Any you guys running a single muffler exhaust?

I was hoping it was going to be quieter because it has a heimholtz resonator in the mid-pipe, but I'm considering having a straight-through muffler installed in the mid-pipe (downstream of the heimholtz) to reduce overall volume.

I had the Nameless muffled track pipe with 5" muffler before, and that is quiet compared to the HKS. Both this setup and with the HKS catback had similar weight.

I should have probably gone with the Tanabe Medallion single exit. It's supposed to be one of the quietest straight-through design single exit catback systems.

Yep, love it. I have an AT so cruising around town is at super low RPM and there is no drone like the other 3 exhaustsI tried. Very smooth rumble. Can't wait to get headers and it'll be perfect for me imo.
