Borla for 2012 Impreza Sport Prmium
It took about an hour to remove the OEM muffler and install Borla. Very easy to do since the bolts were not that rusty. After installation, I realise that there is more room in the muffler slot. Borla's SS muffler is much smaller than OEM one. The extra elbow room actually helped me when I replaced the OEM 16mm rear sway bar with a STI 19mm one a week later. The exhaust notes from the Borla are louder but not too loud that would wake up the neighbors. Ilike that. I will definitely recommend it.
Magnaflow Catalytic Converters - 49 State Legal
Converter did not fit right. It was about 1.5 inches shorter than the factory one and I had to bend the supports to clear the frame. The angles were also off a little which made it hard to line up. The donut gasket for the rear did not fit the converter tube and had to be ground out for fitting.
