Has anyone went back to stock exhaust with a stage one air breather and if there was any significant power changes?Im running the PCIII and will continue to run it .

 

you can not go back to stock exhaust if you continue to use the pc3. you will have to get it remaped. you will run so rich you will foul plugs all the time

 

You can go back to factory exhaust. You may have to adjust your PCIII. You didn't say what exhaust system you were currently running but if it is very free flowing, going back to the factory system might be a bit of an improvement.

 

Got an email out to Fuel motto as we speak . I have Rush 1.75s on the bike right now and even though I like the sound it justs seems a little too much after about 3 hours on the road. maybe if it were a deeper tone it might be ok or Im getting old.
