Exhaust is Finally Complete
Well, it's been a bit, but I've finally got all the kinks worked out of my exhaust.
At first, I was just adding dual Magnaflow mufflers, however, I have an LS, so there's the extra step of adding piping. So we added a stainless steel pipe coming out of the stock pipe, and over to the second muffler. However, as you may have guessed, it didn't work to well (as far as even flow goes) because the exhaust doesn't really just turn down an open hole so it mainly only came out of the right muffler.
Today I took it back and we used a Y pipe adapter from Magnaflow, attached it like stock, just behind the fuel tank, with the Y part tilted slightly towards the drivers side. Then ran the passenger side out and the drivers side behind the spare tire well. Also as part of this, all my piping from the resonator back has been replaced with premium stainless steel piping (good thing too, b/c the stock piping for the passenger side muffler has been showing it's age -- thank you ODOT and all your salt). Eventually my downpipe will be replaced w/ a downpipe w/ high flow cat from ZZP, so after that my whole exhaust system will be stainless steel.
Good news is it was a little loud and droney before thanks to only using one muffler, but now that both are up and running it's cut down significantly on low RPM drone and extra noise, but still sounds AWESOME 3k RPMs and up, just not as growly as it did unfortunately, but I can live w/o that since the drone's cut down drastically.

I should have taken a few while it was up on the lift but forgot about that. Thanks Mitch, but I won't need them now. I was just trying to get a feel for how the stock Y pipe was set up, but I found a few online that did the trick.

You post ***** you! I'll take some pictures of it tomorrow. But basically it looks just like a stock setup. I'll get an in-cab sound clip too.
