resonators removed with Eisenmann sport

No more resonators................


Overall still reviewing the sound is changing for the better. First impression marginally louder a little more rasp but initially sounded a little less sophisticated. After 200 miles now sounds 10% increase in volume with more of a race edge.

Interesting that anytime I change something with the exhaust the engine does appear to notice. On start up it was a little more flutter to the note and seemed less crisp under initial throttle. Now seems very crisp and responsive I had the same thing with the back box on fitment, I disconnected the battery then to jog the remapping.

Inside the cabin hardly noticeable and no boom at all. Shame I was hoping it would increase the sportiness a little more than it did. I would like to hear my car driving !
