test pipe installed

I got my primary cat-less pipe installed yesterday, the rest of the exhaust is oem, the secondary cats were untouch.

sound: just a little louder, only noticeable with windows down. tone is brighter at high rpm. I was really hoping it would be a louder.

power: the car feels more responsive, but I am not sure the car is pulling any harder.

smell: Couldn't smell anything.

I will install the Evolve tune in the next few days, when the ecu gather enough data. hopefully it will unleash some power.
