I am new to this forum and this is my first post. Does anyone here have a Remus exhaust on their 2-valve K100 (any model) or had one at one point? If you do, or did, I would like to know if you had issues.
 

I am aware that the Remus for the K100 was developed in 1986 and is therefore for the newer style footpeg brackets and exhaust rubber mount which came about in 09/85 as the silencer was changed.

Thanks,
Tom


I'm going to add this to my post as everyone wants to talk about either noise, power or bikes other than what I posted about, a 2-valve K100. Specifically in my case it is a 1985 K100RS. My issue is with respect to how it mounts. I do have the newer style footpeg brackets and exhaust rubber mount that came about as a result of BMW changing the silencer type and mounting.

It makes a LOT of noise, power drops dramatically at low and middle RPM, and no improve at hi RPM.

No more, I threw that crap away.
I use a road legal exhaust line made by a french specialist Bobopot, for a BMW dealer, Recchia. It's pretty light and preserves the low range torque, and fits the engine tuning I've made with bigger injectors.
Anyway, the best output on all the range will always be given by the genuine exhaust...

Wish I knew how that Remus in Laitch's video was so quiet.

I know that the Remus system on my 92 K100RS had an embarrassingly loud bark around town. And the low rpm torque felt sort of limp. More noise, less pull off the line. I replaced it with a factory exhaust. Quieter with better low end grunt.

A hose clamp around the header pipes prevented cracking which was the reason the previous owner installed the Remus.

What year and model did you have it on?

I have used various Remus slip-ons and full systems on a K1200RS, an R1150R, an R1150RT, two K1200R, a K1200S and now a K1300GT. In all cases I put the 'quiet core' (where equipped) back inside after removing them for a listen, as they were often too bloody barky for riding past the church choir of a Sunday morning or droning out over the endless plains. The only one I had dyno'd was one of the K1200R and, along with a Power Commander V and dual air cleaner set-up, it gained some power in the upper middle rpm and a fair spanking bit from there to the rev limit. It lost power down low and increased the tendency to dip at approx. 3,000 rpm. The PCV could not compensate sufficiently so I imagine a stock machine's black box electronic magic also not having the ability. They sure are light and pretty, however, especially in carbon-fibre. I recommend them because we should all be able to have the fun and make the mistakes (just for the pleasure) of our forebears.

Mine is like that. It has a lovely rumble at idle but it doesn't get noisy as I rev it.
