<< How loud is the bill's? >>



At idle it'e pretty mild but at full throttle it roars. It's got a real deep throaty roar. [img]i/expressions/face-icon-small-cool.gif[/img]

 

So the GYT-R Carbon slip on is pretty good? Does anyone know how loud it is compared to maybe a Yoshimura or even a stock muffler? I'm considering the Yoshi complete pipe and muffler, but I would like to have the GYT-R also, that's a Yamaha factory part isn't it?

 

The Factory Yamaha GYTR tip is great. I would either consider the HMF or GYTR as the best if noise is not an object. You need to get in line quick on the GYTR Carbon Fiber model -- Yamaha is stopping or has stopped production of it. Now they only produce the metal model.

The early GYTR carbon fiber tips have a thicker shell. The later units had a thinner shell but used a heavier packing to keep the heat off the carbon fiber. Because of a lack of proper maintenance by the end user (letting the packing go too long), the carbon will start to fail.

So it's pretty loud? That's a major factor in my purchase.

 

I have heard Fourlix talk good about the HMF with the quiet core insert. Try giving him a PM. I don't know about db but my FMF is pretty loud.

 

I have White Bros E series and as posted here very good gains top to bottom + tunable.

 

I like my HMF. I just got the quiet core mailed to me but haven't tried it yet. I also upgraded recently to the newly released polished can. It looks awesome! E-mail if you want a pic.

Yes, it is kinda loud though. But a deep loud, not a edgy FMF loud.
On the DS it put most of the power in low-end. That's where a DS needs it, I'm not sure how the Raptor pipe works. Xplor has a HMF on his 660, I think he likes his.

Pro Circut T-4. Louder than chit and great performance!

 

During the pipe shootout, the Yosh made the second most HP with only 100db.
