If you need a new catalytic converter, this is the one for the 2.2 , a full 2” ID mandrel bent pipes so no crimps , and a high flow catalytic converter

It sure woke up Oldblue, it had a 2.2 and this down pipe with the Walker cat back , it let that 2.2 breathe!

My 2009 has the pipe with two canisters; I see that covers up to 2007 it says. I searched their site, but apparently they don't make one for 2009. Or will this also fit mine? So far, knock on wood, I don't need a converter.

Are the 2 1/4" different from OE? Is the Walker pipe 2 1/4"?

They "fit". It is the 1 or 2 cats that makes a diff.

Some people modify their down pipe by gutting that second cat, some eliminate it . Depends on the state laws.

This one is for the 2008 thru 2011 dual catalytic converter
