When I saw the photos of the FS slip-ons last week I called FS to see of the full system was ready for shipping. It is so I ordered up a set. Seven days later they arrived from Italy. A bit of background...I've wanted a "proper" exhaust for my 11 prior to buying one. I've never liked the OEM one and sporting V-Twins like 2 into 1 into 2's best; Duc, Aprilia, etc. So I waited and waited, and waited some more. I picked a Jardine only for dyno testing so the 4 Gas probe could be inserted deep enough to get an accurate reading; but I never liked it. FMF's full system looks nice but it's way too loud for the street. The install was straight forward, took about 5 hours, with a couple of trips to Sears for tools; 22mm socket, and a 10mm swivle head socket. Instead of rotating the engine I dropped the swingarm. Next time I rotate... The fit and finish is outstanding. Easy install with minimal manipulation. The sound is very nice! Much fuller than the Jardine and it no longer sounds like a giant lawnmower. Performance wise it makes the motor smooth as silk! I took my bike in for the 062 flash today and my mechanic rode it before and after and was amazed at the before ride. The after didn't net that much difference. I've got dyno and DB plots from FS but they've asked me not to share them yet. I can tell you is makes some nice gains over the entire powerband. I was hoping to dyno the bike today by life ate several hours out of my schedule and I'll try in a month or so. Oh, this is the first one in North America, for what it's worth.

Very nice my friend. VERY NICE. When you do get it dynoed could you post runs from 1) stock 2) Jardine 3) Full Sys Free Spirits It would be interesting to see the difference between each setup. Oh and any soundclips yet? Take care! | ||
| Ridenusa4l |
IM SO JEALOUS!!!!!! if u dont mind me askin how much it run ya???? oh and SOUNDCLIPS!!!! THANX Jake | ||
| Vosnick52 |
That is beautiful  Definitely need a sound clip! | ||
| Hellgate |
Thanks guys, sound clips and better photos in a couple of weeks. I gotta go kill "Ivans" for a few days. T-Man: OEM to Jardine, net-net = Zero. You lose 1.5 hp between 4500 and 6500 with the Jardine. But you save 15 lbs. Cost? Ouch...I can hear it now; "WTF??? The OEM one was made by elves with pointy ears, that's too much, blah, blah, blah." With the exhange rate last week, a little more than the price of the FMF SS full system. (Message edited by hellgate on November 11, 2009) | ||

That is sooo sexy.  | ||
| Fresnobuell |
Hellgate--Have you heard the FMF in person in order to give a fair comparison in volume? Boy, it does look good. | ||
| Augustus74 |
They said no db clips, not no sound clips!!! | ||
| Wastegate |
How to convince the wife I need this? | ||
| D_adams |
Hah! I like the x-pipe execution. That's pretty much what I had in mind for one of my test project pipes, but in SS and as a slipon. I'll be trying to put that section lower under the bike though. Looks very good! | ||
| Xnoahx |
Hands down the best looking aftermarket exhaust in my eyes | ||
| Moosestang |
We need better pics than that! | ||
| Palmer |
Italian Quality!  In this we are the simply the best  . | ||

Pete: Am I to understand you are just running a stock ECM with the latest flash? We all will be interested in what the A/F values are during your dyno runs. BTW: GREAT looking exhaust! thanks for the picts. I can just hear Barker now....... and Ft_Bstd will be drooling, not to mention Chad, oooh ahhh. It is real clean looking and probably will perform. My TH is in country at the USPS waiting for my better half to pick it up today. Wife ran to USPS yesterday and guess what.... She is a great Lady, she will p/u today. | ||

That IS nice... | ||
| Fresnobuell |
For 2g's, it should be nice. For a third of the price on my new R, I couldn't imagine spending that amount of cash on any accessory. Wow. | ||

Been busy today, here’s a few answers to questions, new photos in a few hours, gotta look like I’m working you know… Fresno – I’ve not heard the FMF in person but I’ve been around race track long enough to know I don’t want a race loud system. I was talking with Zack about buying the Buell race system but based on what he described it is simply too loud. The FMF is/was the factory exhaust for the latter half of the season to the loudness should be about the same. Also the FMF doesn’t have much muffler volume, it’s small and loud. The FS is quieter than the Jardine by a couple of DB and it has a fuller sound. The Jardine is very brassy in comparison D-Adams – You’re right, the X-pipe is the key to the kingdom. It is SS, I plan to have it ceramic coated this winter as SS likes to stain, and I’m too lazy nor have the time to polish pipes. CC – I currently have the 062 flash, my prior flash was 141 and I liked it better. I think I’m going to use the 142 instead. I have ’09 fuel injectors and they like the ’09 flashes, not a nice with the 062. Once I find a flash I’m happy with I’ll install a Power Commander and see what we can do. The shop I tune with doesn’t use AFV, they use a 4 Gas EGA and tune for complete combustion instead. So I have no idea, nor care what the AFV is. I hope I don’t sound uppity with that statement but AFV doesn’t matter it’s a dynamic ratio not a static one. The tuner and owner of the shop has bikes from all over the world shipped to him for tuning and is hired from time to time to travel to Europe to tune. He’s good. Here’s more on AFV vs 4 Gas EGA: http://www.factorypro.com/dyno/4gasEGAvso2sensor.h tml Fresno – You’re correct it is very expensive but it is a good value. I didn’t weigh it but it drops about 15 lbs from stock, looks great and the motor is sooooo smooth now. I’ve not raped it yet but if feels great and now it can be tuned with this configuration. I won’t get sound clips posted for a week or so, the Army has me on the road for the next three days, then it’s hard and heavy at work next week. Thanks very much for the complements but it all goes to Free Spirits for stepping up to the plate. | ||

