Beautiful and Rare

This is exhaust is a work of art. The welds are so high quality, they are pretty. The sound is deeper than stock and a touch louder. It is very refined and mature. It opens up and demands attention when you get to 5K and higher.

I have yet to meet another 15+ WRX that has the GReddy catback. Several people have already complimented that this is the first and only that they have seen on the car.

Take the leap of faith... buy this exhaust.
