I removed the catalytic converter from my Africa Twin crf1100 2021 model. Then replaced the OEM exhaust can with a slip-on Remus from my previous AT (2016 model). It wasn't 100% compatible because it doesn't have the exhaust valve so I removed the cables. I also removed the Remus baffle. The result is a definite reduction in power at low speed and low revs, which matters when you do technical off-road terrain. I also have cold start issues. Need to push the start button 4-5 times in the morning for it to start. It's certainly faster at high speed but I suspect it runs very lean. I've had no engin warning lights since I did the work. I will need to remap the ECU to compensate. I have done two fairly long distance gravel road trips after i did the work and I realise I may have made a mistake with removing the cat as well.
A little update, I found my Yosh slip on to be too loud and softened throttle response in low revs so I decided to try the optional spark arrestor from Yoshimura, it's the best $44 you can spend for this muffler, although it should be included, anyways, I now have the crisp low end throttle response that I was missing AND it's sounds damn near stock, it might be a tiny bit louder than stock but not by much. Now, if it's worth a total of $700 for a little less weight and better looks? Hmm...
Installed mine yesterday, nice pipe, looks fantastic and sounds great. Heat shield did not line up so I had to enlarge/lengthen holes, supplied screws are too short to hold it on. Oh, properly removing the cables is a job, not terrible but sort of a pain. Power is softer right off idle which is okay, mine always seemed snatchy at certain engine settings, midrange/upper midrange maybe gained a hp or 2. All in all, keep the stock pipe imo, unless you just want more noise and better looks. Almost too loud for my taste WITH the supplied battle installed.
@@manybikes I figure something like that would have happen . Thanks for the footage it's greatly appreciated ! Question : does this pipe have a removable insert ? If so was it installed when you run the bike engine ??
Yes... my apologies. The camera ran out of batteries. There are three or 4 screws and a few plastic rivets to remove. Then, looses the nuts securing the cables to the adjustment stays until the cables can be slipped out. Once the cables are removed you can button it back up.

Solid feedback! Thanks. Please circle back after the reMap, we’d love to hear your findings!
What is the function of the cables and the mechanism that the original exhaust has?
From what i have been told they are for cold start baffling. Not really a needed piece.
ma senza la valvola di scarico non si perdono prestazioni ai bassi regimi ?
Nope, works just fine!
@@manybikes you had to remap the ecu ?
You didn't show how to disconnect the cables on the other end
Yeah, battery died! Sorry. They just get disconnected and left in place as stated in the instructions.
Why wouldn't you show removing the actuator cables?
The battery died. Didn’t know it until I was editing. Sorry!

Awesome! Glad to hear you like the pipe. It does sound good!
Is it necessary to rewrite the ECU program because the exhaust valve is cancelled?
Nope. This bike has been running strong 20k miles since this installation with zero issues.
@@manybikes OK thanks bro
Did u remove the exhaust cables by themselves or the box on the inside of the bike also?
Guy asks a question, gets a heart. lol
Is this slip on compatible with a 2022 ATAS ?
Yes it is!
Any ECU changes needed ? Anything available yet for the 900 Rally Pro?
No ECU changes needed! No word on the Rally Pro, but I’ll ask.
Thats very nice!
Looks great eh?
@@manybikes looks and sounds awsome
What happen to the other side of the muffler valve cable , the end attached near the fender , do you just removed it ?
Totally removed it.
@@manybikes Thanks .
Battery on the camera ran out as I was removing the cables. Therefore... No footage to show unfortunately.
@@manybikes I figure something like that would have happen . Thanks for the footage it's greatly appreciated ! Question : does this pipe have a removable insert ? If so was it installed when you run the bike engine ??
@@alainbrouillette7740 It’s a street rated pipe and therefore it does have the insert. It is removable, but we did not remove it.
What did you do with the cable and setting on the computer? Just curious. Thanks.
We disconnected the cables and did nothing to the computer.!
@@manybikes Thank you. I thought the engine light will stay on for the catalytic converter connector.
Nice! Where’s the entrance to that spot?
Here is the intersection: San Bernardino National Forest
1305-1351 Lytle Creek Rd
Lytle Creek, CA 92358
United States
@@manybikes thanks man!
Yes Sir! If you want a tour of the area, let me know when you plan to head that way!
@@manybikes cool man will do , kind of new to riding dirt but love it
Did the exhaust change the tuning no popping more performance?
Kinda skipped over the exhaust servo cable removal.
Yes... my apologies. The camera ran out of batteries. There are three or 4 screws and a few plastic rivets to remove. Then, looses the nuts securing the cables to the adjustment stays until the cables can be slipped out. Once the cables are removed you can button it back up.
you really should do your research, the power was on its lowest setting not its highest lol
Not my bike... had never touched it prior to that second... SORRY. Will do better in the future ;)
