Should I do headers and then wait to do exhaust or can I do exhaust then do headers later on???

Question

I want to re-do my exhaust on my 79 blazer, it has a 5.7 350 in it.

I want to run a 3" exhaust, I bought a magnaflow carsound 3" cat and a Flowmaster Super 44 3" as well. Can I do the exhaust and wait on the headers, or should I do the headers and wait on the exhaust? Or should I wait a few months and do it all at once???

Answer 1

do it all at one time, it will be less expensive if you do.

Answer 2

All at once will give you better results. Less likely to have something in a bind from trying to make something fit a previously installed part.

Answer 3

you could do the exaust but i woudnt i would do everything at the same time but you cant do the headers first the flow will be wrong
