Has any one installed a Flomaster Muffler on ther box? Im just wondering what it would sound like or any performance gains

 

Flowmaster will give you some of the best perfomance gains of any muffler, I have never heard one of a Scion so you have to be careful. We have installed them at our shop on Hondas and they sound like crap, however on a VW they sound great So now all we need is a guinea pig !

 

I don't mind having my box being the guinea pig. If someone give me the exhaust for free then I'll get it installed.

 

flows on a box...i wonder...too bad it's got a nice smooth sound to it instead of the uneven sound that would make flows sound best.
