I am trying to decide between the concentric (standard) baffle and the big bore baffle. Its the D&D Fat Cat 2n1 pipe that I will be putting on my '10 FLTRX. I initially was going to get the standard but they say the big bore is way louder and I like that!! The way I understand it is that the standard is more for stock (and that is what I have,other then the zippers max flo a/c) and the big bore is more for modified engines. I guess what I want to know is will my bike run like crap if I go with the big bore baffle??? Any input will be appreciated. THANKS!!

 

WILL BE INSTALLING D&D 2>1 BOSS FAT CATS THIS SATURDAY. CAN’T WAIT TO HERE IT. I HAD THE FAT CATS WITH STANDARD BAFFLE ON MY 08 ULTRA. STANDARD IS LOUD ENOUGH AND SOUNDS GOOD. EVEN THE QUIETEST BAFFLE IS LOUDER THAN STOCK. BUT THE MORE I THINK ABOUT IT NOW, I AM GOING TO ORDER THE BIG BORE BAFFLE AND USE IT UNTIL MY 1K SERVICE TO DECIDE THEN IF ITS TO LOUD. THEN I WILL HAVE IT TUNED TO THE BAFFLE I KEEP. IF NOT I WILL ALWAYS WONDER. http://www.danddexhaust.com/catalog/2009/09/556-31.htm

 

I have the standard baffle on my 09 street glide, and trust me... It is very, very loud. I always thought I liked loud as well. BUT, I wish I would have opted for the quiet baffle. My understanding was that the big bore baffles were for 110" and up motors. The standard and quiet is recommended for up to 103" if my memory serves me correctly. I have read that quiet baffles are better performance wise as well.

 

awesome, appreciate your input!
