Some people over exaggerate the differences. The truth is the spread from one to the other was within a few HP and a few ft lbs. So those saying they are worthless is a pretty big stretch. The Heavy Breather produced the best low to mid range torque while the High Flow produced the best peak Hp numbers on a Stage III 114 kit. That is back to back dyno testing and tuning all on the same day and same tank of fuel! Most people will probable never feel that difference and on a stock bike they will probably perform the same. Testing is SAE correction and each unit was tested and completely tuned with each filter in place, 5th gear runs.

 

Thank you for that information!!

 

I'm going to be posting a brand new HD High-Flow AC Kit (part # 2940025) for sale in the classified section. Its brand new and never installed. I don't have the box anymore but the filter is still sealed in plastic. I'm new here and this is my first post so I can't start a new thread until I reach 5 posts.

I'm selling it because I have to keep the stock look and getting rid of the back plate would be too noticeable.

 

Why do you "have to" keep the stock look?

 

The bike belongs to my department.

 

It only eliminates the bottom plastic piece.

 

And the mesh. My supervisor would lose his mind if he saw that missing. They allow us to change pipes because we can argue that it is a safety aspect but that's it.

 

Ehh it's safety for the air cleaner too. It allows you to have a few extra ft lbs to get out of sticky situations

 

I like the way you think!

 

I noticed on the Ventilator install that there was no o-rings for the back plate Bolts but on yours there were. I am just curious if i missed something or if its a backplate design thing? Also gents, OCD is a disease! Crap like this keeps me up at night! LOL
