Ive serched through many forums getting info on the various scion tC exhausts and have narrowed it down to the Megan Racing exhaust or the TRD exhaust. Both sound really good and looking to you to see which one you would choose. btw i chose these for their deep sound, that they are not too loud and they last a long time (meaning they wont rust). if anyone has any other exhaust suggestions please post a sound clip/vid with its name. Thanks
