My last bolt-on this month was the exhaust I promised I would try. It's an exquisite item by Akrapovic (ktm.com ; $1,099), with a titanium shell and carbon fiber end cap. It's just a slip-on but still weighs 3.9 pounds to the stock muffler's 6.2 pounds. A little weight here or there isn't the issue, though; sound is what I was after. Unfortunately, it turns out most of the restriction in the exhaust comes from an underslung catalytic converter and baffle that bottles up most of the 1290's roar, so the Akro pipe only barks a tiny bit louder. It looks really sharp, but it's expensive for a mostly superficial upgrade.
