1978 Pontiac Trans Am
1977 Bandit Trans Am Flowmaster
1977 Trans Am Special Edition, TA 6.6, 4 speed. After battling numerous header problems including reoccurring Exhaust leaks and mufflers bottoming out (scraping pavement) I went back to a crossflow muffler. I installed a Flowmaster 80 series muffler and I am happy with the results. It's not a true dual Exhaust but it works for me!
