ARK GRiP Exhaust Review (08+ STI and 11+ WRX Hatchback)
I just installed this system onto my car last night. Here are some photos and video. I will have more info up soon here:
And here's a quick video:
You can see that nearly all of the exhaust flows out of the passenger side at idle. But under load, exhaust does flow out of both sides (but probably not quite equally). The exhaust uses dual Helmholtz resonators and they really do seem to work. The exhaust is very quiet at idle and low RPM's but has a good tone at WOT. I will have more info up later.
