Remus Revolution Pipe

[GSmonkey]

I'm interested in getting an aftermarket pipe with removable baffles for the GS. It seems that the Remus Revolutions are the common fitment and they look the business.

Got a few questions about them that I'd like advice:

1. I've heard one of the cans with baffle in, but with the replacement downpipes that remove the cat. This sounded great without the baffle out. I'm on a budget though and only want to spend money on a new can. So what does the GS sound like with a Remus Revolution, baffle out, but with standard downpipes and cat?? I'm after a nice 'fruity' sound, nothing too offensive. Don't want it too quiet either. Not bothered about power gains.

2. I've read on the Touratech site that they do three versions, alloy, titanium and carbon. Having owned bikes with alloy and titanium cans in the past, i fancied going for the carbon. The touratech site however states that this cannot be used with the modified downpipes (no cat). I rang touratech and they had no idea. I thought it maybe something to do with temperature i.e. the carbon is only good for the lower temperatures downstream of a cat.

3. The touratech website states that this can will give the 'true boxer sound'. Will the carbon can be noisier?? I've always thought they might be as its a thinner, more brittle construction. Can anybody provide a comparison that has heard the differnt remus cans??

4. The touratech website also mentions that you need a pipe extender for use with panniers. The touratech guy implied that this went on the outlet of the silencer. This must look cr@p, any comments??

IMHO the can material doesn't make a real difference in terms of engine noise, it is the engine itself, 2 550+cc cylinders going bang bang bang will make more noise than 4 150cc pots going bang bang bang in a sports 600.

I think therefore the material is down to personal choice. I can't bring myself to buy a Carbon fibre can, its not to my taste, i bought one alloy can and it was ruined by the end of the winter, so i only buy titanium as a choice.

I have heard/ridden a 1200GS with the Remus can that had the baffle in, it does have a great growl to it, and is audible even at high speeds, so the baffle out must be quite loud (going to get mine soon, the neighbours will love me )

Sorry i can't be of more help

I've got a titanium can on mine, it sounds great, not too loud, not too quiet, if I blip the throttle in traffic it gets the attention of the driver in front which I find useful.

I use BMW paniers (expandable ones) without the remus extension pipe and it seems fine, you need the panniers with the silver heat shield, I was told the earlier paniers had a black shield which was NFG.

I am getting a slight scorching of the number plate but it is only slight.

If you fit the end can just make sure the clamp is rotated so all the crap thrown up by the back wheel dosn't mess the threads up!

Hope all goes well, Shep

Do you know if it was just the end can, or was the cat removed as well??

Do you ride with the baffle out?? Are the downpipes standard??

I have only replaced the end can with a Remus Titanium version. Excellent build quality and finish as usual.

Baffle in the sound is impooved by far compared to the standard one.

Baffle out sounds GREAT but you have more vibration on the handle bars.

I hope this would help you choose what suits you better.

Hi GSMonkey

Standard downpipes with cat, I will have to save up for the down pipes as I hear there is a performance boost with the complete system!

Baffle in (I start off at 6am every day) I will try it removed at some time, but even if I like the sound, I doubt if the locals would!

I agree the build quality is fine

Regards Shep

I have Titanium Revolution end can on mine. It sounds great, quite loud but not too loud. I certainly don`t want anymore noise with taking the baffle out. Don`t want to draw too much attention to one self.

I also use it with my BM expandable panniers and have not encounterred any problems (I do have the new silver heat shield).

Its much lighter than stock and IMO looks much better.

Just got some quotes for the pipe:

Busters: £199 alloy, £250 titanium/carbon

SPC: £320 titanium

Touratech: £309 alloy, £384 titanium

Do touratech and BMW dealers just put £100+ on the price for a laugh or something????

YES

Sorry missed this one,

It was just the end can...there is a CAT in the standard end can too

TBH, i don't know whether a full system replacement will be of benefit without adding a powercommander and the necessary gubbins to sort the emissions system.

I think that you'll find that it isn't actually a cat in the standard can. I know that one or two websites say it is but what it really is is simply a pressure operated valve that changes the characteristics of the silencer with power.

I sit corrected (and enlightened)

Well I ended up getting an alloy can off Baz. I took the baffle out and fitted it.

Its sounds a lot different to race pipes I've put on in-line fours before. Without load on the engine it is quite quiet (Rozza friendly ), but give it some beans and its quite loud, but only with the engine on load. Quite a 'flat' sound as well.

Haven't done the downpipes, just the can. Haven't noticed any difference in performance.

It also crack and pops on overrun. I've sealed the pipe with firegum, so I assume its just a characteristic of the system. Anybody else with similar experience??

I read on a US site that they had popping and farting having replaced the can, suspect it is down to a much lower back pressure in the system when the standard unit with variable back pressure valve is removed.

As the cat is in the exhaust collector after the two headers join I wonder if it would be lots cheaper to buy the Remus(or other) collector and weld it in place of the standard one? Another advantage would be that the lambda sensors would remain and compensate somewhat for the changes. I did this on a Honda and it worked fine, but maybe that www.bbpower.de guy in Germany does a modified chip? Could be worth a visit to his site and email.

Having ventilated a Porsce 911 Carrera cat car with a equal length header system and free flowing silencer(?) plus rechipped management system I think you could get as much as 12-15% more power across the range without hurting it low down provided the cam timing is not altered.

I will be interested to hear the results after stage II.

Hi GS, yes, mine also cracks and pops on overrun with the Remus Titanium end can, also does the same with the header pipes replaced with the remus header pipes, just seems to be a quirk of the system, even with std cn and pipes you can hear a little bit of popping on the overrun IMHO.

Reduced back pressure(BP)=higher local gas velocity=higher vacuum=weaker mixture=higher o2 content=popping+farting.

And IME a less than happy feeling at low revs when the BP holds the exuberance of the motor to more human levels. The tuned up Porsche is JUST the same, but at 1200kg the effect is much less apparent.

So to be bloody boring, you can choose which extreme you like. but we bought the BM version 'cause it suited. So tread ligthtly and do not try to convert others as you may spoil their experience of a great tool.

Pace.
