I think you are going to get a "check engine light" and your truck won't be able to pass emissions test depending on the state that you live. I have them in a '77 Ford F100, i removed the cats and didn't hurt the engine but my truck does not need to pass emission test anymore. Hope this help

Depends greatly on your engine and exhaust setup. I used this together with my existing Flowmaster muffler to get rid of the "Flowmaster drone" sound. Glass packs have a unique sound quality and we'll reduce the noise compared to straight pipes. If your truck has no mufflers then this will definitely help to reduce the noise. If you have mufflers then these will act as additional resonators and reduce the noise a little more. If your exhaust is damaged with rust and holes then no amount of additional mufflers will quite it down.

make sure you have a real catalytic converter otherwise it is loud. the only other problem is exhaust mounts are lower than stock and I have scraped several times.

This type of exhaust won't give the type of gains. With the big inlets it let your cat breath a little better, so less back pressure. It would help maintain horse part that was previously lost

Its not wise to replace a Cat unless the exhaust system is properly checked for temperature differences between CAT and engine, then from CAT out. secondly the P0420 code is usually a oxygen sensor code sensor code in some Toyota's therefore I recommend you stop by a auto zone or advance outo or even Oriely's and have them check and confirm this code for you, its free. For the ECM it depends on wheather you want to buy it new or used, for new you can check Toyota, auto zone, advance auto, oriely's or even amazom. For used you can check a junk yards like pull apart, wrench it, and others for a used ECM. I hope I was of some help to you.

Not sure, depends on the size of your current exhaust pipe/s. You can however call these guys and ask their advice - Pro3 1-855-289-7763, they should be able to answer your question, then you can buy the Magnaflow through Amazon. I also stopped by my local muffler store and asked for their advice. I paid $118 for each muffler, then installation of $300 for 2 mufflers to be installed cat back style. They sound great!!! Hope this helps.

Personally I don't think that there is a difference, as the tubes between cat and muffler are the same from shape and size. Only the material changes. So my opinion is, that the cat back system makes only sense when you have to change the tubes.And that's how my Mustang sounds after installing the muffler only: https://www.youtube.com/watch?v=7pQZCg91wmo

I had this installed on a Mini Cooper S. The installer had to weld it to the exhaust as close to the Cat as possible, as heat can destroy the O sensor (force injected, supercharged, car). On my car that was about 4" from where the exhaust pipes comes together and 2" before the CAT. I definitely needed the longer sensor cable that came with this kit.

I didnt but i did make sure it was carb comp and that is was the rite size for my cats i was replacing before i added dual exhuast and muffler

I'd say yes - but I don't know for sure. Pretty sure your CATs run at a higher oil pressure than a conventional small block V8 but this sender is supposed to be good up to 80psi. So with that in mind, you should be OK .

Doubt this would cause damage to your sensors. Ive used it back to back with no problems on a 2008 4 cylinder. Probably just have bad sensors.

Hey Nick, mine did not come with any new gaskets or hardware. You will need a new pipe gasket for the cat (cat to pipe) as well as the bolt/springs/nuts to attach the new pipe to the cat. Chances of your current bolts snapping are fairly high, and if they break you will need new ones.

Your 6.4 powerstroke has a exhaust with a DPF system that can not simply be cut off and replaced. DPF systems are connected to your engines computer and require specific engine tuning. You can find some great info at Powerstrokehelp.com on how this can be done with out screwing up your engine... FORD RULES... :)

Im not sure exactly how much horsepower it will ad due to the fact on my jeep I haven't done a dyno test.I have 4 to 1 headers to y pipe to magnaflow cat to glass pack.I have to say she sounds healthy.I would want to say 3 to 5 but that would only be an estimate.what size motor do you have?

You should never put exhaust on that car, so it doesn't matter. But look up the stock exhaust set up and get the right inlet/outlet offset and a shop can fit anything

No I don't believe It will. I think your cat in built into your exhaust manifold.

Definitely a different sound. You'll get more performance with the cat back. And even more from changing the entire system. Muffler will only give you sound difference.
