WRX CAT and CAT Back in my OBS

Post by biggerbelly »

Well I need a new Cat because its broken at the rear. would a WRX cat work? I can get the complete exhaust system for $100. I know its 2-1/4 compared to my 2" but that can be fixed. I am basically concerned about the o2 sensor fitment. If I can get the cat to fit, then ill use the cat back also. Thanks

Welcome to the BBS.

Not sure I follow. Are you looking to cut up the WRX exhaust so you can replace the cat on your car?

What year is your OBS?

I can't say for sure , but most likely you can get it to work. Your most likely gonna have to take it to a muffler shop unless you have a welder. But most Subaru exhaust systems usually are pretty similiar. You might have to cut, reweld, extend, etc, but im pretty sure you can get it to work.

Josh I think what he is saying is he wants to replace his old cat with a WRX cat, and IF HE CAN, use the whole WRX CBE as well

people say that you need to extend the mid pipe by about 6 inches.
