Here are the results of a dyno comparison between a D&D Fatcat with quiet baffle and Vance and Hines Big Shot Longs with quiet baffles.

The bike is an '06 Heritage Softail Classic with a stock engine, K&N air filter and a Power Commander.

You can see why the bike immediately felt so much stronger when I mounted the D&D. Sold the BSLs to a friend who enjoys noise.

The top (blue) line in both cases denotes the Fatcat.

 

Great comparison..................really shows the difference.

Oh heck! Now I am going to have to have them for sure. OldBoldPilot, thanks for the part number and info for the Heritage. You make it too easy.

 

how's the sound of the FatCats?

 

I will be ordering my Fat Cats tomorrow!

 

Hard to put into words. I have the quiet baffle. They are quiet at idle and in cruise, but really open up when you get on the throttle. For me, the ideal combination.

 

Thanks for the update.

I'm officially on exhaust #8 as of this morning, I ordered the fatcat.

 

Thats cool, I ordered mine too, Im on exhaust #5!

 

I must be real lucky: the Fatcat was #4 for me. H-D Torque, Rush slip-ons, V&H BSL, and the Fatcat. There won't be a #5

 

The Fatcat is #9 for me..............and there won't be a #10.
