Has anyone gone to the trouble of installing long tube catless headers and a more flow through exhaust on their 3.0 B9? Just wondering if i could gain 10 hp and have a great sound. Their is a guy in my neighborhood with a Jeep, V8, very noticeable exhaust system and special wheels, all black. I think I could duplicate that image with the Special Tribeca, my Signature SV-104 forged black power coated chrome wheels, and headers, no cats (State of Washington does not require EPA testing for car made before 2009), and a flow through muffler. Any ideas? Sort of going down the WRX/STI rabbit hole here.

I think raptor makes headers for the Subaru 6, but I'm not sure if anyone has done it. I would think there would be issues with the o2 sensors not working properly and therefore check engine lights.
