i was youtubing the combination, theres a few videos i found but this one sounded better than the others im assuming just better audio quality.

my question though since im a noob with cars is i have TRD exhaust it sounds good and all but would the injen intake make it sound slighty louder? or ALOT louder?

i have the trd exhaust currently, and i just added a injen sri..if definently sounds a lil bit deeper, and just makes it a lil bit louder..but you will notice the difference right away. i know i did.

oh and once you hit 4k+rpm thats when it starts to pick up the louder sound, like you have somthing under the hood

I have the Injen CAI with TRD exhaust and definitely had an increase in loudness, with a little whistling too. It's a bigger pipe and there's better airflow.

same with the TRD CAI and the TRD exhaust
