best for 305

    i have an 86 jimmy, thanx to stephen for my solving my earlier problem, i'm considering headers or catback dual exhaust which would be best for slight power gains and if headers they too obvously will be duals, w/ two chamber mufflers?
    also i'm putting on an open air cleaner but my existing stock one has two lines, ones the pvc whats the other one?

    I just put true dual exhaust on my K5 as well as a open element K&N filter and it made a big difference in power. I'm sure I would have gotten even more power with headers but I ran outta money [​IMG]
