Does anyone have one on there bike and do they make a big difference? Do you have to clutch for it?

 

I got one, don't know about a big difference..but there is a bit more power with it, it sounds better, gets a little better gas mileage. I don't have a clutch kit...yet. I've been looking at em. I want to get the FMF EFI controller too...thats probably the next purchase for mine.

 

is it pretty load or not too bad? Did it help your top end?

 

I have a Big Gun full system, and I don't think it's to loud, it's more peppier, and I did gain some top end,
It sounds very good, and they are pretty cheap, off eBay

 

Just hearing the Big Gun on You tube, I think they sound pretty close. It's a bit louder than the stock, for sure. I actually think my 800 sounds more like a 450 with an aftermarket exhaust on it ...kinda weird. I was hoping to get the sound of a small V8 like the 850 has and the 800 outty get with a slip on, not the case. But it does sound better. imo. I think the power was all thru power band, again it's not something that will snap your head back, but you will notice some gains. I'd like to get a sound clip on here some day...I'll work on that.
