1999 R1100GS exhaust options

[Bungholio]

Looking for exhaust options for my '99 gs. It currently has a low mount, cat eliminated system but I don't know what make it is. No labels/badgeing at all on it. Exhaust sounds OK but I would like a high mount system and one that is easier to keep clean. Bike has the BMW bags with the cut out on the left side for the muffler. I was thinking Leo Vince but their website does not show an exhaust for this bike.



This is the exhaust, can anyone identify it? It looks like Staintune. Does GPR make exhaust systems for this bike? Akropovic? TwoBros? Remus?

Good, bad, easy care etc. Any information appreciated.

Can't find a decent picture of it, but I had a TwoBros pipe on my '95 and it was a POS. Loud, rough welds, loud, sloppy rivets, loud and it was loud. I also didn't like the fact that it was really fucking loud.

I ended up having the TwoBros can rebuilt and packed by a retired neighbor of mine who used to work for an exhaust shop "back in the day." Turned out much better. Still a little louder than stock (mainly due to the elimination of the cat, IMO), but much, much better than the TwoBros.

Of course, that doesn't help identify the one you have, but I can certainly recommend that you scratch TwoBros off your list.

Here's a crappy pic that doesn't show much...

Thanks, that helps alot. Definitely don't want loud. The one I have is not very loud but it does have a nice tone. I was considering getting a stock exhaust, ebay has them for about $200. Maybe I should check the Flea Market for one. I mainly want to go to the high mount since I am not using large square saddle bags that are mounted close to the bike.

The main reasons I rebuilt the TwoBros can instead of going to a stock exhaust were the weight and the heat. Ditching the stock exhaust saved over 20lbs and I no longer had the cat baking the transmission. That last issue isn't quite as important since you have the M97 tranny and it's a bit more robust than my M94.

Remus.

Finding exhausts for the 11's is getting harder and harder. Leo Vince made a can or system until like a year ago. They still listed it on their site last july when I emailed them about it. But I never heard back and two weeks after I emailed them, they pulled the part from their online catalog. Go figure...

The only game in town that comes to mind is Remus. they still make a slip on can, but it ain't cheap.

I was lucky and bought an older Remus Gran Prix system off an inmate here last summer.

My '99 had a Remus on it when I bought it. It met your first criteria; good look, easy to clean, stainless outer, high mount...

At first I liked the sound. Certainly louder than stock, and very 'growly', but not objectionable to the rider. The more I rode with it, though, the more I found myself frightening the wildlife, dogs, and many small children. Starting up and leaving a campground at 4AM was absolutely a nono.

I went back to stock and haven't looked back (well, I must've looked back a little because I still have the Remus hanging in the shop and don't really want to get rid of it 'just in case').

I have no experience in exhaust but have the following questions:

Could one split the system so you have an equally sized muffler on each side of the bike? This would lend itself to similarly sized and balanced panniers;
Could one use the custom bike set up that looks like straight pipes but has baffles installed? This would lend itself to the pannier set up I mentioned above but I have no idea how loud those systems would be.

Since I like to hear the different sounds the bike makes I also do not like loud exhaust.

As in retrofitting an 1150 header to a 1100? Possible, but i haven't tried. But I'm damn sure someone on here tried it. It should work in theory since both bikes are practically the same. But I could be wrong...like i usually am.

I did try running a straight pipe-like setup on my 1100 and it is ungodly loud. What i did as an experiment was, I took the can and ran it without it, leaving only the connecting pipe between the header and can. The pipe has a 8 inch long section double walled resonator before it empties out into the muffler. WITH the muffler, it sounds like any 1100 should. WITHOUT the muffler......its harley-like. At idle it pretty much sounds like a harley even. But at 3k its unbearable and raspy. It fun to hear or at least try once....but any ride longer than 5 minutes, you'll want to put the muffler back on.

I personally cant stand the stock system that makes it quieter than a prius and I like noisy loud bikes, but that was even too much for me. My limit was when I had a 1098 with a full 70mm race pipe system installed, no db killers...I swear I lost some hearing form that thing.

$200? I have a stock 1100 exhaust I'll trade you for what you have now.
