Ok the car was dropped this morning with the exhaust fabricator. They are going to heat and slightly rebend the Bank 2 VRSF downpipe to get more subframe clearance. They plan to run 2 1/2" ceramic high flow cats in the mid-pipes, routing the post-cat downpipe O2 sensors there (so we should not need a delete). X pipe if room, H pipe if not, then back to the mufflers. They recommended Magnaflow over Borla ... their experience was it is a better longevity muffler.

Most of the tubing will be mandrel bent so it should be a clean design. We'll look for pictures next week.

For our cars, with a limited exhaust selection, I believe this solution will be a healthy alternative. Cost is well less than an Eisenmann or Remus system behind the dowpipes, while still supporting cats and post-cat 02 sensors.
