Nope, The pipe after the muffler has no effect on the low end performance.
I am running a true duel system made out of a 07 exhaust with X-Pipe duel 14" Magnaflow knockoff's and 2 stock 07 tailpipes.

so if the pipe after the muffler has no effect on the performance that means i dont need the X Pipe right?

The X-Pipe goes in front of the mufflers, it is up to you if you want to run one or not.

2 1/2" at the muffler, 2 3/4" after the flange and 3" at the tips.

 

[time6is6money6]

so from the muffler to the tip is 2 1/2??

No, There is a two bolt flange where the tailpipe bolts to the exhaust tubing right after the muffler, the tubing size increases to 2 3/4".

i was thinking of putting a magnaflow X pipe in front of the stock muffer, cutting the muffler off and putting a couple muffers with another tailpipe, this sounds like what you did but with 07 piping right? ok my question is what size X pipe should i get for the inlets and outlets? the 2 1/4 or 2 1/2 or 3inch?

2 1/4" X-Pipe will work on the stock pipes.
