Diagram of airflow?

Does anyone know where there is a diagram of the exhaust system in a WRX. Like where the air comes in and what it goes through untill it leaves the exhaust. I know I saw one somewhere before.

Thanks for that link, I read it through, it has some real good info. One question I have is whats the difference between getting a DP and a catback exhaust over getting a turboback exhaust? Doesnt a DP and catback cover everything from your turbo back?

A downpipe and catback is a turbo back.

Cobb used to have a really good one on their site but I haven't been there for a while to verify if it's still there. cobbtuning.com & go to the tech articles, then exhaust design. Good info

If you go to www.google.com and do an "image search" and type in something along the lines of "WRX Exhaust diagram" you'll find a couple. That's how I found them atleast.

Thanks. So is there any benefit of getting a Turboback or mixmatching a DP with a Catback with a different company? Would a turboback perform better than a dp and a cat from different companies? Or is it mostly just preference. I was planning on getting a downpipe and a catback, but I might just get a turboback to make things easier.

The only thing to watch out for is the mating of the DP to the catback. There are two different types of flanges used, a donut gasket style, and flat flange sytle, you want to make sure they are compatible before purchasing, or you may have to do some messing around with to get them to seal. An easy way to elminate any question of whether they will mate is to buy an entire TBE as a set.
