I'm using the FatCat with ThunderMax w/ autotune on an '07 SG with RevPerformance 107 BB. I'm very pleased.

 

...ad best of all, look at Steve's signature pic and see how cool a FatCat will make you bike look!

Steve - it looks great, BUT I just can't believe you'd have an exhaust on only one side! Did you have to add weight so it won't fall over to the right when you try to use the jiffy stand?

Awesome sig Dude!

 

Hey, cwilks
I am looking at getting a fatcat and replacing my rineharts are well. I would love to see your dyno with the rineharts vs the dyno with the fatcat. I am looking at adding power from the 2000 to 3000 range as well. I was hoping for 10 pounds so your 20 pounds have me pumped. I was wondering what type of engine work you have? Do you have the performance baffle designed for the 95" to 103" or the standard on the fatcats? I have a 95" with the 37G, heads and 9.8:1 compression pumping out 99 horse and 104 torque but need it to come on sooner. Thanks

Here's at sheet from one of the previous incarnations of my 05 RG.
Build:
95"
9.7:1 CR
"Street Heads"
37G cams
FatCat

W/ the FatCat, the torque came on pretty early.... How does this compare to yours. w/Rineharts?

I like mine, the power is great, the sound is different and it needed to be modified so the muffler wouldn't slip back.

 

I'm actually a big fan of 2-1 exhaust on baggers..............it sets them apart from the normal slip-ons or duals. This is my 4th 2-1 on this bike, so I guess I really do like them...........and no useless ghost pipes either.

I like my sig, and your's is good too...............those guys are great.

PhilM,
That is an awesome torque curve comes on early and continues on. I have included a picture of my dyno for comparison. Am I safe to say that the way our heads and other parts of the builds were done could affect the outcome of our torque curves? Did you by chance run rineharts on yours for comparison? I would like to see the exact same bike with rineharts dynoed and then switched to a fatcat 2-1 one pipe. I think that will give me the information I am looking for. Hopefully you have a comparsion like that or someone will chirp in a post me a picture of the two dynos. Thanks for info and heres my dyno, not quite as awesome as yours but still fun to ride. If you have some ideas for me to get my torque up quicker after you look at my dyno my ears are open.

Anyone here had both Supertrapp 2:1 and FatCat 2:1? Been researching past comments on 2:1s. Had come to the conclusion from that the consensus was Supertrapp outperforms FatCat but FatCat has better sound.

But now I'm hearing FatCat outperforms Supertrapp 2:1 too?

 

I believe that MAINULTRACLASSIC (Steve) had the supertrapp on his bike and just switched to the fatcat. And from what I have read the man swaps exhaust like he should his underwear, so I would consider him to be the man to ask.
