Anyone using a White Bros. slip-on? What is the best slip-on for a DS? What about the end cap mod, anyone have pics. or info. on that? I might need a couple more hp to be sure to win a race against an upcoming YFZ450 race!

 

White bros seems to work well on the ds(seen one this weekend sounded nice).. But its gonna take more than that to win against a yfz even with that big rotax 650

 

I just got my White Brothers E-series on saturday (thanks to another atv connection member) and I REALLY like this slip-on.... I have had a FMF Power Core 4, MBRP, and now this White Brothers.... I like the White brothers way better than the rest I had.... It makes great power gains (from what I felt) and it sounds really good! I was always partial to White Bros anyway but EVERYONE around by me had them on thier quads so I always wanted something different, and I will tell you I don't think ANYTHING but White Brothers is going on any 4 stroke quad or bike that I have...... JMHO, but I'm really happy with white Brothers!!!!![img]i/expressions/face-icon-small-happy.gif[/img]

 

I've got the WB R-4. Nice workmanship. I really can't tell you it made a huge difference in power as I added a bunch of other stuff at the same time. Had to repack it once so far...that's kinda standard considering its nearly two years old. There was only a small chunk of packing left...thought it sounded a tad loud!!

 

I have the WB E-Series. It works well, looks excellent and isn't too loud. One of it's best features is that in the two years I've had it, the pipe still looks just as good as when it was new. I know for a fact there are A LOT of pipes on the market that CANNOT make that claim, not even after six months. Is it the best? I dunno, it's a good one though. I might try to buy a Looney Tuned Dual Exhaust pipe if they are good - however they aren't available yet.

 

From what I can gather, a stock YFZ is not terribly faster than a stock Raptor. I don't think I'm going to have much trouble with a YFZ if that's true.

I really like the WB look. I wish there were some dyno results out there with one just bolted on. I know how to make a jetting change if necessary, but would prefer not to mess around.

 

Here are some pics of my modded endcap.....Best increase for the money specially seeing how i made it myself [img]i/expressions/face-icon-small-smile.gif[/img]

Check out the exhausts for the DS 650 on Ebay right now.

 

I had the R4 with reverse meg on mine for a long time and really liked it's performance. The only complaint would be that when it came time to repack it you had to drill out the rivets and then rivet it back again[img]i/expressions/face-icon-small-sad.gif[/img]

 

I ordered my HMF slip-on last week. Johnny Raw's works great.
