Cam with Pipe??

[crewstang]

I was just wondering if this would be worth money when I buy my exhaust. It will be a full exhaust, just not certain on which one. My buddy is thinking about getting one and so was I if he did, but if only it will work. My bike is an 03 660.

i have a 03 raptor with a t4 exhaust and a stage 1 cam and i didnt see much more from the cam and head pipe but the muffler gave it the most in the bottom end
