thinkin of putting a speewerx single pipe on a 600 cfr, is it worth the money? or should i spend it on somethin else? i have lots of other upgrades, air box, timing key, speedwerx can, speedwerx clutching,
With the aribox, key and can I would ask Jeremy at Speedwerx what he thinks. Depending on how they have designed their pipe, you might be going quite lean in the midrange.
