Great sound, excellent quality, fantastic price, but just barely too loud

A beautiful exhaust that produces the most aggressive sound that I have ever heard from a four cylinder. The singular tip looks a little sad in the rectangular bumper cutout, but not that big of a deal. I'm no longer embarrassed to drive the car (previous exhaust had rusted off at the downpipe) but even with a catalytic converter installed I'm going to have to add an additional muffler or resonator to be comfortable DDing the car. It's very close to acceptable and I'm sure that many people would be fine with the volume, but with a cat it's just slightly too loud for me.
