It does not have the cat, unless its a California bike.  Doc

[LarryB]

even those do not have a cat in the head pipe. HD does not make a Cal specific bike, that's why we have issues, they make all the bikes from factory to Cal specs. the difference is the mufflers

That the first I have read about that, I was told not to buy Cal. 09 take off headers as they also have the cats in the headers on all the touring models.  Thanks Doc

I can only upload one picture per post.  I chose the charts that showed the major changes.  Stock, Baffle/Cat Removal, Tune.  We also did numerous test in between.  

Jim, I appreciate all the information that you have shared with us on the site. It has been very informative. If you have the dyno chart showing the before and after results of the cat removal, please post it.  Doesn't matter if the results were obtained before or after the baffle install so long as the only change was the removal of the cat. You can add the picture to this post.

Thanks

Removing the cat obviously makes a difference in performance.  Guys haven't been removing them for years just for fun.  It is simple physics.  However, instead of me spending more of my time printing, scanning and uploading charts, I think it would be better for you to do your own runs on your own dyno.  Nothing I say or post is as powerful as actually seeing the results first hand.  Experience is a good teacher. 

FWIW, the least destructive way to perform the cat/no-cat test is to buy a 96" header from a dealer or on ebay (they don't have a cat in the header) and do two runs (one stock and one with the 96" header w/OEM mufflers).  It is a bit more work, but you can expand the test by using Fullsac baffles or SE slip-ons.  The dyno sequence would be: 1) Stock run; 2) stock header w/performance exhaust; 3) 96" header with OEM mufflers; 4) 96" header and performance exhaust.   All tests should be performed with the stock ECM basemap (no SERT tune).  Post the charts if you do these runs.  I'm sure a lot of folks would like to see the results.

You've already been more than generous with your time. I apologize for imposing further with my request.

McGills is where you can buy the core bit to drill out your CC.

Sorry but that's the loudest I've laughed in a long time. I totally enjoyed that question. Not making fun of you, but I can't stop laughing. That was priceless.
