Here is an article in L&E Modified Mag I read in May of 2006 that this mod I was looking at works very well on this SL55 600HP streetcar. I marked the areas in yellow with red boarders. I was going to call RPM and find out the pros and cons of this mod on non S/C cars like the E55 00-02. Does anyone know the owner of this SL55 and if they like the mod? I think they use the system I found with a control box they built to control the opening %.

I have actually been looking for this for a while now. Any specific part number you looking at? I know E55 Baller on the forum has the cut outs and he says it's great...
I love the sound of my exhaust right now but when others get in my car for the first time, especially them girls, they always complain that it's too loud...So I was thinking I can get this done and have it quiet for when it gets too annoying and I want a quiet ride, and bump it up when I feel the need to be loud...
