@xluben ahhh okay. Learn something new everyday. Thanks (y)

@ShawnSubaru Yes, the downpipe (exhaust immediately after the turbo) is what free's up the power on this car. It will require a tune, but you should see significant gains in power. The cat back makes very little difference in power, but a significant difference in sound. Even on a 400+ WHP setup, the stock cat back exhaust does not pose a significant restriction.

@TheDAnKMiLk Better!!! lol, pretty equal though!

@Ollie100111 Precisely, a cat back is after the catlytic converter, cuz some cars have resonators and some big canisters that quiet the flow, so a cat back is a common mod for sound, and might free up a couple of horsepower. If you get a full exhaust, you have to retune the car, like fastflat4 said. All cars are programmed to run a certain way, taking out the cat, makes it run different and can mess up the car if the car isn't retuned.

@ShawnSubaru Okay. See that is the best explanation I've heard. And so a "Cat-back" retains the catalytic converter and just changes the rest of the exhaust from the catalytic converter "back?"
-
@Ollie100111 Of course bro. Exhaust free's up the flow of the heat from the engine. Air comes in, there's an explosion, and then there is exhaust. All car's from the factory come with restricted exhaust so they run cleaner, and they all have a catyltic converter, which is in a sense, a filter. Taking it out free's up the flow and makes the car faster

The Hatch is the best looking Subie.

sounds perfect, I want mine to sound like that! Quick question, is the cobb downpipe you installed catless? Also does it bolt right up to the SPT exhaust or do I need an adaptor?

@garrettej8 The COBB downpipe is catted. It does not need any adapter to be installed on the stock or SPT exhaust.
