Slip-on exhausts - extra performance / nicer sound vs engine longevity?

[MIKE-SA]

I am thinking of replacing the standard exhaust with a slip on, BUT...
I am concerned (having read on a previous thread on the lean running of the 1200 GS) about engine longevity.

In my experience if you want to extend your mileage - keep your vehicle standard. I don't seem to see many high-mileage vehicles - cars or bikes with high performance gear - in fact the "better" ones (in condition) are kept standard. I would like to keep my 1200 for as long as possible (I have seen 1150's with 70 000 - 90 000 km and still going strong)

The question is:
Will a slip-on pipe cause any long-term damage to the bike?

Comments?

Thanks

BMW are marketing an Akrapovic slip on through the dealer network, so they must be be happy with the running of the engine, and warranty is unaffected.

The engine is in a low state of tune so this shouldn't be a problem as long as the pipe doesn't make the bike run too lean. Would recommend a dyno run to check and you could then fit a chip if necessary.
Having said that BMW seem to set these bikes up to run lean at certain revs as standard so you can improve performance (and engine life ? ) by fitting a Wunderlich chip in any case.

Yep, that's right, I just picked up a BMW brochure selling Agrophobic end cans, at a dealer yesterday. As you say, they must be happy about the product as they recommend them.

And, if you have BM insurance they'll be covered as they have a BM part number.