Hey, so can you explain the theory about 2-1-2 systems being superior for twins? | ||
| D_adams |
Scavenging. Essentially, thats it. There's several schools of thought on exhaust and there's a lot of theory behind it all. Look at some late model mustangs and camaros or corvettes. Popular aftermarket exhaust options are either an H-pipe or an X-pipe. Low end torque is the main benefit, but still maintain good HP results. Same thing with a 2-1 system, just different outlet preferences. Using an X-pipe is a bit more expensive, but if you really want a 2 inlet and 2 outlet system, it's the way to go. Oddly enough, the stock pipe uses some of this design, albeit in a longer fashion. The middle of the crossover is nearly 3 feet long and then goes back out to 2 outlets. Just for reference, a 2-1 merge collector (1.75" OD, 2.25" at the outlet) will run about $140 for a 304 SS welded setup. Double that amount and add another $30 to weld them together. That's $310 just for the x-pipe, nothing else. You'd still need all the rest of the tubing to build the exhaust. I think that's in 16 guage stainless. I prefer to weld my own stuff, but for an x-pipe, it takes a wee bit of time to do, so I don't know how many of those I'd want to make. | ||

Hi Hellgate nice pipe I would like to see the dam thing I will be at Harris Hill Friday,November 27, 2009 - Track Day if you can make it give me a call wforey | ||

"You’re correct it is very expensive but it is a good value. I didn’t weigh it but it drops about 15 lbs from stock," Dropping 15 lbs. would be quite an accomplishment, given that the stock muffler weighs only 18 lbs!  Better weigh up your new rig again. | ||
| Hellgate |
Rey I'm going to try. We're trying to figure out T-Day plans. | ||
| Barker |
its the best looking set-up I have ever seen. Now, I'm off to lay a golden egg. | ||
| Sknight |
The way an X pipe works is that when the exhaust pulse from one cylinder goes through the X it creates a vacuum in the cross pipe. That negative pressure helps suck the exhaust pulse from the other cylinder out for lack of a better term. Then that pulse goes through the X and helps the other cylinder out. When the exhaust pulse empties into lower pressure it draws more out of the cylinder than normal and more than normal raw air rushes in. That means more pure air to burn instead of residual exhaust gasses. More raw air means more fuel meaning more power. The O2 sensor should compensate some as will the MAP sensor. | ||

I wish I could knock off a 7-11 and get those pipes! Very nice. Aint got the funds to run the upper cusp of exhaust I guess | ||
| Fresnobuell |
given that the stock muffler weighs only 18 lbs CA muffler with cat weighed in at 22 lbs. | ||
| Redscuell |
Mine's w/out cat. A 15 lb. savings over a 22 lb. muffler w/ cat would mean that the F/S system, with all its additional plumbing (see poster's pics) weighs, best case, just 7 lbs. (and vs. a 48 state muffler, just 3 lbs.) I really have my doubts about either weight, but I'd be happy to be proven wrong, because it is a gorgeous install. | ||
| Fresnobuell |
I believe the non-cat muffler is heavier than 18 pounds. If you want to compare apples to apples, then you have to add the stock header pipes to the weight of the stock muffler in order to compare the F/S full system. The FMF slip-on weighs 8 pounds and that would give you nearly a 15 pound savings from a 22 pound stocker. Looking at that F/S muffler, I bet it is in the same ballpark. A 15 pound weight savings is highly plausible over the stock setup. **edited to clarify I was referring to the FMF slip on** (Message edited by fresnobuell on November 13, 2009) | ||

Pete(Hellgate), your muffler system is one of the best I have seen and I really like it a lot, albeit a little too expensive for me. If I raced though I would have it or the full Buell race pipe no longer available. Do you think it would fit under most of the stock or aftermarket lowers as some of us have? It looks kind of bulky in certain places. Good stuff Pete, enjoy. Bob |
