give the dyno guy some credit. i doubt even a bad technician would do that.

 

The bike was retuned for the pipe.
Welp...after looking at the dyno chart I feel MORE than vindicated in my decision to swap out the FC for the PP. I gave up 4 peak hp and 5 peak tq but gained 15ftlb & 8hp up to 3k where the FC always felt weak. I'm happy!

 

Thats what I see when I enlarge the sheet.

I also see the Pro Pipe kicked the D&D in the 2- 3k rpm's, which is the rpms where a lot of us spend a lot of time.

Is that the newer PP chrome or the older style BP - PP??

Yeah pretty cool huh!

It's the newer one.

 

Damn, it beats it up right in the heart of my riding range! Just what I needed, something else to think about.

 

You'll notice that 15lbs. in the low end vs. That few at the peak. I actually had some guys on the Dtna forum the other day trying to justify a 2-2 over a 2-1. They were trying to say that you would never feel the power difference and the two bikes would be even in a race. This shows how different two different 2-1 pipes can be, and they are both better than a 2-2.

 

I always felt that my bike with the FatCat never really pulled in the low rpm's especially riding 2 up. Kind of a pita at stop lights in town. I think you're right about feeling the difference where the Propipe is stronger.

 

I guess I'm looking at the results a little differently. The point of doing performance mods is to see improvement when you twist the throttle to accelerate. Between 3-4.5K RPM's, the D&D is clearly the better performing pipe.

 

Good thread, thanks for posting your results.

 

Great thread. I am getting a Pro Pipe Chrome installed on my FLHR on Wednesday. I feel like my kids before Christmas!
