I finally got the coupe out and went onto the highway to see how it would do. All went well, nice smooth ride, no shakes or rattles / noises. Even the exhaust was real smooth! I was worried that it would drone and cause me major annoyances.

My only "concern" was the engine rpm at 65 was a touch over 2500 rpm. Do you guys consider this to high? the current combo uses an AOD with 3.90 gears. Tires I think were 38" tall...

Anyway, what do you think?
