Yes exactly - middle resonator is gone completely (must have evaporated while I was driving). Just a pipe with a couple of bends from the cat to the muffler at the back.

No drone at cruising speeds. HM Headers are making these for Viezu Australia under the VAR Design name. They are a major exhaust manufacturer and manufacture exhausts for HSV, Walkinshaw, Elfin as well as aftermarket systems for a lot of other cars. So they know a bit about making exhausts.

I wasn't expecting any increase in power - just sounds like it goes faster now
