250-500cc Exhaust for WR 300 2010

Does anyone have an aftermarket exhaust for the WR 300? If so, who? Any reflections of what is good or bad? Is there a silencer that is E3 certified too?

There's aftermarket pipes available in Europe:

Unfortunately for me, none of the US manufacturers offer anything. And I think I killed my 09' pipe for good today

Pro-Circuit makes a pipe for the 300s.

Halls has them in stock.

Is it the 250 pipe repackaged? Do you happen to know?

I've emailed them a few times over the past 10 months about a 300 pipe, but never a response.

Thanks Bud

I'll take anything at this point. Except a $300 OEM replacement.

I have now HGS/BUD Racing WR/CR 250 pipe on my WR300 2010.

And it is OK.

Hello jjhawk

How does it work compared to stock 300WR pipe ?

Thanks Klas

I am surprised HGS doesn't have a dedicated pipe for the WR 300 yet. They are usually ahead of the curve on this stuff.

Ok! Do i need a silencer with that or can i use my existing one? Do you know?

I´m not missing anything really, but i was thinking of save my new standard pipe and maybe get some more power with a new one, but i like the character of the engine so i don´t want to change that too much. Someone reported 7 hp more with the ProCircuit pipe. Sounds like a lot!

Thanks for posting the dyno chart!

Wow! The HSQ has one smooth power and torque curve vs. the rest. The GG has 20hp/cv jump in 1000RPM's in the mid I bet that thing pull real hard. And those KTM's make some killer peak numbers. Nobody is close to the linear spread of the Husky though

I bit the bullet and ordered the new pro circuit pipe and 296 silencer yesterday. I was going to get my suspension done with that money, but I dont think my stock pipe has much life left.... 3 dent removal session, one split seam welded, one hole filled in with weld and now it wont seal properly to the flange. I think I tweaked it for good at the last event.

I should hopefully have it next week. And be sure to shop around on these high priced items. I called Halls and was quoted $400 + shipping and my local ma and pa shop got it for me for $360 flat.

Yeah, the power curve looked really good on the husky! i wonder how they had the exhaust port on the KTM, if it was standard or not. Even without adjustable exhaust port the Huskys curve was best

Ok! Please leave a report when you have tried it out! I´m also thinking of one!

I've ridden a few KTM's and to me, the Husky felt like the dragster of the bunch. Soft down low, nice mid and ridiculous top end. Not quite what that graph shows.

I'm guessing the new 2010 pipe and Euro-spec jetting are the difference

I'm hoping the PC pipe will take some from the top and add to the low/mid. There's only a handful of places to really open up a 300 around here and I dont frequent them often.
