I upgraded to the RPi GT Exhaust system and I will not be needing this anymore..
It's a custom exhaust done out here in Socal. New pipes are given so you do not have to ruin your stock ones. Secondary cat delete and resonator delete.
Four Glossy Black Tips.
I had a 7 HP gain on the dyno.
Exhaust is off the car. Ready to go.
Asking $900 OBO.
