I have the new style Scorpions with DB-killers. Pics and details in my site link in my signature, including the DB killers and sound comparisons. When I first got the bike I tried it without the DB-killers and they were too loud for me. I've since done the airbox mod, which made it a bit louder and got a decat pipe, which made it a LOT louder when combined with the airbox mod. I'm now too scared to run the bike without the DB-Killers in now even as a test as I'm afraid it will make my ears bleed and deafen small children and animals as I go past.
Have some consideration for other road users before just getting loud exhausts that p!ss everyone off. It also damages the reputation of all bikers. There's a reason my Scorpions are not road-legal without the DB-killers in!
I still have the cat in and the stock air box so its not too noisy at the lower RPM's. Just listened to your sound bite, a bit quiter and not bad... Thanks for the info, it helps....
