I own an 84 TA. I'm going to be replacing the 305 with a L98 from a '92TA. I'm also ordering TES shorty Headers and eventually a cat back exhaust. My aquestion is, 1)would I need to buy the header bolts separately, or do they come with the Headers? 2) would the Y-pipe come with the Headers, Exhaust, or neither (I have to order it separately)?. Thanks for any replies.

 

The TES headers come with a y-pipe and bolts.
