X-Force Cat Back Exhaust Subaru STI 2008-2014 / WRX 2011-2014 - Hatchback

Out of the box, it’s beautiful. Install took about 45 minutes. Fit perfectly. The sound...I’m amazed how quiet a 3” exhaust can be. It’s literally barely louder than stock. No drone, no rasp. My OEM blowoff valve is louder. Seriously a very sedate exhaust and a great value. This is the perfect compliment to our company car build project. Couldn’t be happier.

Good quality. The installation was very simple. Dont forget the grimmspeed adapter for oem down pipe. Sound is good,a little louder than oem, not invasive, no drone except at warmup idle.

I dont know if its normal, but the 2 gaskets were fold and bend.

Fitment is good until the muffler. The exhaust tips hang down about 3 inches from the bumper, which doesn’t look good.

Sound is great, very small sound increase over stock. I prefer it to any other exhaust on a subaru.

The slip join plain sucks. It leaks and leaks and leaks. I’ve tried so many different ways of getting it perfect and it still leaks a bit. Eventually carbon will seal it off but it’s very annoying, I wish theyd charge more and put a flex joint or something. I got it to stop leaking for the most part by wrapping the exhaust with tinfoil and using some copper gasket sealer.

I would recommend to a friend.
