My bike (Stock 06 TC88 w/stage 1) is in the shop at the moment having a 98" Big bore kit installed along with a set of S&S 551's. My Indy told me that he thought I should replace the V&H long shots with the D&D Fatcats for the heritage with louvered baffles, if for no other reason performance so I got them coming before he puts it on the Dyno Monday or Tuesday..Anyone else run them with this type of setup and if so what are your thoughts?

 

Best pipe in the market. You'll realize about a 10 Hp and 12-15 tq just from installing the Fatcat alone with a good tune.

 

Man that is good to hear..The pipe put me a little over the budget but he said (Indy) I wouldn't regret it..

 

I've seen the results first hand on my FXDWG. Went from 99/105 to 114/117 with just the swap from V&H Big Radius to the D&D and a correction in the tune.

 

Thanks OldEnuf for the insight..really looking forward to later this week even more.

 

D&D makes a great pipe imo....

 

Here is the Fat Cat with the perforated wrapped baffle on my 117". This bike is making 123hp/126tq. My Dad's carbureted '00 Heritage is making 76hp/90tq with the exact pipe you are mentioning with a low compression 95" big bore and some little .510 cams....He also has one on his '94 Heritage Special. Needless to say, we like and believe in these pipes...

 

I have a Fat Cat an everything you've heard about them is true, but get yourself some earplugs.

 

I've only heard good things about it. What baffle size did you get?

 

I got the louvered baffle..not sure what you mean by size?
