I have decided NOT to do the install. My knuckles are thanking me with relief! A local muffler shop is going to put the Banks system on tomorrow afternoon. I was thinking I'd try to do a pre- and post-op video and pics or something, just for the heck of it. It sorta depends on weather and timing, but after opening the box this afternoon, I think I'm getting a bit more than I thought when I ordered it. The tip is a double-walled, 5" diameter affair, polished 304 stainless. The other pipes are 3" stainless (304 also). With any luck, this will last longer than the apparently junky system that came stock. (But, if 50k is standard mileage on a stock system, 43k including 4 Chicago winters is probably about right....)
