No high performance American Pony car is complete without a set of Hooker AeroChambers. Unlike most of the competition, Hooker gets it right by upgrading the classic sound of a small block Ford with a deeper tone and no resonance. We go for sound quality not quantity. These mufflers are constructed of a light weight 18 gauge 304 stainless steel. They are finished off with a brilliant vibratory polish. The competition is going to know you are running a set of Hookers from four car lengths out. Included are polished stainless steel inlet pipes that make this muffler set a direct, bolt–on replacement for the heavy, ugly factory cans. To finish off this high performance muffler set we have included welded, polished, 304 stainless steel, 3.5” tips with a slash cut. The Hooker logo is engraved at the end of each tip so wear your colors proud.
