The headers on a TTA hug the block and almost touch in certain spots. This is because the TTA uses the FWD heads which do not have the extended exhaust port that a typical RWD Buick head has. The crossover is also unique. GM used this head/header/crossover combo to fit the Buick V6 into the F body engine compartment. There are quite a few other pieces that are unique to a TTA because of the heads and headers. HTH
