Well, let's see if I can keep up with the comments.
Howard, the exhaust is what I would consider loud. The "mufflers" are really straight through units and do not do much to muffle the sound. And you are correct, the car originally had a 4 to 1 with H pipe beautiful unit built by Fran and company, but the unit was too tight to the engine block and actually prevented me from removing the valve covers. And unfortunately with Jesel rockers, checking valve lash is a way of life. I used the old tubing in making the new headers.
Rx, the box is one completely rebuilt by GBOX, and is totally stock. It is a nice unit, but one has to remember to calmly shift it; no slamming gears. Last winter the car was on the chassis dyno at Gingerman racetrack and recorded 564hp at the rear wheels.
