Been getting some custom quotes on some custom exhaust work for the 6, finally got it u on a lift and had a chance to walk around the bottom of the car. The V6 basically has a 2.25 coming into the resonator and a 2.0'' back to the rear y-pipe and exhaust. My tenative plan was to do a 2.5 from the resonator to the y-pipe, and a 2.25'' y-pipe to some magnaflows. This guy seems to know his stuff, I had a chance to look at his work on other vehicles and it looks pretty quality. The quote I got was about $500 including tax and muffler tips, however, this guy doesn't do mandrel bends, but they don't look crushed either, is there something in between? How much of a diff does mandrel make? Can you get a consistent diameter with out mandrel? Going to get a few more quotes tomorrow, so any advice would be appreciated.
