I have decided to install a Clifford heated intake and Clifford headers on
my inline 261. I am now needing to decide on how best to plumb the exhaust
for best performance gain. I will be installing an Edelbrock 500cfm
4-barrel. It has been suggested, for best performance, that I bring both
headers together into a single 2 1/2" pipe using a Flowmaster muffler and
continuing on with a 2 1/2" tailpipe.
What thoughts do you have on the best way to go. I am not looking for loud,
but do want to see a performance gain with all the new hardware.
Thanks,
Stephen
