I mean I would advise against removing a cat...

It'll add some rasp but with the V6 it should still sound nice.

Replace mid-muffler and pre-muffler with a Dynomax Bullet. No need to mess with the cat if it's still good.

You guys crack me up:hahano: I have two cars with no cats. One just passed my state emissions test fine, they didn't even notice or check. If your car smells that bad its running wrong.

I passed with a gutted cat and a resonator in place of the cat w/ no problems. Some of you just need to keep up on your maintenance.

In what states are you still passing?

Sounds sorta far fetched

the great state of Arizona. I could post a pic of the test results. The test is just a scan check of the OBD monitors & codes and gas cap check.
