what do you have ??
or what you intend to buy ??
I am planning on the yoshimura ...
anybody have ?? negatives ? and
positives to the yosh ???

 

I bought my Yosh last november for my 98 warrior. Fit and finish are top notch. Almost a year later I still am very happy with it. Sounds great too!! I dont think you can go wrong with it.
Good luck............jm1

 

got it on tonight ....162 man jet ad 1 notch on needle ..k&n filter and xr250r module ....WOW what a differance ....will dyno tuesday

 

The new Dirtwheels says with just a slip on, The 400ex made 3 more horse than stock with the Yosh. I think thats pretty good for just a slip on. Let us know what the dyno says. Good luck!!!!!!!!!

 

How much louder is it? What was your stock HP and how much more you got with the Exuast. May I ask how much it cost you?

 

The Yosh is not as loud as any of my riding buddys wheelers. It is loduer than stock but not overly so. Power wise I put the pipe, rejetted and drilled six 1 inch holes in my air box, so with the combination of the three there is noticable power increase. I paid $200 list was $250. I really am happy with it.

 

I WAS IN TO BIG OF A HURRY TO GET STOCK HP ....IT IS QUITE A BT LOUDER THAN STOCK ....I WILL LET YOU KNOW ABOUT HP AFTER TUESDAY ..PLAN TO PUT ON DYNO AND ADJUST VALVES AND MAYBE REJETT...DEPENDING ON HOW T LOOKS ...WELL I WORK A DEALERSHIP SO I GOT A GOOD DEAL ...
SUGG.RET IS $ 477.99 NOW TAKE INTO CONSIDERATON THATS A FULL SYSTEM WITH STAINLESS HEADTUBES .....

GET THE DMC..IT IS AWESOME, AND MORE DURABLE THAN THE DUNCAN...GET IT FOR TOP END REV, A MID RANGE CAM, AND YOU WILL KICK ***
