Unless you're completely insane, you'll be more than happy with the loudness of a HMF, Pro Circuit T-4, Big Gun race, FMF Titanium 14", or LRD. Everyone reports that these exhausts are very loud, but not enough to piss off people 500 yards away. I personally feel TC is completely unnecessary, even on a closed course racing only application. If you are a trail rider and want something ridiculously loud, YOU are contributing to the reason outsiders HATE ATVs!! Do us all a favor and go with a reasonable exhaust.
I don't care about the noise, sounds good to me loud. I have it narrowed down..TC, CT, Thunder Alley, input would be helpful. I'm pretty sure that I'm the only one who has asked about exhaust, so don't get all bent out of shape.
