Engine is isn't broken in and needs custom catback work. I've only have 100 miles on this car so far. LOL, and that's been driving around w/o the catback mounted. I go see the second exhaust guy today. $1400 to mod my SZ test pipes to make my B&B fit. The previous owner of the B&B had just the mufflers custom mounted. So i need piping to connect the B&B muffler to the X-pipe. I might ponder selling my setup if the price is as high as the last one.
