Does anyone have the Borla 17183 header in their Subaru? I’m planning to install it on my Forester and also changing the exhaust system because I got a nice offer from 4 wheel online. Any thoughts on this header? Thanks.

Headers without mods like cams on an NA engine are not worth the expense.

 

O.

You won't see any performance gain, but you'll get more of the classic "subaru rumble" from the exhaust. There are cheaper header options in eBay that get the job done just as well.

I have an Ebay replica on one of my EJ22's and it works fine. Again no real difference other than exhaust tone. It was a cheaper alternative to a factory y-pipe for me at the time I built the car.

I too run an eBay knock-off. from what I've noticed, a lot of people who run headers have problems blowing the gasket between the headers and the upstream cat because the headers collect in a size larger than the cat pipe. Let me say this though- there is ABSOLUTELY NO performance gain. None. I don't care, it sounds really good. I turn STi drivers' heads in my bondo'd 97 Legacy. The headers add that nice Subie rumble, however you will not notice it until you put a muffler on. Im running a Magnaflow 14832, and it sounds great.

 

So again, these headers have no purpose other than noise. 

Thanks for the tip on the muffler.
