Carbon fiber Remus is smoked
 
Hi all.....currently on a dual sport ride with a buddy of mine from NC through FL and back. Im on an 04 ktm 950 ADV with a 2 to 1 mod. Had my Remus carbon fiber exhaust tear at the rivets (the side that connects to the header). When riding, it separated, blew the fiberglass packing out, melted a hole in my plastics, melted some wiring, and I had no power to any lights, heated grips, trip computer, etc. After hours of trouble shooting, got the wires fixed, slapped a bunch of heat resistant exhaust tape on it, but still have a totally destroyed Remus exhaust. Anyone out there in the GA or FL area with a spare exhaust (maybe because you installed an auxiliary tank)? Any help would be much appreciated for we still have about 1000 miles to go.

I don't have any spares here, sorry.

Remus does not warranty the CARBON pipe for 2-1 use. Titanium version has been holding strong for over 70,000 miles now.

Good luck and safe travels.

I, too, blew out my carbon can on a ride.
Fixed it with a wrap of tin and some pipe straps. Is still holding after a few thousand miles of hard riding.
Wish you much luck finding a replacement.

Fellas, thanks for the replies. Ended up linking up with a cool shop in macon, ga called Rat Rodz. We pulled the remus apart and tossed the carbon canister. The owner took me to a machine shop he uses and they fabricated a new can out of 18ga stainless steel. All other components/guts were used. It's a bit heavy but I know there's no way it's gonna blow out. I guess I lucked out running into some good folks in macon. Only cost $125 too.

Cjracer, is a single Remus too restrictive for 2 to 1? I thought about removing the spark arrestor while it was apart

I have had a 2-1 w/ a Remus can for about 30K miles. Bike runs great with it.

if you need any KTM specific stuff in macon worth a call to Capital cycle, Brian in the parts dept is pretty well versed on KTM stuff. I know they used to be a big twin dealer, they had an SE on the floor for a long, long time that used to tempt me every time I went in there. :eek1

I don't feel that it's too restrictive.

If you are looking for ultimate HP, than yes, a 2-1 can be restrictive over a 2-2. Compared to a stock silencer setup, I feel an aftermarket 2-1 flows better than 2 stock silencers. For our trail use I only see maybe 1-2 HP loss at max RPM, but torque gained in the low end that is more helpful.

The carbon is less strong compared to stainless or titanium bodies for continuous pulses. I have also had several Aluminum bodied silencers of other brands fail b/c of this too.

You'll get more flow removing the quiet core, We have seen a 3-4 hp gain by removing that with proper jetting. I need the spark arrestor for our riding regulations in our area, so that stays in for us.

Unlined carbon cans don't tolerate the heat, either. That was primary in the cause of my failure. Many carbon cans now have SS liners inside to maintain some heat shield and solid rivet points for the caps.

I could watch composite resin in the center of the can slowly discolor. When the resin got too hot, it slowly vibrated out of the carbon cloth and all that was left was the carbon fabric, which folded...

Was that a Remus Roxx can?

Mine wasn't Remus, like OP, but Termignoni.

Remus RoxX are only available in Ti.

Remus Revolution is available in TI, Carbon, Stainless, and Alum.

I have a Remus Revolution Carbon 2-1 on a my 950 SE for testing. So far I have about 2,000 miles with no issues.

So, we're back from the ride. I figured I'd post some pics of the failed carbon remus and the "new" stainless steel version. Keep in mind all the silver tape on the first ferw pics was of my initial, failed attempt at band-aiding the busted pipe with high heat exhaust tape.

The stainelss pipe held up fine, its just heavy. The guys at Green Machine Machine shop in Macon used what they had lying around (18ga stainless). The pipe looks and sounds great.

Appreciate the replies in regards to the 2 to 1. What I've gatehred from all of your responses is this pipe (now a stainless steel Remus Revolution w/ spark arrestor in place) will do just fine.

(don't know if these pics will post properly...hopefully they will)
