What pipes are people running on 117 builds and up? What are your likes and dislikes with the pipe?

From what I've seen alot of guys with big motors are running true duals. The slight torque dip that the duals usually produce isn't as noticable and they let the big engines breathe better. Just some info that was passed on to me and I'am sure many more opions on the subject.

D&D Fatcat would be best for the bigger builds.......

HQ site recommends 2-1 for max torque.

I think I understand John's original question.
Both he & I are running FatCat's on our motors (117 & 120 respectively). Both motors make monster torque with lower HP ratings ~ as compared to the torque.
Personally, I have been a HUGE advocate of the FatCat (as anyone who's been here a while knows). I have had great luck with it on many builds of many sizes.
I started with a Boarzilla on my 120, but it seemed to be lazy on the bottom. So I went back to FatCat, which is great on the bottom but might be holding it back on the top.
So, I think the question is more like "has anyone figured out a best of both worlds (lowend torque & upper end power) pipe for the bigger motors that really breath much more than their closer to stock counterparts?"

For mine, (S&S 124) I run the Rinehart True Duals. Love'm too. Plenty of power & torque!

Phil--Thank you for chiming in. Your re-phrase of the question is right on the mark. Hoping to have it both ways--low end TQ and longer rpm pulling power=HP.
RK Dave--I have heardr the RH true duals are a good set up for bigger builds. Might yuou have a dyno sheet you could share with us and some build details.
Actually--I have heard that the rinehart 2-1 is a good performer on bigger builds.....anyone have experience with this pipe?

I know someone that has have been doing some testing with both the RH & D&D 2-1's on 113"+ motors. It is too early to conclude anything, but initial feeling is that the RH may have been a little better. It does have a 1.875" initial step primary, compared to the 1.750 of the FatCat.
As hard as it may be to believe, the RH is even LOUDER than the FatCat w/perf baffle!

Phil--PLease keep us posted on how that progresses with the RH 2-1. We both know what the fatcat does....so this is good info to compare with.

I'm only guessing here, but my gut tells me the "best-of-both-worlds" pipe is going to end up being some kind of a hybrid. Something along the lines of an equal length 2-1 header with a modified and tuneable muffler/baffle combo.
I'm very curious to see how Dalton's 'Zilla-trapp performs. I understand it won't be an apples to apples compare to Phil's recent run because of the different throttle bodies, but should still give some kind of directional indication of the parts. He's already said he will do it when a great tuner can be secured. So we will wait and see on that.
Again, just my opinion, but an interesting topic that we can hopefully get some information about in the near future.

I may be able to give a comparison later this summer. I will start off the new build with my Fat Cat and then swap them to the Bub 7 duals with the crossover. I'll see if I can swap them when on the dyno so as to get a good comparison.

I'm going to be testing my 124" with the Rinehart 2-1 that I have plus we'll be trying both the S&S 640G cams which I originally purchased and a set of Woods 9FG's I just bought. I'm hoping the RH 2-1 performs as well as it sounds but well see. My brother in laws 120" runs extremely well with the RH true duals but with quite a bit of baffle work (cutting and welding) to get it there. If time and money permits, I'd like to swap the RH true duals off my brother in-laws 120" but not sure how far we'll get.

Should be back together this weekend to start breaking in. I'm trying to make it the week of the 26th of May but it may end up waiting until the following week. Need to upgrade the clutch before I take it up as well so still trying to decide on that. Are you looking to make a change on your bike with regards to exhaust?

John, keep the Fatcat...thats my .02 hahah...With you build it may be robbing a few hp on top, but thats not where the fun is!!!!! you want it all down low and midrange so these things feel much faster than they are.
Another pipe i like on bigger builds is the roadrage. Joe tuned a buddy's 103 with it so maybe give him a ring. They have a unique tq curve to them as well, but tend to let hp run out the other side more while only taking a bit from the bottom...Another loud pipe too...

+1 on the Road Rage, Ive said it over and over that it outperforms everything, even the D&D. Seen it with my own eyes on a 120" Made more power throught the HP and Tq curves!

Have 2-1 on my 127, hard for me to tell, new bike to me and only a couple of hundred miles on it. The book on the Ultima's , and I suspect on most big engines, is that they are very sensitive to type of exhaust and can loose as much as 40 % power w/ wrong system. Has a lot of power and the louder 2-1 helps hide a lot of engine noise.

Thanks to all who posted.....this is all good info. My builds are always a "work in progress". Just looking into other options at the moment, but also wondering what's out there that really works. PLease keep the good input coming.

