I love this exaust , It is not loud . I sounds almost stock. I am running headers and stock Cats .The car sounds amazing, when you step on it, thats when you get a nice deep sound. This is perfect for Cali, where smog regulation are the strict . I love this set up. I was looking for something high performance with out the loud noise, this is perfect.
However , inside the cabin you will hear the loud noise. But this is a sports car, soooo , I like it
