With the downpipe installed we turned our focus to the exhaust system. It features a full 3″ cat back section that feeds the exhaust flow in to the center of the muffler where it gets split by a reversed Y merge to output on the sides of the muffler.

| Here you can see the 3″ piping flowing through the stainless steel perforated core resonator. This feeds to a 3″ 2 bolt flange that secures the piping to the muffler. The exhaust fits very well and provides nice clearance around the factory heat shields. We have not experienced rattles of any kind. |
 |
| COBB used the minimal amounf of bends to route the piping to the muffler. The stock piece has a much sharper bend and enters at the side of the muffler which is an open baffle design. The COBB piece uses a reverse Y merge to smooth out flow to the 2.5″ muffler outlets. |

| Cobb then uses their own tips to finish off the muffler section with OEM like fit and finish. The hangers, muffler housing, and the quality of the welds are all first rate! |
Just like the downpipe the exhaust was a breeze to install as there was minimal swearing and I wasn't left bleeding afterwards. Honestly, I was rather amazed at the ease of the whole process. The only problem I encountered is that Cobb has you re-use the OEM donut gasket, this will work perfectly on lower mileage and non-daily driven cars, however living in the proverbal buckle of the rust belt caused the gasket on our car to crumble in to pieces when we tried to remove it. Easy enough, we procured one from our local Subaru dealership and back in business. We finished the install by checking the torque on all of the bolts that were touched during the install and finally by thoroughly cleaning the downpipe and exhaust piping of all fingerprints and grease. We wanted to make sure that we achieved that nice golden hue when we first heat cycled the new exhaust setup.
