2008+ WRX H/B (no-STI)
With some gloves and with alittle bit of prepping( removing a few unnecessary hangers) we dynoed the stock exhaust and swapped it in about 10 minutes. Our results were as expected,almost 10WHP. That seems to hold true on pretty much all the Subaurswe have dynoed so far. Below are the results we got on our 08 WRX!
