Here is a video from some test and tuning last summer, I was testing a set of Mickey Thompson ET Drag Radials, but it'll give anyone who's curious about what a 383 with long tube headers, true dual exhaust and Flowmaster super tens sounds like something to go on. For the record, the Mickeys spun a lot with 28 psi in them, but not near as bad as street tires; I did find later on that they hook a lot better after a short burn out and 20 psi in them.

 

Sounds great!!!

 

Any pics of the underneath to see the routing and placement of mufflers?

 

This is pretty much the only pic I have of the exhaust at the moment, at least with the super 10s on it.


Here is an old pic before the drive train rebuild (engine/transmission/rear end), but I was running the same headers and 2.5" pipe, but with a set of Loud Mouth II mufflers.
