They are looking to make these out of carbon fibre so not sure they will sport the flattened ends as on the ally ones shown. If carbon rods, metal inserts/bosses would be good at each end else if not then aluminium tubes with machined end sections welded perpendicularly on to each end where they mount to each muffler and the subframe points. That or make an X-style bracket that picks up at both fore and aft points on the subframe and at the two muffler mounts.
B The cans are supported by two carbon fiber shafts that attach to the sub frame.(In this footage their are made out of aluminum). The mount points are far forward on the can to keep them discreet.
We were aware of this while designing the system. We have used high grade titanium for the whole system and have checked headers and weakpoints for cracks from the heat. We haven't had any cracking or issues with our titanuim system. Even after aggressive heat cycles.
If you mean high grade is the same as pure Titanium, that is not the best material? have sent you the grades used by Akropovic boring? fu....d? but you dont think a short leg would improve you? Important in engineering; dimension/ tolerance, materials/ heat treatment with design?
I've seen more failures on Termignoni systems over the years than with any other manufacturer, failures on 999s (back box was a favourite weak point), 1098s and Panigales. Also Lambda bung failures on Panigale systems. Don't get me started on Zard either. Point is, I would imagine after having tested 7 systems on their bikes, I am sure Redline would have experienced some sort of critical failure by now if the materials (specifically the grade of titanium they are using) were not up to the job. It's surely not in their interest as a new company, to put out a sub-standard product, as that's a sure fire way kill a start-up business stone dead. The likes of Akrapovic and Termignoni can swallow the odd failure or defect in their design financially and move on, as they have the resources to do that. I don't believe a small new to the scene manufacturer, can afford to take that sort of a risk so if there was any doubt as to the integrity of a part then it would be madness to release it to market. I think these guys know a thing or two about welding / heat stressing/cycling etc. My understanding is that they have already amassed 1.5K miles on one test system on track with no issues. Arguably a lot more stress on parts than a road bike will experience. Don't get me wrong, I am as cautious as anyone else on here, when considering an unknown player in the field, but let's at least see what they come up with as a final street ready product (or for the track day fanatic) and then judge what they have to offer. I don't doubt they may be aspects of the design that can be improved, but like any product, it's a case of developing it to a point where it's "good enough and of an acceptible quality for the price". Anything beyond that is merely refinement. Version 2, 3, 4 etc. Sounds to me as if they are keen to listen to opinions, views etc and implement changes where and if necessary. That's re-assuring if you intend to spend almost £2000 on an aftermarket part. The fact that they have been prepared to come on this thread and to answer questions head on, speaks volumes. Still not keen on the belly pan shape though (minor point)!!
To get more specific with you guys the entire system is made out of Grade 1, annealed titanium. We have put our system through aggressive testing. We do this because as racers, we have had issues with other products at the least convenient times. With our exhaust we simply want to create a worry free product that anyone can install and use, without carrying around a trailer full of spares.
Are you able to post up a video of the bike at idle and with throttle applied? Also will you be offering any DB killers or some sort of removable baffles, as some concerns were raised over the db output, since noise limits on UK tracks of late have become quite Draconian.
Some more info from the US thread 1. Shipping is done via the site when you buy within the US. It really isn’t that expensive as the entire package weighs about 13 lbs, exhaust is 10lbs…rest is cardboard and foam. 2. We use a Grade 1, Annealed Titanium. 3. Contains everything to mount and use the exhaust. However, the belly pan is NOT included. We are finalizing it. 4. We are recommending a Rapid Bike tuning module. This utilizes the narrow band and wide band sensors. Thus, the reason the RedLine System is the ONLY system designed to accommodate both bung styles. NOW, you do not have to use the Rapid Bike, you can simply upmap. a. We recommend jumping over to a high flow K&N filter as well. If you get the stuff out fast, get it in fast too. 5. Should be shipping early November. The belly pans should be the same time too. We are really excited about making the FIRST race belly pan too. 6. Regarding the decibel rating….we don’t have one. It is deeper, it is louder…but it is not louder than an R6 at WOT. Also they state: A. We have tracked the crap out of this system. It was designed for the track. Our stock systems were melting plastic and cooking oil. B. This system dissipates so much heat, you can literally put your hand on the header five minutes after riding. C. We will be making the V4 exhaust as well… Our build quality as you can see, surpasses Akrapovic and AR. We use high quality titanium that has been argon purged. Our system sounds identical to the Akrapovic SL system Our cost is lower because we are trying to make a name for ourselves, while providing a high quality system that doesn't break the bank. This is our first product which is why we have been working on so many prototypes. The company was founded by Ducati racers, and we are currently discussing distribution with multiple Ducati dealers and Sportbike track Gear Some bold claims in there but I like a company that thinks big.
We can get a couple of those videos up for you guys by tomorrow. As of right now we are not supplying DB killers for the exhaust, but since you guys have voiced some concern over it we will consider some kind DB killer. We will also try and get some decibel measurements by tomorrow afternoon.
If you are referring to post #38 whcich is an image I photoshopped, yes I agree. That's how I would prefer to it to be shaped. Below, the left picture shows the current design, which is a much deeper profile than the PS image I've produced. Unless there are clearance issues, I can't see why the profile could not be made to flow with the lines of the lower fairing by making it shallower. From this 3/4 rear view, there seems to be a massive chasm below the exhaust and the bottom of the bellypan. I've made a rather crude attempt to show an alternative option. Ignore the actual shape on my version, it's more the reduced void/space below the pipe and the addition of a lip at the rear, to stop the rear wheel depositing a ton of crap into the bellypan, that I am trying to illustrate/emphasize. I don't necessarily have an issue with the overall shape, more the depth of the bellypan. Regards the lip I've added, on older bikes such as 916/996/998s, this lip was also curved to match the curvature of the rear tyre to aid clearance. I don't see why this could not be achieved or why the current bellypan needs to be so large (unless it's been designed primarily for a track bike to comply with track regs, if this is what is dictating the profile in the first picture). You can see how much shallower the bellypan is on the 1299SL and there is a ton of pipework going on under there, so it should be possible to compact the design.
This is a total mess; bottom profile disruptive . Left hand end complex lacks simplicity and purity? UGLY?? Bottom profile, tidy, graceful, aerodynamic. left hand end parallel to tyre? no complexity; nothing to drag eye to feature you subconsciously see as not right; CLOSE TO PERFECT; ADD HIGH REAR DAM agree, the last illustration shows there is not enough room for the rear "dam" wall
As promised we have gotten some Decibel measurements for you guys. At a 45 degree angle standing 10 feet away, holding throttle at 5000 RPM. We got a reading of 107dB.
On the SL1299 no, but on the Redline system I believe it's achievable, assuming they want to produce one and with a sleeker profile. I see where they are going in trying to produce one pan to fit all needs (predominantly track day owners) BUT in it's current guise it seems massively oversized and accepting that you must have SOME clearance so as the pipework within the bellypan doesn't melt the plastic/carbon or whatever, I still feel it could be tidied up. Only included the SL image to illustrate that even with the proximity of the lower section of pipework, you can still make the bellypan look elegant and fit precisely. I hope redline can come up with something along these lines. I guess most people are now waiting for the all important dyno charts and numbers to be posted up. BTW, is 107db a non starter for UK trackdays anyone?
