HR1 Riot from hardrock motorsports. couple bolts for the clamp and mounting and youre done, same as all the rest.

 

I have a D&D on my F4i. Its loud, but not obnoxious as other people have said. I'm quiet happy with the pipe, as opposed to what everyone else thought.

 

One of the quietest pipes is the Muzzy that I have heard, a bit louder than stock. The loudest is what everyone has said, D & D. If you want the sound of performance, the Two Bros. Pipe is the way to go.

 

I have a hindle on my F4i and I love it. It has a nice deep sound and isn't raspy sounding at high revs.

 

I have never heard a Hindle. If you like it, thats all that matters.

 

im gonna have to say my personal fav it 2 bros, as most here have said....D&D is on the louder end of things, and Yoshi, and expecially Akra are on the quieter end. two is loud, but very very nice sounding.

 

Here she is, check out the cool polished wheels.

 

I think my Leo Vince sounds really good. I can usually hear it well enough but when riding w/ others, I'm the quietest one.

 

I had a D&D and loved it. It has a raspy sound to it(if you like that). I recently put onthe Hardrock Riot pipe and love that even more. I keep the shutter in the middle and it is still louder than the D&D but in a better way. Its not raspy at all. My D&D is for sale if interested.

 

+1 love my Hindle Titanium
