Have you seen this dyno chart?
« on: July 31, 2019, 11:13:56 am »
  just trying to get the word out to some new members about running the DB killers / silencers in your slip on mufflers. Here's a dyno comparison done on a fellow Cogger's bike. The only difference is removing the DB killer from his delkevic muffler. Look at the times on the chart. There were 4 of us Coggers present. This is the real deal. Results? A net loss of 14 HP with the silencer installed as compared to the open slip on. I have also done dyno work comparing stock to a slip on. Typically the slip on gains about 3 hp. So that means a Delkevic with it's silencer is produces a whopping 11 HP LESS THAN STOCK. 

  If your butt dyno told you that your bike gained hp with a silenced slip on, time for a recalibration.

Not sure why, but I have posted a dozen times how to modify the baffles in Delkevic mufflers, why no one has taken my advise is beyond me.

Interesting, you put their full system on the dyno yet? I removed the baffle from mine immediately, it was obviously restrictive.
I like sheds and ninjas.

I have seem many of your posts and perhaps people is doing your mod but not reporting back? Not really nice but possible.

It would be nice to see a dyno comparo including your mod as well.

That is pretty funny right there.  I hear that one all the time... then after they get Steve's flash all they can say is:
"Dam, I wish I had gotten Steve's flash a long time ago..... The money I would have saved in gas alone would have paid for his flash."
