So this is what I know that I have seen on paper...The fatcat produces about 7 lbs of more torq, 5 more hp and the torq is peaked about 400 RPM's sooner (3200rpm) than the Rinehart's True duel on stage four kits on a 2012 FL.

I have the Fatcat now and kinda thought (with my wifes thought) I would go to True duels on the new steed but changed my mind because of the power difference. I have waited for the FatCat a few weeks now for them to come in and I have no eta, when the Rinehart's are sitting on the shelf and ready for install and I bring the bike home.

Would you be fussy about that much more torq and HP? Putting yourself with the same decision?

 

With that kind of difference I would just choose which one looks better - and obviously that comes down to a personal preference.

 

If you have the Fatcat and like it, I would stick with it. I have one and for me, it's just a bit loud for my tastes.

 

 

On a bagger I want duals. I hate the sound of a Fat Cat,so the answer would be easy for me. Before it is mentioned,yes I know you can get a ghost pipe. I think a ghost pipe is stupid as hell,a damn fake pipe just for looks. I understand why people run a 2 into 1 system,I just personally like a pipe under each bag.

 

Your butt won't notice the miniscule difference of power levels between TD's and 2 into 1 systems, I'm sure. I was led to believe that TD's sound great but wish I didn't go that route because of the db levels that are catastrophic. I still will never own a bagger with one muffler hanging under the saddlebags however.

 

My experience w/ Rush slip ons, the packing burns out very quickly. You may want to look at how much packing is even left in there...However, good luck trying to get the muffler out they are a bugger, at least they were for me. I think now this is a few years back I gave up trying they were not budging.

 

Sorry but to me it's a no brainer. The Fat Cat is lighter, and will put the power where you need it. More torque 500 r.p.m. sooner is a big deal on a bagger especially. Guys in the know run 2 into 1's for good reason. They also don't care about the "unbalanced look" of their exhaust. Harleys have run the exhaust on the right side forever.

 

I agree that it is a personal preferance. Mine is true dual Rinehart's with 4" slip ons. Love the deep sound and balanced look. Don't have any torque or hp numbers but did notice a significant increase in both.

 

Guys, I have a Fatcat and have a friend with Rhinehart true duals. There is a considerable difference in torque. His bike feels sluggish at low rpm compared to mine. The 2-1 really makes a difference. Also, the Fatcat sounds great. So, do my fiend's rhineharts for that matter, but I would go with the Fatcat.
