    2009 Subaru WRX
    Posted by

    "Installing it wasn't too bad, the instructions could use better pictures, but the problem was the clamps. It took forever to get the clamps in just the right spot - even with the right torque on the bolt - to not leak exhaust at the clamp. One of them still leaks a little, so I'm going to fix it with some muffler cement. Other than that issue, the exhaust sounds orgasmic to my ears, I love it. "