I don't know if you can really have the best of both worlds with the stock gearing of the 07-08.
I think Bassani road rage 2-1 and an "evolution" gear reduction is the answer.
Just .02

I think for most of us, the build is a continual work in progress.
I went with the Boarzilla, and immediately noticed the engine was lazy on the bottom, but screamed up top. I built this for torque, not HP, and is the same exact build as Phil's execept for the TB and now the exhaust. I am striving for that "best of both worlds" by keeping the larger diameter head pipes of the Boarzilla, and modified it with a Supertrapp disc holder runing 12 discs right now and a cone end cap. This set up immediately moved the torque down to where I wanted it by the feel of the seat of the pants. Due to weather and not a lot of riding, it is not completely tuned in yet, but do plan on putting it on the dyno in a month or so. If I can raise Phils hp by 10 -15 and only lose a bit of the torque his has shown, then that will be the best of both worlds.
I did go with the EVO 30 tooth sprocket so that will add a bit to the HP/Tq reading, but still geared taller than Phils bike in 4th.
I have heard good things about the Road Rage, but it is waaay too loud for my liking. Acutally, the Boarzilla and RH TD's are also waaay too loud. The setup I am running now is very mellow.

Gearing you ask. Well--I thought about using the evo 30 T but my first gear now is a twitchy nightmare ---and--frankly--i run fast on the highway....often double the posted limit--so i didn't want to drop the rpm's. Also--My power band is down low--so the reduced gearing only means i am running through it faster---as opposed having a wider band to run through or into.
Fatcat is a great pipe--but it has limits. And--unless you do what dalton has seeimgly done by modifying the zilla, you probably can't have it both ways.....but I'm still going to try to find the best pipe possible.
Road rage--can some one post a dyno sheet possibly with a 117 or bigger build using this pipe. Loud---well i think they are all pretty lound---my fatcat with the performance baffle is f'n loud as well...

RK Dave--I have heardr the RH true duals are a good set up for bigger builds. Might yuou have a dyno sheet you could share with us and some build details.
Sorry, no Dyno sheet for me. All I know is, the Original owner, who was 71 when I bought the bike last year, was a Power Freak! He stripped his original 98 RK, that he bought new in 98, that was already tweaked as much as possible for power, and had a New S&S 124, Baker 6-speed, Barnett Clutch & the Rinehart TD’s installed, Dyno’d and tuned! Actually, I have a funny story:
I bought the RK last year, 1500 miles after the build was complete! Good thing too, as I Saved Tons of $$. The original owner said it was 131 RWHP & ‘something’ like 140’ish TQ? I thought, yeah sure, sure.  I had the bike only 2 weeks, when I installed a new Oil Pressure gauge. While out riding with my brother-in-law, it started leaking. We pulled into a local McDonalds to check things out. While trying to work on it, a guy behind me in the drive-through yells out the window of his Hummer ‘You guys having troubles?’ So I walk over and tell him the issue and ask if he has a 10mm allen wrench? So he pulls over and gets out. He says he owns a bike shop, just down the street. Then, before I can say Anything, he says ‘Hey Man, did you just buy this bike?’ I said yes, actually I did, why? He says, ‘I know this bike, I worked on it. Wasn’t this bike some old dudes, a tall Cape Verdeian guy?’ Yep, that was him, Larry. ‘Yep, Larry, that’s the dude. He had spent ton of cash on this bike and I remember it has like 131 RWHP on the Dyno, and like 143 TQ. Dam that thing is fast’. I thought great, he must have complete build info on it, right? Nope, he just bought the shop from the owner and when upgrading the Dyno machine’s software, they lost most of the stored data! Dam, no Dyno sheet for me, unless I get it done again. But, at least I now know the builder. I have my own mechanic anyway and he’s dam good to. But still, nice to meet to builder, as he was a cool dude for helping me out. BTW, he did run to his shop to get the 10mm wrench for me. Even though the shop was closed, since it was a Sunday!

Dalton, did you try the Boarzilla with the quiet baffle? Just wondering as I've heard that the quiet baffle in the zilla is a little toned down from the fatcat with the performance baffle. I know it's all relative as the 120" my b'law has with the RH true duals barks but is not obnoxious at all in my opinion but the RB Racing LSR 2-1 I tried was open header drag car loud. My RH 2-1 with the std baffle is louder than the RH true duals but no where near the RB's. I've heard good things about the Bassani as well which was recommended by R&R. Anyone have any experience from a performance perspective with the cycle shack 2" stepped 2-2's (tapered)? A Bobby Woods recommendation with a specific baffle he uses. I'm just not sure of the look, sound etc.

Yes, the pipe is the Boarzilla with the quiet baffle, and with the 120, and 10.5:1, it was anything but quiet. Also, too much pipe for the build if you want the most low end torque you can get. I still have the Zilla with the quiet baffle but with the Supertrapp disc holder. I will know in about a month or so what the results of the set-up are.
