If I compare the look of all the available pipes for the Tenere (
http://www.off-the-road.de/xt660_ten...ldaempfer.html), the connector pipe section just lines up awkwardly - or not lined up at all - with the rear end of the bike frame; hence, the whole exhaust system looks out of place. The only ones that look best, again just the looks, are the stock and the GPR, both of which are essentially hugging the line of the rear end of the bike. Just an observation and IMHO.
