I'm stock - WAAAYYY too quiet. And it looks like a freaking beer keg hangin there......

 

HAHA that's true. When I took mine off to replace it, I was like, damn! It's heavy as hell too... if only beer came out of it

 

I have a 2 brothers Titanium Bolt on with a few light scratches on it I will sell ya. ITs definately louder than stock. and has good throttle response. I wanted something louder than my Micron and the 2 bro is about the same so I put my Micron back on. Interested let me know.

 

Wow ........... a sportbike that spits beer out the tailpipe...... I'm trying to think of something more perfect.
A Victoria's Secret model that likes to fish...?

 

Bought it with a D&D. I get mad compliments. All my friends are jealous of the sound. (that own bikes) I luv it!

 

I guess I'm not special mine is not on the list...

I have a LeoVinci

 

i am running stock. i dont need the police hearing me go through the gears. i like stealth mode.

 

I have an erion exhaust system. I have to agree with another on here. I'd prefer hp gains without the noise. Being stealth allows you to go through the gears and hear the feel of the bike performing. Sometimes, this has it's advantages when you don't startle situations by sound. Back on topic. To truely see hp gains, a pipe should be accompanied by a filter and a pc. The D&D is too loud. I took some additional FMF fourstroke packing and added steelwool layer around the inner baffle, then wrapped the packing around that. By creating differen't amounts of packing in the can, you can essentially adjust the tone. The steel wool helped to ensure adequate exhaust discharge while not affecting back pressure.

All of these can easily be tuned out a little by having molded headphones in the helmet to play your favorite adrenaline music to get ya in the groove either way.

 

I've got 2 929's
on my stuntbike, i'm running a 10.5 inch M4 sounds good, but it's a little raspy around 9k if that makes any sense
on my street bike, I'm running a 7.25 inch D&D, all I can say is it sucks to be behind me.

 

We have a CF akrapovic on my wifes bike. She is wanting to seel it for something different though!!
