See, there’s the problem. You cannot guarantee that it’s the same catalyst with a CARB number slapped on it. Non-CARB legal catalysts won’t clean the air like OEM and won’t last very long. CARB-legal catalysts are OEM replacements.

Where are you getting your prices? A dealer?

Welcome! I used to live on the west side and now reside in the valley.

One with pedals.

Anyone can claim that they are an oe-style cat. The only real way to know if an aftermarket catalyst performs in such a way that it conforms to EPA pollution guidelines is to have it CARB certified.

If it is the EXACT same part inside and out, then you are paying for the CARB certification which can cost millions.

It probably isn’t the same catalyst inside of it, and the old catalyst would not clean up the exhaust to OE standards. Now that it is CARB-certified, it will. More platinum, more money.

You’re thinking CARB (California Air Resource Board). CAFE is Corporate Average Fuel Economy, which is a weighted fleetwide average of fuel economy for each manufacturer.

Because aftermarket cats do not do anything to clean the exhaust.

Lol, no. I nuked my 12a as I was arriving at DGRR11. Beat the car all weekend on one rotor and only had to tow it home after a wheel bearing failure destroyed my spindle.

I’ve heard that the N54 suffers from early (70-80k) turbo failure, but all that before 30k? Wow...

California is starting to install multi-spectral cameras with viz-band cameras on highway on-ramps and offramps to catch people that do this. The multi-spectral cameras can measure pollutants coming from the exhaust and then they use the viz-band cameras to take pictures of the license plates.

This is my plan for when my e39 525it when the 6cyl stops passing emissions. Whatever is the most current eRod engine + appropriate transmission.

Can you give us a rundown on the problems with your 335d?

I rode in Honda’s minty fresh 2005 NSX-T press car a couple of years ago. Aside of not fitting in it, it was a fantastic car.

It’s a piece of shit.

I’m going to catch a lot of flack for this:

I’ve seen quite a few Z8s since moving to SoCal (mostly along PCH while riding and they’re parked in driveways), along with an Alpina autotragic version at the La Jolla Concours. I hate the way the Z8 looks in person. It’s ungainly.

I tried it and chrome insists that I repeatedly log back in to ensure that I’m me. I put in my password and it goes back to the same screen.

I commented to my wife that she was sucking the life force out of him, and my wife was like “Dementer Kiss...”

Priceless.
