This downpipe optimizes turbocharger spool by enabling faster exhaust gas evacuation while maintaining emissions compliance under federal EPA standards (except California). It supports forced induction setups without sacrificing engine performance or triggering emissions warnings.

Note: Not legal for use in California per state vehicle code sections 27156 and 38391. Federal law prohibits tampering with emissions control devices; this part meets EPA standards for aftermarket repair or replacement.

Seems a bit thinner than my last two, but they did come together for the price of one. Seems to be of good quality non the less. Fits well in my 2014 Subaru forester
