I had 2 larger additional cats installed. I now have 4...

2 of the bullet style high flow cats and 2 standard larger cats designed for a bit larger displacement motors.

I am due for emissions testing. Though my pcu never set any cel's with the high flows and rear o2's turned on, I was concerned with passing a visual test. Given the volume level my 3" exhaust makes I was certain there was a high possiblity they would check for cats and the high flows hardly resemble cats from the outside.

I also had 1/4 wave resonators installed while I was there.

It seemed noticably quieter but still has a deep rumble. The effect on performance remains to be seen. Boost numbers should reveal any increase in back pressure.

Dropped her off at the shop to get new COP's and plugs. Get her back tomorrow afternoon.

Definitely quieter because the blower whine has become more noticeable @ low throttle positions.

When I get a chance will go through emissions.

How do I get the motor to quiet down?! Geez

Mobil 1 extended performance. Noticeably quieter after the oil change and switch to synthetic.

Cutting off the ignition is the most effective way...
