Yeah the HMF is loud, but it does sound great. I used to like the Curtis Sparks pipes for the Warrior, but he quit making them, HMF is the next best thing. If noise is an issue the HMF would not be a good choice, but neither would any aftermarket pipe. They are fairly quiet if you stay off the gas, which is good so you don't wake the neighbors at 4AM.

 

i want the hmf competition whenever i get tired of the megamax

 

I would recomend the HMF competition if you wanted to race a lot or for way better throttle response. But if you're just going to ride on trails then I would but the HMF sport because it would be perfect for just messing around. Personaly i have a Big Gun "RACE" exhaust that ive had for going on three years with no problems. But for what you are looking at I would say that both "exaust 1" and "exhaust 2" are very good and reliable pipes.

 

i feel the competition is better than the sport in every aspect and quieter also
