Does anyone know the decibel levels for the Toda exhaust at idle, steady revs and max. Maybe wanting to change the spoon n1 to something more track friendly. Did a search and found useful info on other exhausts but not toda. Also, is it just the backbox that makes the change in noise level or is it a combination of that and the b-pipe. i.e. could I just change the backbox and get less decibels? Cheers
