With the '02 ZO6, the pre-cats are now located in the muffler. The '02 LS1 still has the standard configuration.

So, just out of curiousity, doesn't that mean it's illegal to change your exhaust system on your 2002 Z06 since the exhaust system itself has an emission control device?

I'm sure some '02 Z06 owners are thinking about switching to the upcoming Corsa Ti system for a more aggressive sound.

the 2002 Z0-6 specs says the pre cats were eliminated because of a better cat convertor design. :chevy

Ya I think they don't have the precats because of the better efficient main cat... is this correct? :smash:

Yup, two different sets of exhausts in the parts bin.
I also noticed the new sway bar links. All a cast and
braced alloy. Same on all models front and rear.
