I need help finding resonators that will quiet down my 3" TTI x-pipe system with dynomax super turbos. I idle i have a drone that drives me crazy.

I have tried dynomax race bullets as resonators but they do no help (not enough). a friend of mine loves his hushpower resonators, but they seem to be not available in 3" inlet diameter.

what is out there?

car is a 72 satellite, cases should not be too big ...
