I have a 97 F250LD 5.4 4wd, and am wondering if anyone has replaced the catalytic converters with aftermarket ones, and how successful it was. Also, what was the price, and what product was used?
To provide some advice, I have not had to replace my cats on my F-150, but I replaced one on my 97 Explorer, and will be able to answer all your other questions.
I had a Check Engine Light report that one converter was bad. Ford dealer quoted me $1500 to change both converters on my Explorer. I went to http://www.discountconverter.com/ and bought the one I needed for about $200 with shipping, (I would imagine F250 might cost a little more, but most likely less than a dealer would quote) and had my mechanic install it.
That sounds like my experience, I cracked my y-pipe and crushed my converter on my f250 during a work related off road excursion. The total from Ford to replace both was north of $1400. My mechanic bought a high flow cat that meets California requirements and reworked the y-pipe with his over the top welding skills for about $500.00.
TOO LATE !!! Today I had my local muffler shop replace my entire exhaust system. I went with two dynomax high flow cats(1 per side), into a single inlet/dual outlet dynomax stainless ultra flow muffler. It is dualed out behind each rear tire using aluminized pipe. After driving it home (50km), I haven't had any engine lights or anything else go wrong. It sounds awsome out the back, yet it is still quiet in the cab. As a mater of fact, I can't tell if there is any increase in cabin noise cruising down the highway. Just what I want. All for $1500.00 incl. tax !
Not sure if its got more power. Sounds like it does !
I wanted to do that same thing with my 98 but magnaflow said it would make the idiot lights come on. Keep an update on how it all works out after you run them for awile.
