need exhaust,8.8 rear

[jacarc1]

i have a 1985 capri/mclaren and want to change to a true dual exhaust. I am looking for long tubes,h pipe and some kind of performance muffler. I would also like to upgrade my rear to an 8.8. My car came equiped with a b303 cam and head work from the factory. i currently have the stock intake and carb. New to carbs so if anyone has suggestions on a carb/intake upgrade that would also be something im interested in. thanks...john
