Not a 4.9, I know but looking for a little input.
89 f250 460 4x4 5spd
Headers to a y into a single 3"
keep the 02 sensor, no codes
no cat, glasspack
straight out to a turn in front of the wheel
Get rid of the stock restrictions maintain decent scavenging, not looking for huge power gains but should help some, maybe even up mpg a bit. Any thoughts? Thanks, Matt.
