Wow i might go with those those sound awesome!! I was wanting louder(i have flowmaster 40s on here now and man does the drone from them get old!) I want it to be louder but i also want to be able to take it out of town.. Which if its louder itll get really old really fast! I dont have tail pipes just a dump before the axle set up
How bad is the drone? Its a REALLY tough decision as i only go out of town MAYBE two or three times a year so maybe the 9000 series wont be bad since all i do is just go to the local show and shine at sonic, as well as some crusin around town

no drone/interior resonance whatsover with these spintechs and can easily carry on a conversation inside without screaming......the super pro streets would probably be 112dbs at 1100-1200rpm idle for my set up and again thru the tail pipes
