GRIMMSPEED FOR THE WIN. I just put one of these on my outback after fighting a cobb up pipe for over a year. The grimmspeed has thicker flanges a turbo style flex section that is more smoothe on the inside and you can get it ceramic coated for 20 bucks.

The guys on nasioc have a lot of good things to say and I couldnt agree more.
