Had the resondectomy performed on my bella yesterday. Removed the resonator and replaced with 2 inch straight through, 60cm longer (than the old one) resonator. Did not go down the path of a length of pipe, hotdog, or cherry bomb for fear of noise and resonance. The exhaust specialist suggested the same treatment/removal of the small resonator just b4 the muffler as it has the same restriction as the main resonator, but that will have to wait till next time. Initial feelings are, yes, its an improvement. Acceleration feels smoother and easier and stronger, sound at idle is no different, slightly lower note at high rpm. If I had to put a number to it without a dyno, I would say 2-4% better. Going to work tomorrow so will open her up and see how she performs on a 200k round trip in the country.
Will keep you all posted

Isn't a resondectomy normally performed in hospital, with sterilised equipment!?
