Thanks man, I see SIM is your favorite too haha.
Yeah I knew the kooks headers were the way to go but didn't see a bunch of people running their catbacks so I was little leery. But now, even with their cats this thing sounds awesome and picked up more power than I anticipated with no tune yet. Super happy with this setup so far.
My 2015 mustang buddy was alittle upset and amazed the header install was so simple.
