Hhhmmmmmmm, wonder how many Harleys out there getting tickets for noise??? Diesel gettin a ticket for noise is just stupid. It's a whistle loud no where close to turn outs loud...
I would do a hood stack n a heart beat. Think they are sweet lookin'. I say do it
Noise isn't an issue with twins. other than the whistle it is quieter than just about any aftermarket exhaust with muffler.
