For awhile now, I have wanted to get rid of the rear Y and two mufflers in favor of a single 3" muffler. I figured this would remove some weight ~15lbs and flow better as the previous exhaust shop just butted the 3" pipe into the side of the 2.5" pipe and Y'd it out.
I was really worried it would get too loud, but it's great. It is louder at idle and everywhere else, but it's not obnoxious and I think it even sounds better. I ended up replacing the two 2.5" Dynomax Super Turbo mufflers for one 3" Borla XR-1 Sportsman Race muffler. My new GoPro is being sent in for a new one as it rarely turns on and the sound isn't the best. You can still get an idea of how it sounds though. I haven't detected any real rasp, which was another thing I was afraid of.
The exhaust guy seemed amazed that I wouldn't let him pull the car on the lift. He mentioned that he's driven $200k cars and then was surprised when I said I have too, and beat the shit out of them. Once I got it on the lift and put in the air, he was looking at everything and was wanting me to explain what I wanted done. He then asked if this thing was supposed to be fast... "Do you know what whistling noise was"?
I got a few pulls in

Next step: ID1000's and 320lph pump hardwired to the battery.
EDIT: Here is the rear Y I was never happy with.
Old vs New.
