primary cat delete+OEM mod+Evolve tune

I thought my primary cat delete was still a little too quiet, so today I did the OEM exhaust mod. I was very surprised how loud and high pitch it became. it sounded very good but I think it is a bit too loud for a daily drive car. perhaps I should have cut out the shorter section of the perforated pipe instead of the longer one. check out my video.
