We're not living in a smog bowl like Mexico City or Los Angeles. The seabreeze will blow the pollution away .

I'm running a test pipe at the moment. I've been debating whether to reinstall my cat or just leave the test pipe installed. On one hand, I noticed almost zero gain in power or fuel economy, maybe 2hp and .05 MPG, and my cat looked to be in good shape when I pulled it. Also, the car now smells like a charcoal grill and got louder because the stock catback has a bunch of rust holes in it that leak exhaust under the car. But the test pipe is a few pounds lighter. And because the cat is gone my floor doesn't get red hot like it used to, which is nice because I usually drive barefoot and the floor used to burn my heel. Decisions, decisions.
