These were installed on my brothers 306 supercharged mustangs for all of 30 mins got installed here in conyers at conyers muffler shop, drove to emissions place, then back to conyers muffler and had them cut off and removed after it passed emissions.

my brother paid about 100 bucks each for the cats, and install was 50, so 250 to get a car to pass emissions pretty much... now they are sitting in the garage as he no longer needs the car to pass emissions as it is now emissions exempt.

the cats have been cut off, but are definitely use able to someone needing some cats, and dont have the money to pay for the direct replacements.

$150 obo, as stated above, used for 30 mins tops. not broken or damaged in anyway, besides they've been cut off short by danis (sp) at conyers muffler..
