Ford Exhaust :: 1997 F250 - High Flow Cats Performance?
May 7, 2008
Would a high flow cat on my 97 f250 7.5l make any more performance and would it make it any louder? My truck has the air tubes on it so its hard to find a cat for it.

I am getting my truck back today after all the work that has been done to it over the past 3 weeks, and well, I have always wanted to gut my cats, but have been worried to waste the cats buy gutting them and didnt want to cause a disturbence in the airflow by gutting them, so i figured atleast if i was aching to be illegal and gut them, the least i could do is just remove them, but my question is, will it mess the o2 sensors up? Currently the o2 sensors arnt connected to the cats at all, so my feelings is it wouldn't mess with the truck or would it? I was thinking of just removing the two cats in the true dual, and replacing the segments with pieces of pipe, would that be sufficient?

My truck threw a CEL after the first start today. The CTS reports it twice. I noticed it about two minutes after start.
P02E1 - Diesel Intake Air Flow Control Performance
The air box gauge is green and it doesn't reset when I push it so that appears to be fine.
The one thing I can easily notice is the sound of the turbo. Typically when I stop and park, the turbo spools up, then down, then spools again and gives a sigh of relief and it's then silent. It's not doing that currently.
Now, I can hear it constantly when parked and it spools down after I turn off the engine, even two minutes later. That is not normal for my truck when I wait for the above to finish its routine. When I start the truck, the turbo immediately spools to where I can hear it which is also not normal, as if it's building 0.5 psi. I realize that's funny to say on a turbo diesel but I know the sounds of my truck. The EGT's are fine, EOT, ECT, TFT are fine and I can build boost when driving without issue. I took the drive to work easy this morning so the highest I noticed was 10 psi.
I restarted the truck after a 20 minute drive to the office and it didn't clear the CEL. The CTS squawked four times when it woke up the second time but it didn't show me which PID it was upset about.
I'm thinking this has nothing to do with the CAI and this is something downstream of there. EGR related? I haven't opened the air box yet, at work and in dress clothes so that'll need to wait. My past four or five regenerations all started between 1.94 and 1.97 soot gpl. That is also not normal and is something I have been keeping my eyes on. Currently the DPF is at 2.10 so it has made it further. Normal behavior (post emissions flash) is above 2.54 soot gpl for an AR.
Ford Exhaust :: 1997 F250 4.6L - Rumble At Idle
I want to put a flowmaster system on my 1997 F250 with 4.6L engine. The muffler shop says i won't get alot of sound out of it because of the OEM Cat Convertor on it. Is this true? I'm not looking for something that will rattle the windows a mile away, just a nice rumble at idle and a good tone when accelerating. The muffler shop suggests a 3" in and 2.5" duals out using a 40 Series muffler.

View 2 RepliesFord Exhaust System :: Position Of Muffler In The System Affect Performance?
Was just mulling over redoing part of the exhaust system on my truck. As it stands the original y-pipe is still intact but some bozo reduced the rest of the system down to 2.25 inch with an ancient glasspack for a muffler. Maybe he thought it would net some kind of benefit, maybe he was just throwing together parts from his backyard. Either way it's going, I'm planning to keep the Y-pipe but step it up to 3 inch with a Flowmaster chambered muffler and I just suddenly wondered if the position of the muffler in the system affects performance. If I put it directly after the Y-pipe the exhaust pulses would hit it sooner...
View 14 RepliesFord F-150 - 1997-2003 :: Rough Idle And Poor Performance - Code P0401
97 4.6.. So it would appear that I have the wild goose chase of codes. The major symptoms are rough idle and very poor performance. I started off by cleaning the egr valve and ports. Then I checked the egr valve itself and watched the valve open and close under a vacuum. I was suspecting the DPFE sensor but I wanted to trying something else first. I was under the Impression that if at idle you apply a vacuum to the egr valve it would cause the engine to "stumble and stall". I did this and there was no change in the way the engine was running. So now I'm lost as to where to go from here.

I have been thinking about toying with my exhaust. I don't have a crazy amount of money. I got a 94 F250 with the 5.8 liter 351. Heres what I was thinking. Get rid of everything after the cat, and then run a single 3 inch pipe from the cat to a flowmaster 40 series, and then exit either right before the back tire or right after it.

Ford Super Duty (1999-2016) :: 2005 F250 - Code P0721 - OSS Sensor Circuit Performance Fault
I recently picked up a 2005 f250 SD 5.4 4x4... I was having issues with sporadic shifting and wandering shifts while cruising around 100kph, scanned it and came up with p0721 OSS sensor circuit performance fault.
I checked the harness and all looks fine, now I attempted to remove the OSS at the rear of the tranny, got the 8mm bolt out however could not, for the life of me get the sensor out. I tried not to use pliers to twist the sensor or anything for fear of breaking the sensor off and having bits go into the transmission.
Ford A/C :: Fan Sounds Like Its Blowing Hard On High But Air Flow Seems To Be Restricted
My fan sounds like its blowing hard on high but air flow seems to be restricted some. I have noticed a sound of the fan hitting leaves in the past. I just don't know how they get in there. It still cools good but air flow is nice when the temperature is close to 100.

Ford F-150 (2004-2008) :: High Flow Catalytic Converter?
It is true that, for a supercharged engine is beneficial to have some back pressure in the exhaust? I have a 2007 FX4 whipple supercharged, 5.4L, 3V, no cat, true dual X 2.5 ", I have no tailpipe emissions problems in my country, my problem is the power to the wheels. I install a high flow catalytic converters?.
The Magnaflow 94106 is what many people recommend but in this forum, people from Bear Rivers says he does not meet the high flows, what is the correct part number.
I have a 4.56 ratio 315/70R17 tires and power makes lose significantly?, is this true?. I have a big question, in particular point 1, because I think I lost torque at low rpm and, according to what I read, maybe this escape as free to be affecting the successful performance of the engine.

I have a 2005 F250 with an intermittent AC problem. I had noticed over the past year that I only had high or low fan when adjusting my AC. Recently my AC has intermittently just not started blowing any air when I turn it on. When this occurs, I can put the fan on high and hear the clutch engage, however no air flow comes from the vents. I did some searching around and didn't find an answer. I was curious, where I might be best to start troubleshooting.

My wife's 97 f150 4x4 had an exhaust leak on the passenger side. 7 out of the 8 bolts holding the manifold on are snapped off. 4 of them are snapped off 1/8" below the top of the hole on the cylinder head . I am I unable to get a drill in to drill these out. The other 3 I've tried welding a nut on these but they won't budge and I wring the nuts off. If I have to pull the head(something I don't want to do)can I just pull that 1 head or do I have to tear the intake and everything off?
