I got a new C50 a few months ago and belive it or not my wife says she louder pipes on it.I've been looking around and found Cobra 2" drag pipes.What do I have to do to my fuel injection.

 

There are varying opinions about this, check volusiariders.com. It appears that the consensus is that you don't have to do anything unless you also chang the air filter to a K&N. They say that the fuel injection system will adjust. Just remember to change the gaskets when you change the pipes.

 

i have never heard off fuel mixture issues from changing exhaust....

 

I have Vance & Hines pipes on mine and never had an issue.

 

There should be no problem with the fuel.

 

Not sure about after market pipes but you can Drill, De-baffle, De-Mickey, without changing anything. I de-baffled mine and it sounds great not obknoxious but deffinately more grumble and a little more volume. You might want to try this first it's cheeper than $300.00 pipes and if then if you don't like it then buy after market.

I think if you change the head pipe to a larger diameter or change the air filter you will need a processor such as the power commander or others.
