My smog pump is making a horrible whine during normal operation so Im going to delete it.
I still would like to upgrade my cat to a high flow 2-way / 3-way one. I understand some do not require an air tube from smog pump.
What is your favorite high flow catalytic converter?
Any other cheap ( under $500 ) upgrades while messing with replacing the catalytic converter you would do?
I have a 1994 F150 300 4.9L I6
All your advice and tips are much appreciated
