Rob,

Have you or anyone else considered an electronic cut-out. I know on the old SRT-4 we put an e-cutout in place of the cat. It allowed us to stay relatively quiet until we wanted to be loud...We mounted a two-way switch in the dash and worked great... I know for the N/A an e-cutout could possibly damper performance because of the loss of backpressure, but in the SRT's that loss would actually help performance due to the FI....correct me if I'm wrong, but that would be an interesting experiment to hear/see/feel an e-cutout on a SRT-6.

I do also agree that the tips may need to be larger. They just don't seem to fill up the space well enough.
