    I'm about ready to order the complete system. Headers. Stainless or titanium? Anyone else have it ?
    Got pics? Akrapovic website doesn't show much detail.

    Also, how does titanium look after repeated heat cycles?

    Same questions for the stainless headers ?


    And finally, which can should I pick ?

    BMW demo truck was at local dealer this past weekend,demo'd an 1000XR with Akra on it,Ti muffler still looked fine after I'm sure several thousand miles of test flogging :D

    Yeah, the Ti muffler doesn't get exposed to the heat, technically, it's a cover insulated from the hot internal bits. Not so the actual header and I was interested in seeing what the header would look like. Both stainless and Ti. I'm not impressed with the blemishes on the stock stainless header.

    Yes I have both am not happy with the slip on..

    BMW Akra slipon 2017 noise insert is apparently NOT removable.
    Does anyone know a fix to remove the noise insert my new BMW Akra appears to not have an insert that can be removed. Its annoyingly quiet & asthmatic, I've lost the punch I had with my aging Leo Vince it replaced.

    I keep reading the title of this thread as the "Akrapovic exhaust SUPPORT group"...

    I've just ordered full system. I've gone Ti. As far as the inserts go they do come out. The screws holding them in have a small tack weld on. You can either grind/file it off or it should just break it when you undo the screw.

    I have the full system on my 2016 GSA. I bought the stainless header and had it ceramic coated black. My main reason was an attempt at heat reduction on the right thigh. It hasn't been hot enough yet to find out if it worked. It feels like it did, but I need a 90+ day to tell for sure. I like the sound. It's not much louder than stock until you really gas it. Even then, it's not overly loud in my opinion.
    A few photos....

    These systems seem to be an incredible amount of money with little to no power improvement (as per my buddy's dino test on his 2017/8 Rally) and not much weight reduction. Am I missing something here?

    Nope. It's all a matter of preference and how much one is willing to spend.
    Just like the TracTive shocks I also just installed. While they make a really nice difference in the ride, it's not a $1800 difference, in my opinion. But I'm still glad I got them. Same with the exhaust. Unless it eliminates the heat issue I was experiencing last summer, it won't be worth anywhere near the price of the kit plus ceramic coating. But if it takes care of the issue, then it will be worth every penny.

    It just galls me to carry around a 10 pound lump that does nothing for the bike's performance at all, and that describes BMW mufflers.

    My first GS lost it's exhaust and never got a replacement. I removed the muffler and bolted a downturn tip onto the cat outlet, and the bike was still quieter than my VFR800 with the full stock exhaust system. That was near optimal. The parallel plates of the cat did most of the sound reduction work on the bike anyways. My KTM 990 ADV came with dual Akras. Two open exhausts was redundant and excessive so I did a 2 to 1 conversion and a single Akra does the job.

    My new-to-me R1200GSA came with the stock depleted uranium (or feels like it is) muffler, and I'm just getting jaded in my old age. I just can't carry around a sumo wrestler of a muffler any longer. So an Akra slip on went on this week and I'm a happy rider. It just seems wrong to carry around a huge heavy lump of metal for no good reason.

    Well, you asked. That why I did it.

    Looks awesome, was thinking of doing the black ceramic myself. Glad to see your result, great job! How much for the CC?

    Eliminating the cat will probably contribute to an overall cooler running system. Another way to deal with exhaust heat is the clothing you wear. I've found real leather pants insulate and repel heat better than nylon. Mesh pants obviously don't repel heat at all.

    I think it was $250 for the ceramic coating. They did the header pipes, the heat shield, and the inlet part of the muffler. They used some sort of new special air dry material so they didn't have to heat the muffler to bake it on. They said the heat from baking would have destroyed the carbon fiber tip.

    If you're going to coat the exhaust, no reason to spend the extra for titanium. If I remember right, the stainless was only 1lb heavier. And it was a lot less $$$. I have to say the welds on all the pieces are very nicely done.

    I also read somewhere that the new Euro4 slip-on doesn't have removable baffles...which may be the issue one of the previous posters is experiencing.

    The cat is now part of the header. No way to remove just the cat. At least that's the case for the stock header on my 2016 GSA.
