Go here for the shots I took of the race! http://www.flickr.com/photos/paulben701/sets/72157 615913693784/ Be sure to see the close-up shots of Eslicks bike and factory exhaust. (Message edited by nickdagger on March 26, 2009) | ||

Are you saying that's an 1125r? Are you sure it wasn't an 2250r?  Outstanding!  Be nice if Joe average could source a pipe like that | ||

>>>Be nice if Joe average could source a pipe like that Why couldn't Joe Average get one? They are (or will soon be as the pipeline fills) available like any other part in the Buell race catalog. You'll need a race license to get one. If that bothers you . . .
Look at it this way . . . . if I can get a race license . . anybody should be able to get one. By the way, that race pipe, like many race parts, would be a poor choice for off-track use. | ||

You'll need a race license to get one. If that bothers you . . . Write your government officials and the Trial Lawyers Assn. Get a race license. Or bribe a friend with a race license to score one for you.  | ||

By the way, "Joe Average" CAN get a pipe like that. Go to Burns exhaust components website, fill in the forms for the exhaust design, their computer will get a fairly optimized configuration for headers, collector, muffler - and they'll box up and ship the unassembled kit. Take it to your exhaust welder for fit-up and assembly. Should be pretty close. Note - the Burns software assumes some strong knowledge of the engine configuration and performance desires on the part of the "designer." http://www.burnsstainless.com/Xdesign/Race_Engine_ Spec__Form/race_engine_spec__form.htm I think that without testing costs and re-design, you might be able to get one for less than $4K (assuming your labor and dyno time is free) Some info you'll need for inputs into their software: ******** Vehicle and type of racing Racing class or category Engine manufacturer Configuration/# cylinders Maximum rpm Useable rpm range Kind of gain you want Peak horsepower @ rpm If dyno sheet, flow data or information abstract is available, please send a copy Peak torque @ rpm Displacement Additional comments Bore Stroke Compression ratio Cylinder head manufacturer Cylinder head model # of camshafts & location Type of fuel system Valves per cylinder Manifold type Carburetor or throttle size Intake valve head diameter Intake port dimensions Exhaust valve head diameter Exhaust port dimensions Cam manufacturer & model # Lifter type (roller, flat, hyd.) Intake lift at valve Intake rocker arm ratio Int. duration @ .050” lift * degrees Intake lobe centerline Intake opens @ ºBTDC Intake closes @ ºABDC Exhaust lift at valve Exhaust rocker arm ratio Exh. duration @ .050” lift * degrees Exhaust lobe centerline Exhaust opens @ ºBBDC Exhaust closes @ ºATDC * if duration @ .050” lift is unknown, specify at what lift duration is measured Header configuration ( 4-1, tri-y, etc.) Primary length Primary OD (or step diameters) Step lengths Secondary length Secondary diameter Step lengths Collector outlet diameter Tailpipe diameter Collector type ******** THEN your development/testing starts!! (trust me, $2K is CHEAP for a tested/developed racing exhaust) | ||

Damnit! There you go again, trying to infuse the internet with logic and well thought out arguments... IF you're not careful, you'll turn this into the real world! R | ||

