I would like to know if anyone here could recomend an after market exhaust for a 2003 RX300? I am considerng Borla, Magna Flow, or Sebring? and wanted to know would this help with the HP and gas? I have installed grill guards all around my suv and a high sound system adding around 250-300 pound to the car and the gas and power are now lacking. Any advice or comments would be appreciated. thank you. you can also contact me at sound_design@hotmail.com Sean
