What are all the exterior differences between the v6 and v8?
I know of the tail lights, but what else?
Thanks.

Exhaust. Only single outlet per muffler. No chrome trim around door handles and windows.

Uhm.... Not sure what else? If you look at the brakes I suppose you can tell a difference there, aren't the Base model rears not vented?

Plus wheels, the V6 only has 18's and they are twin 5 spoke, V6 has red tail lenses where V8 has clear.

Front view has no differences, just on side and rear.

I think the rims and exhaust stand out the most. The V8 has the GT badge, thats about it.

Someone with a V6 already got the GT taillights...

Look at this link :http://www.pontiac.com/g8/specs_viewall.jsp
