From the dyno work i've done leaving the exh. pipe alone not choking the stinger up...
Anywhere from 89~95 hp on pump gas depending on compression.
Race trim w/race fuel about 105hp depending on pipe heat.
Choke the stinger up for "kill" and you can drag another 2~3 hp out of it but not reliable for more than short burst sno-x. Even drag race is pushing it depending on diameter of plug you install in pipe....can melt piston down before an egt will register a hot temp.
