Sorry to ask this guys but i am not sure about this and need guidance. How important is it when changing to an aftermarket exhaust to also install a power commander on an 06 600 RR? Any major problems the exhaust can cause by not having a power commander?

 

if it is just a slip on its nothing you really need to worry about although if its a full system you'll want to. Otherwise your air to fuel ratio will be off and you won't be using the pipe to its full potential.

 

Ok it's a slip on so i wont worry about a power commander at this moment. Thanks for the advice though, much appreciated.
