i recently purchased a 2009 special edition 250r and have contemplated about adding a aftermarket exhuast to it. I have shopped around and have considered a slip-on two bros to sound the best. I have also heard about concerns with a full exhaust and how it would significantly change the air-fuel ratio. Also wondering if changing the exhaust would void warranty (seems like it would).

 

my daeler told me that it wont void warranty unless it can be proven that the exhaust was the one and only direct couse of the problem

 

True, I have seen dealerships already have slip on exhausts on a show room bike for sale.

 

What sound are you looking for? A deeper sound or higher pitched? I have also thought about doing something with my exhaust. By slip on do you mean it just replaces the muffler as opposed to the entire exhaust line? Let me know when you make a final decision and how it worked out.

 

Yes, a slip on just replaces the exhaust instead of the entire exhaust system. I am still deciding but, i will probably go with the deeper sound.
