pontiac has alway had a problem with the exhaust manifolds, I bought a new 87 GT fiero when i got out ouf high school and withen the first 3000 miles the exhuast manifold had to be replaced and by the time it had 30.000 they had done it two more times for free, the last time they replaced it they used a 88 model manifolds because the dealership said pontiac had a defect in the older models, the 88 gt manifolds were a more stronger they said. after that i didn't have any problems from cracking. till i rolled the car down a clif lol
