not bad and congrats on the mod

it definately is loud even with the silencer still in...... but it dosn't gave a deep powerfull note tho am guess because you haven't a resonator in as yet and plus you don't have in a CAI to increse the amount of air flow going in the intake. if you had one you would definately have a deeper note and more air going in which will gave you back a lil of bottom end torque

but that is up to you lol love the videos am glad to see more videos of the corolla on you tube.
