Does anyone have these fitted??

If so, I was wondering if you could share some more pics of your pannier racks? In particular, I'm wanting to see the rear, and if you could kindly measure the distance from the bike's centre-line to the right of the pannier rack. After changing the exhaust on my bike to a Scorpion, it sits out way past the my Givi racks, and am looking at solutions. Thanks in advance! :)

So are you saying that there is not enough clearance from the side panniers to the silencer? i am away now from my gs, but with Akra, there were like 3 inches distance to the rack.

Hey Kris, you can see from the pics that the Scorpion sits out ridiculously far beyond the pannier rack, meaning I cannot mount any luggage that side. Not happy with the mid-pipe's design to be sitting so far out tbh! I'm trying to decide whether to get a new exhaust, new rack, or modify the exhaust mount & fabricate an elbow so that it tucks in behind the rack (which is how it should have been in the first place!).

I've asked H&B for dimensions of their rack, and just got the generic "they fit the OEM exhaust" answer. I URGENTLY need to see from behind just like my pics, and a dimension from the bike's centre-line to the right side of the right pannier rack. Thanks so much in advance for your help mate, I genuinely appreciate it! :D

Hi Stefan, so your silencer seems to be higher, that Arka. but if you mount the side box, does it touch it? the end of the pipe is not so hot and carbon so it is maybe ok? you have plastic or aluminium panniers?

I can't mount anything on the right rack...the exhaust sticks out so far, and is exactly where a bag would go (see pictures above and below). I'm wanting to get soft Kriega bags. ;)

you can try to make small connecting pipe plus an extension to where the silencer is bolted in to lower it. perhaps just an extension could be enough so you could push the silencer lower, assuming there is enough flexibility to it.

That pretty much what I was thinking of doing...I'm happy with the height, but not the angle that it sticks out. I'd make a flanged elbow piece for where the mid-pipe meets the can, which will "tuck" the exhaust behind the pannier rack, and would allow fitment of a bag. I'd love to see some pics of your setup when you get a chance, it'd be a huge help! :)

I sent the picture above. i did not need an mods with Hepco racks and Akra pipe. Akra slip on sits much lower than stock one. I am not really clear - do you intend to use hard cases or soft bags on the bike? if the hight of your silencer is not to high, so how would changing the angle help?

Hey Kris! I need rear pics of your racks (EXACT same pics as what I posted, but on your bike), and a measurement from your bikes centre-line (as if you had sliced the bike straight up the middle), to the outside of your rack (where the bags mount).

I have a big trip coming up, must commit to the right soft-luggage options, and NEED to get this headache sorted asap lol! Plus it annoys me everytime I look at the bike lol! I'm meeting up with an engineer/fabricator 8am tomorrow morning to discuss options to "tuck" the exhaust in, so will see how that goes. ATM, you're the very best person to help me, and will be eternally greatful!!! ;)

Sorry, Stefan. I am away from the country for sometime, so I cannot give you the exact measurement. i guess my racks are similar to yours, it is just that your slip on is much higher. i think that if you undo the bolt that attaches the slip-on, and press the silencer down, you can get a sense how much lower can it go. then you could just fit a 3" plate with two holes to force the silencer to sit lower. even though you say that hight is not the issue, it will change the geometry of the all thing. i remember that some members here were concerned that this particular silencer is higher than oem, and they were right.

I have the same problem with the Hepco & Becker rack for the G 310 GS ... it is impossible to mount a bag/case, and even if you could, the hot exhaust gas will cook the base of a bag/case.

In an attempt at a solution, I tried flipping the Scorpion exhaust's subframe mounting bracket around, and mounting it inboard of the subframe, I then rotated the connecting pipe about the centre of the catalytic converter sleeve section in order to try and bring the silencer inboard and away from the rack-frame, however two issues arose with this approach;
1) the connecting pipe then makes contact with the underside of the swing-arm, &
2) the hole in the mounting bracket that secures the muffler to the subframe is now too low and slightly rearward to get the mounting bolt through the hole in the mounting bracket.

The only solution evident to me at this point is to get a competent exhaust pipe-fitter to either fabricate a custom connecting pipe, or modify the supplied connecting pipe. Looking at the best location of the silencer that would ensure a bag/case is not compromised by exhaust gases, I believe the silencer needs to be placed as follows;
1) inboard of the rack-frame,
2) further rearward, &
3) lower.

To order to achieve this, it will also be necessary to fabricate a longer mounting bracket that enables the silencer to be positioned further to the rear.

I am getting the connecting pipe modified next week to get the silencer can repositioned appropriately, I'll post some photos of the work to show how the mods turn out.

It would seem that Scorpion-Exhausts/Rally-Raid did not bother with proper testing of the fitment to ensure that the kit would fit with either H&B or Givi racks - not very clever if you ask me as many riders I know have said they'd only put the above style H&B/Givi carrier frames on this moto as it allows for the use of either soft or hard-cases on a robust mount, as well as providing the traditional GS look for hard-case frame/mounts/carriers. Plus, having an exhaust silencer sitting so far outboard on an Adv/Enduro bike is rather poor design, at it is much more likely to get damaged in a fall.

What did you end up doing to your set up Stefan?

The reason the silencer sits so far to the right is not to touch the swingarm. not a good design. in that sense the Remus silencer makes more sense to me, but I am not sure if it could be fitted with side racks? with Hepco system, the Remus would be bolted up in the same place as the Hepco, so the long washers/extensions would need to be probably modified a bit. also I am not sure if there is enough space between the Remus silencer and the side rack. possibly yes, as Remus sits very deep to the left. anybody has tried that?

the reason RR silencer is higher is because their concept of off-road bike was based on using soft bags to save the weight.

Having both the OEM and Scorpion systems it's clear that the silencer cans could have been placed further back and inboard to easily avoid contact with the swing-arm and rear brake caliper through the full range of swing-arm movement. The benefits would be both a reduced likelihood of damage to the can in a fall, and allowing H&B/Givi style racks to fit bags/cases properly. The Remus HyperCone looks like it might work, but it's worth noting that a user on the forum has indicated that it heats up the rear shock unit due to the very close proximity of the connecting pipe. Additionally, The Reumu HyperCone positions the entire exhaust system higher up and thereby raises the moto's centre of gravity.

I just looked at the details of the Remus HyperCone system, and it may not work with either H&B or Givi racks. These racks both use a long spacer to attach their racks to the underside of the seat which would force the Remus' seat mount to be lower (by 20mm in the case of the H&B rack).

perhaps the silencer connecting pipe is flexible enough to be pushed down by 20mm? 20mm is not that much. these connections are no so rigid.

Raising the center of gravity should not be issue as Remus is very light, so i would not make noticeable difference. Regarding the shock getting hot, it is getting hot anyone while riding (putting some exhaust wrap next to the shock may be an option). by the way, with Stainless Steel Akra, the big bulging part in the middle section of the exhaust pipe is also very close to the rear shock. Hence, one has to remove the shock before installing the pipe.

by the way, if there is an issue with pushing down Remus by 20mm, a simple option is to shorten the plate which attaches silencer to the top. either by cutting and welding it, or bending it more.
