I dont have any pictures right now, nor do i know how soon i can get some, but I just put dual exhaust on myc car this weekend. And i have to say, for only a 2.7L v6 it sounds pretty damn nice. My brother works @ a Magic Muffler, so he got keys to the shop and we did it on Sunday(that saved me paying all the shop labor... he only charged me $100 total)
The first thing we did was cut off the back 2 mufflers and left the rest of the 2 1/4 pipe back from the cats (for now anyway) then put in a Dynomax SuperTurbo muffler (its a camaro style, 2 1/2" in and dual 2 1/2" outs) Then we took some 2 1/2" to bend around the corners and the last 30 inches or so are 3" with a 45 degree angle cut on the tips (he had some 3 1/2" chrome tips there that looked pretty sweet, but his cost was like $35 or $40 each so i passed)
I'm still debating on whether or not to take out the first muffler. I'm not sure how much louder it would make it in the interior, or if i'll end up losing low end power from not having any back pressure like some other people said happened to their car. The way its set up right now, i've gained some low end power, or atleast it seems like it.
