I love it when folks throw around expressions like this
What exactly was the huge difference??
dynos over and over show net gains of 12-20 hp when going to even race headers on a chipped but otherwise stock 3.2, usually closer to the 12 than the 20, there is a huge overlap in that data set w/ the data set of setups using stock exhaust w/o cat or w/ a sport cat and some sort of muffler.
in other words most of the gains are coming from chip and cat changes not from the actual piping changes.
