Subaru Australia Stage 2 Power Package STI Sedan 2011-2014 is rated 4.8 out of 5 by 47.
Rated 5 out of 5 by from awsome quality! Lets just say that I have been going back and forth between the cobb and the Q300 for about a year now. And final made my decision and couldnt be happier. The videos on line of the Q300 just sounded to "Tinny/Raspy" for my taste. The cobb is more of a throaty sound, which is great. If you want that nice deep tone/rumble, then get this exhaust! I have this paired with a invidia catted downpipe, just sounds awsome! Not loud and overbearing, great for a daily driven car. Build quality was excellent and no fitment problems at all, which makes this ideal for a one person install. Thanks Cobb

Rated 5 out of 5 by from Another quality cobb upgrade Great addition to my 09 wrx 5 door. Very noticeable increase in torque and boost just as the graphs show. This was my latest upgrade in addition to the cobb sf intake and SPT cat back exhaust. install : all in all it took me about 3 hours and I did it solo - would definitely take less with a helper. The install video is pretty on point. I would definitely replace the 'donut' gasket, my car only has 55k miles on it and the old gasket was rusted/gunked into the old dp... I chiseled it off and the thing was a mess, so I took the gf's car to the local dealer and bought a replacement. I also replaced the springbolts where the dp and mid pipe connect, mine were pretty rusted and one of the springs actually broke when I took it off.

Rated 5 out of 5 by from Awesome product Me and my buddy put this on and it took us about 5 hours of partially goofing around and such. For the 2016 STI it is nearly impossible to get to the turbo heatshield / downpipe without taking off the intercooler. I am currently running a Muffler Delete Axle Back system ontop of this, and it sounds awesome. It is deep and has a nice rumble. The major difference I noticed between Stage 1+ and Stage 2 is that boost hits and holds 17-18lbs at 4000 rpms in stage 1+, but in Stage 2 it hits around 10lbs at 3500-4000 and then starts building but is way torque-ier. Over all, awesome product and I recommend it if you are looking for a little extra kick

Rated 5 out of 5 by from IMO Best Sounding Exhaust This exhaust has to be one of, if not THE best sounding exhaust for the STI sedan that is made. The exhaust tone is deep and throaty and has no "pingy" sound at high RPM. There is no drone at 60-80 mph while in 6th gear driving on the highway. Its super sexy too. Sticks out just enough, and hangs perfect with the stock hangers.

Rated 5 out of 5 by from Everything I expected and more! Installing the Cobb emblem added 5whp. Best mod ever.

Rated 5 out of 5 by from The one upgrade every FXT needs Top quality product, perfect fit and easy installation. Pricey, but worth the money. Fitted with an efficient cat. so my social conscience doesnt feel bad for polluting, nor does the car smell. Factory like fit, and stock-silent with the factory cat back, the perfect upgrade for a daily driver. Big power gains in an easy to install package. I'd highly recommend getting new flange & donut gaskets, OEM ones are cheap insurance.

Rated 5 out of 5 by from Great product, but be prepared! I had it in my wish list for a while and finally bought it. I did my research and watched a bunch of YouTube installation videos and ordered all gaskets, bolts and nuts ahead of time so install went smooth. Had to use penetrating oil and torch to break loose turbo nuts and bolts but it wasn't too bad. The whole process took about 4 hours. At first test drive immediately noticed low end torture increase and better exhaust sound comparing to stage 1. I'm very pleased with stage 2, plenty of power and exhaust sound is great with some crackles and pops of backfire. Highly recommend!
