and connecting to this muffler (duel input, duel output) without a X-pipe. Then I planned to use the stock pipes after the muffler. Will this muffler act like a X-pipe? The other alternative is to do something like what vettegirl did with seperate mufflers. Any information would be helpful.
