one of my friends has a curtis sparks pipe on his 450r its bad

 

Bad are you kidding me it is in the top 10 in most power and speed

 

Looks like I am a little late on this one, but DR D gets my vote too.
I actually got mine before the DirtWheels shootout.

A friend had the full GYTR system and I was spanking him pretty bad.
He sold it on E-bay, and bought the DR D. We are pretty much dead even now when we race.[img]i/expressions/face-icon-small-confused.gif[/img]

 

I think the new Yoshi pipes for 2005 are the TRC series pipes and come with a "cone" type end cap. Last years model the TRS Off-road series did not come with a quiet coar insert. I hear that a few select Yosh models come with the insert for 05.
ATV Sport May 2005 has a full review of Quiet pipes starting on page 64. I knew that my pipe didnt have one when I bought it. I wanted un-restricted flow during the Carb re-jetting and break-in period, plus I was only riding in Glamis and Dumot at the time... (I bought the insert for 21 bucks)

Yea Buddy!....

yeah i dont think you can go wrong either way... dr. d , yosh or sparks some have more than others and what you want to spend on it... and the advantage on yosh pipes is hey every street bike that gets piped gets yosh pipes that should say something about them,