Danny Eslick Wins AMA Pro American Superbike Race On 1125R Huh? Superbike? | ||

The race exhaust looks a lot like the Drummer to me. Appears to be a collector header with a short, fat can. I.E. "Drummer". | ||
| Slaughter |
Nope on the Drummer. The race exhaust is a FULL system, not a slip-on. | ||
| D_adams |
o0o, found a way to custom fab just about any style of pipe I want now. http://www.pjengineering.co.uk/index.asp I'm thinking the 152 mm oval at about 300 mm in length, maybe 350 mm. Stainless end cap, billet front cap. With misc hardware, packing, tubing inside and whatnot, it looks like something could be fabbed up for $300-400 US. I know there's one out there that has pre-made oval cans with a turnout, I just can't remember the name of the company. Starts with a 'V', but I am not able to find it at the moment. | ||
| Buellsrule |
Steve, I didn't say it was just like the Drummer but that it "looks a lot like a Drummer". If the "full" system, as you call it, is simply two pipes into one with a large, short can, how is that different from the Drummer? The head pipe lengths may be different and the pipe diameter may be different and the collector length may be different but the design is the same. Two into one with a can is simply that. I would love to see a dyno of the "race system" tuned next to a Drummer tuned. I wonder just how different the numbers would be. Thanks, Frank. | ||
| Slaughter |
Sorry if I was speed-reading... I'll miss points sometimes when I sneak a peek during work hours. (shhh....) I thought the Drummer was a slip-on. My bad if it's a full system. | ||
| Buellsrule |
The Drummer is not a full system. It is a mid-pipe system. The pictures posted from the link above show a single pipe entering a short, fat can. This is supposedly the Buell race exhaust. So, for clarification. It appears that the Buell race exhaust is a two into one with a short, fat can. This is very similar in design to the Drummer. Just an observation. Frank | ||
| Clarkjw |
TY Frank, thought the same thing. Testament to Kevin's work. | ||

AND....most all of the rest of the 1125 exhaust systems on the market...! Though the race system is a very nicely done, tucked in tight, long primary, somewhat long secondary into a short collector, into a short non-baffled, straight thru muffler (according to one of Eslick's team members). Drummer...? If that is said with out a snicker...then they also look like many/most CAR mufflers! And if you want to get really silly about it...ALL.....muffled exhaust systems are the same! They ALL go from the cylinder head to a muffler out to the outside of the vehicle! No matter...bike, car, truck........! Think about that for three seconds. Mike | ||
| Sparky |
Just for the record, it's a 4 into 2 into 1 system, right? | ||
| Slaughter |
4:2:1 - yes Drummer and Torquehammer are both apparently very well sorted-out exhaust systems for the 1125R but not full exhausts. Truthfully, except for racing, it'd be foolish for an aftermarket designer to put out a full exhaust for this teeny-tiny market. | ||
| Neb25 |
Did anyone notice the different front rotor on Eslicks bike. | ||
| Ridenusa4l |
It doesnt look that different but i did notice that the header coming from the rear cylinder had 2 pipes coming down from it and wrapped rather than just one, hence the full exhaust system...maybe?? Jake | ||
| Buellsrule |
Jake, you nailed it. Looks like a 4 into 2 into 1. A true full system. Gotta have one now. If only for the track. | ||
| Ridenusa4l |
oh yes of course for the "track" as in making tracks on the highway and making jap riders cry and babies(same difference lol jkjk) Jake | ||
| Ducxl |
You'll need a race license to get one. If that bothers you . . . That's the part i don't get.I can buy ANYTHING performance related from my Ducati dealer.Without being asked for silly papers.Afterall,we're just hot-rodders,right? | ||
| Madav8tr |
You can't buy a lot of stuff performance related from your Duc dealer. Most of the really trick stuff isn't available to purchase. Hell, when I was racing I had to use my race license to get a race only Termi exhaust system for my 996S. Ditto for certain bikes like the 748R where you had to have a race license just to get on the list to buy one. | ||
| Court |
Because if you sued Ducati and took everything they had all you'd have is a tax debt to the Italian government.  Anyone hungry for Burger King? | ||
| Court |
If you want to have some fun . . . on the same day I could order the EXACT exhaust that Buell is racing . . . you order the EXACT exhaust that the Ducati folks are running and see what we each get. Can you by PRECISELY THE SAME stuff they are racing? I do not know the answer to that question. I do know that for less than $20,000 I could build PRECISELY the same bike Danny Eslick won with. That's kinda cool. | ||
| Reepicheep |
Heck, for $20k, you could probably even get Mitsu to build it for you! | ||
| Doerman |
And I could help! It'd be fun. Do it Court!  | ||
