i think it is called the ecosystem (the quiet ones) lol i have a rincon and wondered if anyone has any opinions on the pipe as far as sound and power. thanks for ur time.

 

My buddy has one on a TRX450R and loves it. anything is better than stock though. I also read a review on one for the 300ex and it got high ratings.

 

thanks for the reply! im surprised more people dont have this pipe and reply about it? im looking for a pipe that will sound good but let me ride where i want withou people complaining like they do with my utility hmf with the quiet core. also anyone interested in buying a used rincon hmf pipe in good shape??
