Great exhaust but difficult installation
We purchased this exhaust mostly because there are no other quality cat-back systems for the 2.5i (non-turbo). Everyone knows BORLA, so the choice was easy. We did have a difficult time connecting the pipe to the stock cat connection. It seemed like the 2-bolt flange supplied with the kit was not formed the same as the stock version. However, the stock flange is welded to the pipe going to the stock resonator. We ended up cutting off the stock 2-bolt flange to get the system to fit up and seal properly at the cat. Then the rest of the install went smoothly, and no real adjustments were even required. Muffler tip sits perfectly concentric as you'd want it in the rear bumper valance. Our Subaru is a 2008, so maybe the stock cat flange connection design changed with newer models of that same generation car. We could NOT use the one supplied with the Borla kit.
