I have a 2001 f-150 4x4 ext cab 4.6 . I am have installed a fipk intake ordered the new 1715 microtuner, and now want to do my exhaust. I live in Canada so we do not have air care where I live. I want to know what the best exhaust system would be. I need torque to pull my small trailer and more horseys. Any advice , also should I cut my cats out????.

 

If you want sound, cut your cats out and run 2.5" straight pipes out under the back bumper with big tips---you wout believe how good it sounds.

I wish Missouri didnt have inspections

 

I have kids I dont want it loud. Need performance and be practicle.

 

Magnaflow catback is the way to go then.
