If you kept them, you could put your stock catalytic converters back on. Otherwise, let me know the year, model, and engine size of your F-150, as well as the state that you are in, and I will be able to provide you with some part numbers.

The Flowmaster direct-fit catalytic converters that fit your truck are part numbers 2020005 and 2020006. Unfortunately, we do not offer a universal catalytic converter for your vehicle.

Dude who originally bought my truck hacked the exhaust to ****. cut out the resonator and added i belive a 40 series dumped before the rear axel. Very loud and drones all day long. I like the sound it's just too loud and is almost headache inducing at 65-70 mph. I'm gonna either have to add a resonator or extend the dump behind the rear tire or both. May just end up with a new system all together since this is pieced together.

will this work ? its 2.5 in/out.
also, could i just use a resonator instead of buying converters? and if so, do i need two or just one right before my flowmaster 10 muffler?

Although it may have the correct diameter inlet and outlet, Flowmaster does not list that part # as fitting your vehicle for a specific reason. Likely, that cat may not be compatible with your truck's OBDII system. I never recommend that anyone owning a vehicle that came from the factory with catalytic converters remove them, or run without them, as it is federally illegal. I would say, get some cats for your truck, see how it sounds, and if it is still too loud add some resonators or switch your muffler out for a Super 40 Series or Super 50 Series. Let me know if you need any help getting your system sorted out. Good luck!

It will quiet down your truck noticeably, but if it makes your vehicle run poorly, what is the point? I recommend the Flowmaster direct-fit units. Do it once and do it right. It will save you time and money in the long run.

Any way i can order just the back half of this kit? "817691" I'd like to run the pipes out the back and i think that would at least eliminate the drone. If it's too loud at that point i can always have a resenator welded back in.
