Here is an idea.

Put a butterfly plate in the tail pipe run so you can throttle back the exhaust and this should quiet your system substantially.

You could set it to trigger manually from the dash with a solenoid or program your EFI system to drive a stepper motor at low load and RPM and let it open progressively or 100% with WOT'.

You could put it in your existing pipe or better yet, build a 3.5" right side exit like David's and you might pick up some more ponies.

After all, from what we are hearing your shortie headers and expecially your chambered muffler are holding you back.

Product Description
The ECV was created as an alternative to the standard silencer typically fitted in the tip of performance exhaust systems to lower the sound output. The ECV (Exhaust Control Valve) is a spring loaded butterfly valve that can be installed to the main piping of an existing exhaust system. The angle of the valve can be modified on the fly from within the cockpit to provide complete control over exhaust decibel output.


Would be cool.
