You can try the dynomax super turbo or ultra turbo. If you go to their site I believe they have sound clips of their mufflers you can listen to.
Below my signature is a youtube link of my car. I have the super turbos on it by my engine is bit more built than yours and I am running 3" exhaust, but feel free to listen to it.
Sound comes in on the video around the "2:43" time mark if you want to skip to the sound.
Jim Hand also did some muffler testing in HPP magazine title "Silent Power" his testing shows the dynomax super turbo to be at 81 decibels, Flowmaster was showing 90, and open exhaust was showing 95. This was tested on Jim Hands Wagon.
