I can't really believe I've been doing this as long as I have.   Yeah, that's #199 there. To all the people who believed in me and bought one, THANKS!!! If you want the most power available for an 1125 using a slip-on exhaust, this is it. Should I do one for the 1190RX? | ||

Looks good Dean  And congrats on the sales too! How in the heck do you weld the two "Y" halves without leaks? | ||
| D_adams |
Weld the seam first, then put the merge on and weld around it. (Message edited by d_adams on February 08, 2014) | ||

I think messing with the stock RX exhaust will just be undoing their technology and probably losing horsepower. Imho. | ||
| D_adams |
If I do it, I guess we'll find out, right? | ||
| Imblasted |
maybe but if it sounds anything like my rt4 it will be worth it. | ||

Thanks Dean for all that you do. Happy to have a RT-3 on my 1125r(#49?). I know I have sold a few exhausts for you as well! lol | ||

there are no noise limitations on race use! Your systems will likely rev a bit faster | ||

I got #55rt3 thinking about repacking wondering what I should use  | ||
| D_adams |
Silent sport packing is what I put in it, most likely it's just packed down if it's getting louder, the stuff doesn't really burn out all that much. I took the original RT-3 apart after about 12-15k miles, it's all still there. I don't remember the exact mileage, but it's been abused pretty hard. This is the can that got shipped to Al for the testing, then EBR for tuning. After I got it back, I beat the snot out of it for the last couple of years. Other than being compacted to the back end of the can a little, it was pretty much all still there. This is what I currently have on my own bike, I guess it's kinda grown on me a little. Yeah, it's ugly, but it gets the job done.   | ||

soon as I get the money you'll have #201! still have yet to hear one in person and I'm sure the youtube videos don't even do it justice | ||

Oh..they are loud. You'll love it. | ||

Ok, a couple of questions as I begin my OEM exhaust replacement project  First, why do these parts always say "For Race Use Only"? By putting that on the part does it somehow absolve the manufacturer of some liability issue or are the parts truly not street legal? Second question is about the packing. Seems all the aftermarket exhausts all require packing and at some time in the future they have to be repacked. The OEM exhaust, as far as I know, has no requirement, why? Just a different type of construct? | ||
| D_adams |
It's intended for race track use, it will never come close to meeting EPA noise or emissions requirements. You can build one like this without packing, but it would be even louder than it already is. The other difference between this one and stock is weight. Stock is roughly 21-22 lbs. The one above is about 8.5 lbs. It's also the one that makes more power than pretty much anything else out there. When it's matched with the EBR race ecm, it has a potential of 143+ hp at the wheel. Mine makes right at 140, in stock trim it made 122. No engine mods, just a pipe and tune only. | ||

captjoe i can't vouch for usa laws but here in the uk its far better to run the risk of running an exhaust with 'race use only' on it rater than a fake eu stamp, the former you may get a mild telling off from the police or at worst be told to change them, however if you run an exhaust with a fake eu stamp that is fraud and get get you in serious bother, putting race use only on the exhaust absolves the manufacturer from blame, they are not stating its for road use, that responsibilty lies with the rider. the oe 1125 exhaust is full of chambers and resonators to make it quiet... and heavy and to meet various standards around the world www.aph-performance-engineering.com | ||

Albert's right. In the UK, you can potentially be charged with Perverting The Course of Justice, if you tamper with any markings on a pipe. Race pipes usually earn you a patronising telling off, and then the Copper telling you the bike sounded nice. | ||
| D_adams |
 This tells me that developing an aftermarket pipe is NOT a bad idea, assuming you know what you're doing. Why would the race teams ditch the stock pipe if not for more power? Sure, they sound awesome and all that at 11k rpm, but it can't be all about the noise, can it? I've been asked by several guys now about building one for it and I don't even have one yet. We'll see. | ||

Weight. | ||
| Dwp138 |
there is more to it than just weight...look at the diameter of the head pipe.. | ||
| Albert666 |
the pipes are 60MM iirc made here in england i have a couple of pics | ||
| Jdugger |
The race exhaust uses quite a bit larger diameter headers than stock. | ||
| Albert666 |
Each one 60mm |
