WERKES USA EXHAUST for the KTM390 Photos, Videos, and More - Super Sleak Look

I contacted Competition Werkes with the following question...
Can you give me any information on the difference in decibels between the stock exhaust and your exhaust? Also any information on performance vs. the stock can would be appreciated.
and this is Shawn's reply.
Still waiting on the test results. For now it's all speculative. Here's what I can say.
1) I believe HP gains will be minimal as there are not huge gains to be made on such a small displacement bike. Probably 1 to 2 HP.
2) Sound... opening up a signal. basically gives a fairly ear piercing sound. It sounds much better under load than it does on the driveway. I'd put the peak dB level at around 114. But, have to say for a signal it sounds great.
3) The one fact that I do have is that its just under 10 pounds lighter than stock. Which on a small bike means a lot.
Hope this helps.

114db! That is crazy loud. I think most tracks are limited to 98db. I think State of WA says 105db to be street legal.
And I quote once more!

Guys Don't get your nickers all tied up. Your basing this off Shawn's "Guess" on db level.
Do you want Facts.?? or Guess ?
Once the rain stops....... we will do db some tests, and fly by videos.
Until then........ Relax.........

Shawn works for CW are you saying you don't think he may have a good idea based on other cans they have built?
I would like to see some reading with an actual dB meter if you have access to one.

Whoa you are lucky Laguna Seca next to my house has a 90 db limit and they run a meter next to the track on the uphill between turns 5 & 6.
Some of the most insane loud pipes ive heard on liter and big twins are around 108 which is defening. So i dont doubt CW swag. But a single isnt pumping that much def over a hundred but prob barely. Even 98 at the track is a aftermarket top brand system..not like the old D&D those loud things were just around 115.
But i for one cant wait? Im predicting rain gone by tomorrow cause its supposed to start here tomorrow lol. And that the weathcast back to you Harry Johnson

I ordered one from HR a few days ago. Was told expected release was in 14-18 days. Damn, I can't wait.
lol!
At NCM a few weeks ago, bikes were getting meatballed for hitting over 103 db, a CBR 250, not sure what pipe was over the limit...

Sorry to be picky but I'd hate to spend money and then have to ditch the pipe for sound but was he at full throttle? Seems like he let off pretty soon after he passed you(the tester). Is there a place you could do a 3rd or 4th gear pull?

I've been waiting for someone to come out with a pipe that exits in the stock location. I've had my bike since the first of April. It's still bone stock, that's gona change.
hello guys, awaiting the arrival of the little beast I'm looking around for the changes to be done. I pointed this muffler .. but I also had a question ..the muffler in the following video is the same but with the brand changed? the sound seems even deeper than werker ..
