Yoshimura RS-4 slip-on for WR250 - who's got?

Recommended Posts

Does anyone have any experience with this exhaust?

 

I'd like to know realistically whether I'd see any noticeable increase in power with just the slip-on and no other airbox or engine mods.  No drilling the airbox, flapper mods and no fuel programmer.  Does anyone know what the weight of the RS-4 is compared to the stock can?

 

I can't find the link but I think I read somewhere where it said you don't need to put in a fuel programmer with the RS-4 or even a separate aftermarket header.

 

What say the group?

Holy crickets Batman!

I knew not alot of guys had this pipe but jeez.

Ok maybe I'll be the guinea pig.

I think that almost all have gone with the FMF, and a few with the GYTR. I cannot remember anyone besides you and SR56 mentioning the Yoshi.
