My friend has a "305" 1984 GMC C-15 pickup. He wants to know who makes reasonable priced headers and complete exhaust systems (smog equipped) for a reasonable amount of money (works at walmart so not a big budget). The reason I say a "305" is that it has a 6" tall air filter, and after observing some other things (including a very throaty exhaust note), i'm wondering to myself if it still displaces 305 cubic inches.
