I read a report in a cycle mag awhile back that compared about 15
aftermarket pipe with the stockers on a gs1100 Suzuki.

ONE pipe made more HP than stock, after properly jetted using a dyno,
and the gain was like 2-3%.

Several others approached the stock HP, within 5%, but the gain in
performance was attributed to a weight savings of 15-25 pounds
rather than plain HP.

To get a real gain you need much larger jets, and very good earplugs.
I would suggest saving your money unless you want to customize your
machine for looks, and take whatever performance you get, OR,
get a GSR1150!!

cheers,
