The only thing I worry about is that the bike is on the bleeding edge of lean (good gas mileage) with the free flowing muffler. I like that you said screw it and fit your own system on there. It's ridiculous what the purpose built exhaust systems cost since there are so many other mufflers that can be made to fit. I just wish the ECU was a bit more user friendly to upload maps to so that I could go directly to a tuner with a dyno and have someone set up the bike for any pipe I choose.
Its not on the bleeding edge of being lean!
Not even close.
Putting a full system on, will be on the lean side but even then its not on the bleeding edge...
There are many full systems out there that do not come with an up map.
Most of all the slip ons out there do not come with an up map.
To say its on the bleeding edge would be way over exaggarated.
I lost a ton of weight with this setup and the sound is beyond words.
