How can I install dual exhaust on a 1994 F150

I would like to install dual exhaust on a 1994 F150 with a 302 & a auto trans. It currently has the stock exhaust with y pipe and one o2 sensor. I would run true duals with a cat. and muffler on each side. will i need a o2 sensor for both sides or can i use one. thanks

The 1st thing I would do is get a set of cheap shorties from a 87-93 mustang to replace those sorry manifolds with. I used Mac equal length, but I would suggest mac unequal length due to the time spent with plugs and boots. They will bolt right up. Then you can run 2.5" pipe for the rest of the system with a set of magnaflows or Hooker Max flos having crossover pipe installed also. Neither have drone in the cab, have very good HP flow / flow ratings and are relatively quiet until you get on it. The 02 sensor will be ok in 1 pipe though.

Good Luck,
David

If I were you I would go with a set of headman headers. They make a set of long tubes for the F-series body style. They are only about $120.00 and from what I hear they work great on a stock or slightly modified truck. Summit Racing part numbers for the Hedman Long Tubes (HED-89270)

I had a set of Flowtech Long tubes on my first truck, a '90 F-150 with a 302 and an auto. The exhaust setup I finally settled on was a true dual system, with 3" pipe from the headers back, an Xpipe custom bent, and Hooker Maxflow mufflers. I was getting it setup to handle BIG power, but found my '93 Lightning instead.

Looking for just about any 5.4 4v parts for the truck.
