Raaze07 - Conventional Wisdom says that if you are only adding mufflers that you do not need to add an aftermarket ECM tuner, but I disagree. Now, I'm not a technician so my advice is immediately suspect.
But.... I added the MO's onto my existing setup (103" Big Bore Kit, SE Intake, HD Download and stock mufflers) and my bike immediately started running too lean. It seems that in my case the stock mufflers were the "bottleneck" in the system and since the MO's flow so much more air than the stockers, this put me into a lean condition. Since adding a Power Commander to manage the air/fuel ratio the bike runs much better.
Just sayin'....

Yes, but not a lot. Maybe another inch or two?

I installed the dresser duels with the Monster Ovals... I think it looks bad ***! However, I do think they could be a little louder and I'm thinking about removing a little bit of the packing to see what it does...
Over all, Im really happy I installed them... I'd just like little more thump out of them!
