request for information on mac headers
[font size="1" color="#FF0000"]LAST EDITED ON 14-Oct-01 AT 02:03 AM (EST)[/font][p]I am considering putting a set of mac headers on my 92 351 windsor s/b 4x4 regular cab. I am begining to hear the sound of an exhuast leak at the manifold and I am looking for some options.I have read that the cracks in the maninfold are due to exccesive temperatures due to restrictive exhausts.I am considering installing mac headers and a three inch cat back flowmaster system or a dual side split flow master.The truck has lots of jam but I would like her to breathe better.I installed a K&N filter and saw some milage improvements and better throttle response.I beleive that improving the back end will also give me some performance gains.Any info will help
Thanks djblue.
