Look it up on YouTube. Lots of videos with Corolla exhaust.
TRD and Borla sound the same and they will sound exactly like you hear in the videos.
Personal experience, when you first install exhaust it will sound almost too loud. But it's really not. The car will sound almost the same under normal driving, but when you mash done the pedal, VVVRROOOOMMMM!
It will grow on you quickly and in a few weeks, it'll seem like it was meant to be!
