New exhaust system does a difference on power?

[Lilbikeilike]

I have some questions for everyone who have a non restricted exhaust system.
First : Did you feal the difference of power when you replaced the exhaust system, with or without power commander or juice box or other sorts of aftermarket chip?
Second : Is it an obligation to change the electronic chip for a power commander or juice box or other, or is it works with the stock one?
Third : Is there a sensor, I think I have read about that not sure? Is it complicated to remove and place on a R6 header?

Thanks

1) Doubt it, maybe some placebo effect change...mostly nothing more than an exhaust note change.
2) Yes you have to as you changed the A/F ratio, these devices fix the A/F maps.
3)No idea on this one sorry.

The exhaust with a power commander or juice box will add about 5hp. It also drops about 10lbs from the bikes weight. That's about a 15% increase in power. You may end up damaging your engine running an aftermarket muffler without a fuel controller and don't get the hp gains either.

Thank you guys. Very interesting.

The Viper mod with DBKiller is safe to run without a PCV.

Viper + PCV will give you about 5 peak HP but the most gain is at mid range. What you used 95% of the time.

Hey Marthy, heres my question for you. I bought my bike used and it came with the viper and db killer. As of now it has no power commander. Once I get a power commander and the appropriate map. Could I remove the DBKiller for extra loudness? Thanks

Oh ya!

Use the RevB map and set the acceleration pump then enjoy!
