    Hi there
    I was wondering if you guys can help me with something here. I tried to search the forum and somehow the search engine can't do it's job. It says the search engine could not handle the terms, whatever that means.
    Anyway, I purchased a F800GS about two months ago and I just purchased and I just found a straight pipe that I am eyeing on eBay.
    I have owned many motorcycles during my 30+ years of riding but I have never messed with the exhaust systems.

    I just purchased the BMW version of Akrapovic sport exhaust and I really love the smooth power delivery and sound, especially after the buffle was removed! :D

    So, what do you think about this straight pipe? Pros and cons of doing this mod?
    Thanking you in advance for your input!

    Here is the link to the pipe on the ebay.

    Thanks again :bow

    I haven't seen that header before, I thought Remus was the only available aftermarket header.

    I know with the Remus, the larger diameter pipes interfere with many skid plates, may want to check on that if you intend to do off-road riding.

    Thanks for your reply,
    No, I just do occasional off roading, nothing serious. The seller said the pipe is the same diampeter as the original one though!
    Does anybody know if I get much power gain? any downside?

    If you're dispensing with the cat' you should at the very least have the bike run on the dyno to check the air/fuel ratios and be prepared to purchase an aftermarket controller - Power Commander or similar - to have the fuelling remapped.

    Late model BMWs run very lean as they come out of the factory. Allowing the motor to breathe better by fitting a set of headers without a cat' will only make that situation worse and could well render fitting the pipes to be counter-productive.

    +1 on the above. These motors are way too lean to start with. Add a slip on and you get the decel pops. With a straight pipe and no power commander, the motor may pop.

    Thats an Arrow header its designed to be used with the stock muffler or a slip-on. The only thing you will gain by running it without a can is a headache.

    Thanks for your imput guys. Looks like its not a good idea to add the straight pipe. I will stick with the slip-on.
    Thanks again

    Thanks Olvi
    It sound like a lot of work and expense without any significant benefit.
