as is, i use the termlab and did a 146.7 on music. with some tuning im guessing itll pick up a few db's
Not saying that sound deadner won't help, but your flex is nowhwere near "out of control" so to speak... If that is as bad as the flex gets, as is, your in good shape.
yea i know exactly what you mean i know a dude who has a subaru with 2 15" shocker sig's and the roof flexes so much and loudly that the sounds like sh1t. 150+ db though.
