if you want just loud you can have the muffler replaced with a glasspack. and if u want really loud u can have the resonator removed as well, it will make the car very loud. you can also use a universal muffler put on by an exhaust shop. this might be your best bet. cat backs for solaras are more then 300. most brands make a universal muffler then can be welded on. i would go talk to a local exhaust shop to see what brands they carry or what they can get. the glasspack will be cheaper and louder though.
