Exhaust help
Hi Guys and Happy Holidays,
After the holidays are over I'm planning to redo my exhaust. I found a local independent shop with a solid reputation.
I want to go with single 3 inch from the manifolds back, new cat, Flowmaster running through the stock location. Would this be worth the effort and money without adding headers? If if I do run headers I would run shorties, again worth the effort? I worry that with long tube headers I may run into trouble with my O2 sensors granted that there is one on either side of the manifold. Would it be hard to hook up headers to the exhaust say 6 months down the road if I was so inclined?
Oh and also, I was under the truck having a look around and I spotted what looks like another O2 sensor right before the CAT, am I right?
Thanks guys,
Evs

if your talking about "Lucy"

Manual everything and completely optionless! you are going to lose alot of lowend torque and throttle response with 3 inch.my friend swapped to 3 inch on his superduty with a 5.4 and couldn't even break the tires loose aferwards it sounded great with the highflow cats and all but he regretted doing it

If you hook the exhaust up to the manifolds and want to go to shorty headers later it will be no problem. Most shorty headers fit the same as stock manifolds as long as you order them specifically for your truck. As for 3 inch exhaust, I have a 3 incher on my 93 f150 and it runs fine. I can still smoke the tires when I want to. The sound is also a major plus cause 3 inch exhaust gives a mean rumble.

Where I work one of my regular customers had 3 inch straight from the manifold and he said he loved it. I certianly don't want to lose the low end torque since my truck is already lacking in that department.

A big pipe will cost you low rpm torque on a 5.0.. unless you add longtube headers. Even then a single 2.5" will be enough I think. I had a MAC single 2.5" system with longtuges on my '89 5.0 F150, and it went from a weasing slug that could not even chirp a tire to healthy breather that would spin both rears from idle.
There is extra wiring in the harness for the O2 sensors, I pulled a foot or more extra out of mine so they reach the collector O2 sensor location with ease.
