The COBB Turbo Back Exhaust System for the 2008 and newer Subaru STI hatchback. This much anticipated exhaust uses a unique straight-through muffler section rather than common chambered designs, which minimizes tubing bends, reduces back-pressure and keeps sound output below SAE standards. The outstanding craftsmanship and attention to detail are evident in every aspect of this full turbo back exhaust.

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 Extremely Impressive :) First off - Cody and Jared in customer support at Cobb HQ are extremely helpful and friendly - they have an unlimited pool of knowledge about absolutely everything that you could even think of. I purchased this last week after about 10 months of having my '14 WRX completely stock. Like others, I also spent endless time on youtube listening to sound clips trying to figure out what was going to be the best sounding exhaust for my rex. The exhaust note that comes out of this is not even justified by any video that I have seen - the depth of the tone is incredible at WOT and ridiculously quite with a subtle deep tone from inside the car when just cruising around. Install was a little over an hour by myself, the longest part being putting the car up and getting all the bubble wrap off of the new stuff(everything is extremely well packed). All in all it is absolutely worth every cent :)

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 Worth every penny! I listened to a lot of exhaust systems before purchasing this one. I DIDN'T want a rice burner sound. I also DIDN'T want an annoying drone sound going down the highway. Like others who have reviewed this product it sound amazing with a deep tone. It doesn't have that raspy sound or have a drone sound at any RPM range. When you punch it though WOW! Definitely recommend!

Rated 5 out of 5 by from Amazing sound and power I Bought this system and couldn't be happier. I installed it with 3 friends and it took a full day. Install was really easy and simply. The hard part was getting the old down-pipe off as well as the heat shields. Had to take the intercooler off the top but it was well worth it. I Love this product and would recommend it to anyone who is looking for an exhaust. It isn't too loud when idling or highway driving but when you switch it into sport sharp and floor it, it sounds unbelievable. There is slight backfire when you step on it but nothing too bad. Overall, this is an amazing product that I would recommend with the stage two tune by Cobbs accessport.

Rated 5 out of 5 by from Perfect sound! I've had this catback for 6 months now and I am still amazed at how perfect it sounds every time I drive it! Its very noticable, but never too loud. Absolutly no drone at any speed. Looks great and fitment was perfect!

Rated 5 out of 5 by from Install was a breeze and sounds amazing!! So I bought a used WRX that had some mods done to it including a cat back exhaust system which was an assault on the senses. I was looking for something a bit more reasonable for exhaust note and didn't make my ears bleed on the commute. This COBB cat back does the trick, install took maybe 1.5hrs by myself. Its exhaust tone is amazing(may have giggled like a school girl on test drive), the sound test video posted here nailed it. Only thing I would like to have had come with the kit was gasket and hardware to replace the connection at the downpipe. Overall, super pleased!! Great craftsmanship too!
