[Mr. G]

Back in the 80s I had a local muffler shop install a dual exhaust system on the '77 T/A which was done with the old blue streak glass packs that look to be about three and a half feet long. They cut the parking brake cable during the install and these mufflers are obstructing the cable being reattached. I am considering going to the H.O exhaust manifolds and the Gardner 2 !/4 " dual exhaust system for the car and was looking for comments from members who have done this system on a '77 T/A. Also looking for recommendations on who make the best H.O manifolds as I will need to buy a pair of those also. Car has the Pontiac 400 and stock 4-speed trans. TIA!
