5# axle back setup. Quieter than RB but deeper sounding. Nice weight saving. Has less restriction than before might help performance a bit we'll see. Sound from about 5 feet behind the car. Next to the car you hear the engine's mild rotating sounds and the deeper exhaust tone. Has no-drone and S/B easily track legal for sound restricted venues. 2 1/2 inch straight-thru with side branch resonator plus DIY "resonator" (absorptive). I may adjust it to be a bit louder, especially below 100 hz, without changing the mid and high frequency attenuation characteristics (those are the ones that trigger SPL black flags cuz dBA scale is used which deemphasizes the lower frequencies). It's way quieter than many setups, but I tried to keep the deep and lower restriction to ~nothing.
