Thought a thread with this title might help someone else out down the road. I have an ND 2.0 184. The previous owner took it to BBR for the Super 220. They elected to fit the super sport exhaust on top of the revised manifold and exhaust centre section.
This was NOT wise. Yes, it’s loud but not a nice sound at all. It’s like driving a pneumatic drill under load. The only relief is in 6th on a light, partial throttle.
Swapped now for the Grand Tourer version. Much better. Don’t waste your money on a super sport exhaust if your exhaust is already modified. It will not sound good.
Hope someone finds this useful.
