It's all in the thread here... 2.5" downpipe into 3" high flow cat. stock cat-back pipe but with rear muffler deleted. Plenty of flow capacity, nice subtle sound increase. Has been a durable setup for many years now.
instead of mirror swap, since they are swiveling, one could make a motorized mirror swivel, for less air draft
I fold the driver's by hand (easy with electric windows) and deleted the passenger side like Deezler. When it was folded it blocked too much of the view out that side. I put in an interior blind spot mirror and do head checks to the passenger side. Also, I like the smooth look of the mirror delete.
The power needed to push an object through a fluid increases as the cube of the velocity. Mechanical friction increases as the square, so increasing speed requires progressively more power.
