i put them on my hp 500's and love em. i can't contest to power loss but i know the cops don't look my way any more. the boat still runs the same mph as without them i was getting harrsed every weekend last week for "being too loud" this year not once. if your worried about loose just go with the next size. they make them for different HP engine's.

Added the GGB 12" inserts to the Stellings dry exhaust in my Tiger, (653" 1471 supercharged Zul's) with very good results and have not had any issues. Brought noise down from two pro stockers humping to not quite quiet enough to run inland lakes.
