want to know the best exaust for a yfz 450, for power and long distance races!

also who would win between yfz450 and 450r

 

i would go with the dr.d full pipe. i put a slip on on my raptor and it was amasing. i have herd even better things about them on a yfz. the full pipe will give you a lot more top end too.

 

i also believe that you would most likely win against a 450r. mostly the drivers though.

 

this question has been asked several times in this
forum so you wont get much of a responce,
i have a yfz and im still trying to decide what kind of
exaust to use. ive heard good things about all of these

yoshimura
pro circuit
gyt-r
sparks

and the yfz will win for shure

 

I would get the gyt-r muffler put on it

 

I use a full gyt-r on my yfz and my raptor and they run great! My 450 has not lost a race yet to

 

yoshi pipe yoshi is the best for 4 strokes in my mind

 

I was also wondering what exhast should i get for my other raptor?

Pulse Charger
or
Yoshimura?

 

You can't forget the FMF Factory4 titanium system, it's just as good if not better than any of those. This is the pipe that redeems FMF past of poor 4 stroke pipes, trust me!

*edit* Thos GYT-R pipes fall apart and don't provide the best gain in power, I wouldn't recommend them.

 

Get DR.D for them both!!
