Good catch! I guess I had 2007 on the brain....

I'll have a new article on the web site before long that shows the LMM components and describes how the new emissions system operates. I recently got an opportunity to shoot some photos.

I was a little surprised that the new diesel particulate filter isn't serviceable, and that more of the exhaust system is welded together. This might be due to a wish by GM to prevent tampering - though the interconnectivity of the exhaust system and the electronics will prevent much alteration anyway. It'll be interesting to see how the aftermarket responds, and how long it'll take them to produce products for the LMM (or any new diesel).
