Does any one have any suggestions for a quiet drone free set up, I have 1 7/8'' Kooks long tubes with green cats also super charged. I currently retained the stock resonator and installed a 34'' Borla 3''in/3''out multi core pre runner muffler. Sound is ok more like having a giant turbo muffler and drones pretty bad around 1500-2000rpms. I've been looking at the ford racing/ Borla touring set up was just wondering how loud it would be and if there was any drone?
