Man U better fight for that free engine. Us 04's are so envious of free motors and free cats haha. Do ur research. If out of warranty don't sweat bro are motors are cheaper then most cars to replace and most of the time u can get away with a rebuild depending on what's going on. It's best u take...
My cat is on its way out failed test by a little. So I Need to borrow one, I just replaced plugs and coils so I have a healthy ignition system. And a agency power midpipe u can use while I do the test. Hopefully someone around my area is willing to and can help. Thanks in advance
