the wife is thinkin about getting a new trailblazer,one with the 5.3. will most the bolt on mods for the tbss fit the reg tb?like headers,catbacks,air intakes?

 

You should tell her she could avoid the confusion about parts compatibility by just getting the SS... They are only a couple thousand bucks different, aren't they?

 

yeah if she is getting a brand new one, hell even a used one, find a SS. 2wd would be cheaper, but AWD is nice.

EDIT: to get the most info, head over to the trailblazer ss forum, so you know what your getting into....
