Then compare that to a 80mm, JASMA-certified, HKS Super Dragger... If you ever heard one, the are VERY quiet... almost OEM-sounding- With a nice growl at WOT; but not even remotely close to as obnoxious as the smaller-diameter fart-can.
My exhaust is a 3" (76mm) 5-Zigen... Very well-resonated & unassuming until I open it up. Even then, it sounds great... But I can still carry on a conversation at 90mph without having to shout.

I can vouch for the HKS Dragger being very quiet. I've had a HiPower & a Dragger both very quiet even with a Test pipe.
I just recently put the OEM exhaust back on and at idle up to about 3500rpm the OEM and HKS are about the same.

Just run a catalytic, you will be pleased. When I was running both 85mm (3.3") HKS exhausts I was using a CATCO High Flow cat.
Like Mikester said they a very quiet at highway speeds, but when you go WOT they have a nice growl. No fartcan sound.
