I am new to this stuff but I was wondering if there is any after market pipes that I can put on my 03 Raptor without jetting it. If not how hard is it to jet a bike? I was looking at the Yamaha perfomance pipe. Any suggestions would be cool. Thanks

 

id get hmf for the rapotr, very cheap, extremely good, sounds soo nice. u will always have to jet, its not that bad, just a pain cuz its 2 carbs, but its not that bad

 

A pipe that doesn't require rejetting isn't worth getting.
Jetting isn't that bad it may take an hour to do the first time. There are some things to look out for, do a search on "jetting" and you'll find lots of helpful info.
I like my Yoshi pipe.

 

I would go for the FMF thats where your going to find the most HORSEPOWER

 

Sorry, but no. FMF is what it is, a good midrange, mid budget pipe. If you want hp gains over the range and on top you need to look at sparks and ct. LTE has made some big claims, but they have not been backed up yet. You are paying more for the dual exhaust than peak hp.
