    To improve capacity for this years trip, I am considering removing the side BMW aluminum panniers and securing a drybag in there place. However, there is not much gap between the aluminum panniers and, possibly, a mounted drybag on the left side, near the muffler.

    How much heat does the muffler add to the aluminum pannier?

    Would a drybag melt with its close proximity to the muffler?

    When packing the aluminum panniers, should the mufflers heat be a consideration?

    The left side gets pretty hot. To the point I consider what I put in there. Go for a ride, stop, hop off, open it up and put your hand in there on the side next to the muffler.

    One way to reduce the heat off the end of the muffler is to add pipe extensions. Excel Cycle Werkes makes them but I don't know if they're for the pre-05 GSs. Personally I wouldn't put a dry bag down there but YMMV.

    I have the exhaust extensions...very slick well made item that does help with getting heat out the back. To dump heat out the back and not next to luggage.

    I use Ortlieb soft bags, removed my BMW Adventure boxes...saved 20+ pounds [plus boxes were not water tight and when plastic seal was broken on lid, BMW said I had to buy a new lid, seals not for sale] and less likely to trap a lower leg and break it than under a solid box when dropping bike off road [only place I ride is off road].

    What I did was attach a thin aluminum plate that conformed to each side of the BMW luggage rack as a heat shield and abrasion reducer when using the Ortliebs..works very well and adds only ounces.

    The exhaust heat will over time breakdown the material on soft bags without a shield, even with exhaust extenders.

    Soft, waterproof and light luggage is the way to go. It may not look as cool, but it is more functional.

    Excel makes them for 1150GS's they run about 90 bucks. They move a lot of heat past the bags and turn signal.

    I prefer the Givi E41's, they set further away from the bike than oem, Jesse's, or Happy trails. Since this creates an air flow things stay a little cooler in the bags and the breeze around your legs is great. Jon

    MELTED the floor of my tent that was too close to the muffler.

    Keep the aluminum plate and keep everything UP and away from the EXHAUST blast.:clap

    You can definitely feel that items are warm inside the left case, I wouldn't say hot, but yes, I try not to store liquid in the left pannier.

    hi, i live in far north Queensland, and yes I had a problem with heat in the left hand box, I went to the closest muffler shop, 70 km s away, they made me 2 pipes 200mm long slightly widened at one end, so as to slip snugly over the outside of the existing pipes, a couple of hooks welded and by using a pair of picture hooks, and a couple of exhaust springs from a auto spares, put the pipes on and tap them on till they don't go anymore, hook up the springs, finished, I have ridden outback australia, remote tracks,and they are still as secure as ever, cost less than $20.00.

    I have Varios on my GS and whenever I buy groceries I'm definitely selective about what goes in the right case vs. the left. When traveling I use the case liners which still allow some heat in the left, but I've never felt it was warm enough inside the liner to melt anything. If I felt that were going to be an issue I'd probably find some type of thin insulation to attach to the back inside wall of the left pannier.

    BMW sells a reflective, self adhesive, woven asbestos type material to protect the left bag. I put it on a Jesse sidecase. CoolIt/ThermoTec makes the same product.
    I also had a problem on my 1150gs where the stock or any other muffler rubbed my jesse sidecase with a Staintune collector box. The only muffler that won't hit the sidecase is the Staintune. That sucks cause my Remus Muffler is a much better engineered product. Staintune sucks as they definitely do not work with the stock muffler as adverised.

    +1 these made a huge difference on my Happy Trails. The temperature drop was probably 30 degrees.
