Apologies for the stunning lack of updates. The car will be dyno tuned next week and then it's on to headliner, glass, interior etc. I will be driving it down to the Vintage..1300km or so, should be a great drive. In the meantime, here is a test of loud and quiet exhaust modes.
Original setup was a small cat, big mid-pipe resonator and a rear muffler with a valve to a dump pipe. We cut out the existing resonator because it was too quiet, even with the valve actuated which bypasses the rear muffler. So right now I have a rear muffler in quiet mode and a straight pipe with cat in loud mode. We will be adding in a small resonator to guard against highway drone.
In the vid it starts in loud mode then quiet, then back to loud.
