I have a raptor 700 and i want to put an exhaust on it. I was thinking of getting this kit. Is anyone familiar with this kit. If not this then what?

 

this kit looks good you'll get 13+hp w/kit and save money buying everything at once

 

i think it looks bad azz but dont hear to good about it as far as the dyno numbers of 13 hp but havent had the chance to ride a 700 with the trinity exhaust on it so really dont know from my point of view just others but then again what exhaust and air filter and tfi control dont make 13 hp all together ???????
