    Red face WRX exhaust 3" to 2.25 adaptor?

    Hi. I'm new. I've googled high and low for an answer to this question with no avail. I purchased an HKS catback and want to install it, but my OEM cat is 2.25. The inlet on the exhaust is 3". Where can I find an adapter for this? I don't want to cut and weld anything because I purchased the exhaust full turbo back, which I will install when I can tune the car. For now, a catback will work fine.

    What do I need? Sorry if I overlooked another thread on this subject, I couldn't find anything.

    They should have an adapter for this where you bought the exhaust. It's an often used part, readily available. It re-uses the doughnut seal and needs another gasket for the flange side. Should be available from where you got your exhaust.
    You can't have everything - where would you put it?

    There are adapters for the downpipe to stock CBE out there (Rallysportdirect.com) has them...but I haven't seen anything for the other way around...

    ...though I suspect it shouldn't be a problem anyway. I've mated numerous CBEs that were 3in directly to the downpipe without any problems.

    You shouldn't have to cut/weld anything at all.
