I've owned my BRZts for a few months now and absolutely love it.
But let's be real... It's QUIET and missing that burbly Subaru Boxer rumble.
THIS fixed it. You'll need WD40 to get the rubber hangars on/off easily and i would recommend a ratcheting 14MM socket and a solid wrench (same 14mm). Now for getting it straight - takes some patience, but i found that i was able to manipulate and center it best from the midpipe (just my take for what its worth). took about an hour to install give or take. Cold Starts sound so good! Higher RPM pulls are punchy and loud. Definitely going to hear some drone off throttle putting around in 3rd/4th, but who cares!?! Nobody buys these cars for comfort. Just do it.
