thank you. please give me more opionions

 

I like my DMC Alien pipe good low and mid gains. Looks and sounds great

 

well i got the factory 4 slip on and its awesome love the sound and the power i heard that the GYTR wuz difficult to install and didnt give u as much power as it should but i heard the HMF wuz real good but wuz very loud and DRD supposely to dirtwheels wuz the best

 

I have a full system Yoshimura with the tri oval and I love it however I got tested and my 450 was 107 decibels!

I will be fixing that, but it performs as good as any!

 

LokiDS650 what do you think of the LRD setup. Did you buy the slip on or full system? I'm looking to rid myself of my HMF and move to something else. If you have the slip on did you have any problems with it leaking where the head pipe and mid pipe come together.

 

I have been seeing alot of the ESR pipes on the fast YFZ's and not only are they cool looking but sound great too. Other than that I would get a dang Sparks pipe.......

 

how fast can the yfz go when it has the yoshi.. or the FMF pipe?

 

They would be almost neck and neck, depending on who got the holeshot prolly.

 

MOST OF THE TOP exhausts are so close that other things are gonna play more of a difference, like rider ability, how well you are tuned in, for example jetting!

 

cool
what is the top speed thought??
