Ford Exhaust :: 1997 F250 - High Flow Cats Performance?

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.

IS F (2008-2014) :: Headers And Long Term Reliability?

Headers will probably be the next mod that I do to my F, I have read a good bit about them on here, but no one really says anything about how they are doing long term ( any issues from heat on engine bay plastics after years of use) or how the coating holds up after years of use as track or DD or just anything else that seems to be an issue over time after being installed.

IS F (2008-2014) :: PPE Equal Length - Long Tube Headers?

PPE Engineering has been getting lot's of inquires from us ISF owners about the feasibility of making an Equal Length Header for the ISF similar to the one they make for the RCF. Since I am a past customer, live nearby, have another vehicle and am a pretty nice guy they called and asked if I might be interested in having my car test fit for Equal Length Headers.

While discussing this with them, I suggested that if modified RCF Headers wouldn't fit, maybe they could accomplish the equal length task by using long tubes. Well, it seems that RCF headers will in fact fit in an ISF, and the headers they built for me were also Long Tube. How sweet is that? But, the EL, LT headers must be used with the PPE Exhaust due to the exit point of the collector.

I went for Dyno testing yesterday, and it appears I lost 7HP at the top end and gained only 1.5 lb ft of torque at the high end. I also gained grunt at the bottom. My Seat of the Pants tells me the car is faster.

I don't know why it ran out of breath at the high end. Nothing else has changed.

PPE Dual Mode Exhaust - With HiFlow Cats

Takeda Intake

As far as sound goes, in the cabin with the exhaust open, the drone remains in the same area (between 1900 and 2100 RPM) but is much lower in volume. I can now carry on a phone conversion (with bluetooth hands free) with the exhaust in the open position. The volume level does increase, however, when under acceleration through that RPM range.

Now the ISF does not have a lumpy engine by any means, but it idle with the old headers, the sound (both inside and outside the car) had a sort of lumpy growling quality to it. The sound is now very smooth, again inside and outside. The harmonics seemed to have changed.

Edit - My wheels and tires have changed. I'm now running RCF wheels with larger 295 vs 285 rears, so wheel weight is up a bit!

IS F (2008-2014) :: PPE Headers Install - Rubbing / Grinding Sound While Taking Right Turns

I had my local race shop install my new PPE headers and how I have a rubbing and grinding sound while taking right turns. They have had the car for a few extra days and they say they cant seem to find the cause of the problem. It rattles on a pot hole, it grinds on right turns and sometimes vibrates on highway cruise control driving.

Ford Super Duty (1999-2016) :: 2011 - Shorty Headers Match Up With The Stock Exhaust?

Looking for aftermarket headers for a 2011 f250 6.2l gas job. I have the famous leak and I want to put something in that isn't going to warp. I was told shorty headers typically match up with the stock exhaust. Eventually going to put in a cat back also so true shorty headers would be sick.

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.

IS F (2008-2014) :: Finding Material Type For The Stock Airbox (black Plastic)

what material is used for the stock airbox? The 90 degree "snorkel" intake tube that is held on by two rivets on my airbox has a tab at one rivet that is cracked. This allows the snorkel to move around and come unsealed from the main airbox. It is "pre-filter" so there is no performance issue, but I would like it to stay in place and look right.

Depending on the material, I was going to shave some slivers from a thicker part of the box and mix it with a solvent to make a paste and apply it to the crack. This will only work if the material "melts" in strong solvents like acetone/MEK. Once it dries, it will be good as new. I have done this many times with ABS and PVC. There is a small gap to fill so simply gluing might not be as strong.

Ford F-150 (2004-2008) :: Taking Off Cats?

I went to a couple custom exhaust shops to see about duals for my 04 f150. they gave me a price all were different ranging from 250 to 480 for the same set up. Cat back flow master 44 series dual out the back. I asked them if they can take the cats off and they said no and it would lose performance. is this true? i saw a couple videos on youtube.com and there was some with no cats. I kinda want to get true duals. So is it possible or not for this truck.

IS F (2008-2014) :: Oil Smell Under Acceleration During High Speed

Under acceleration when close to the limit of adhesion during high speed long sweeping turns I was noticing an oil smell last year. I can't say if it was R, L or both turning directions since its been a full winter since I have driven the car.

I'm using Mobile 1 5w30, a stock air box and I have headers. I'm also running 305 PSS tires, and a pretty well modified suspension. I have no facts to back this up but I am assuming because of my setup that I can get a little more lateral acceleration then most.

I have zero oil consumption, no leaks and good test results from Blackstone. My only thought is that I am pushing a little oil in to the crank case breathers during this hard cornering.

Ford F-150 - 1997-2003 :: 2001 - Welding On Rocker Panels

I'm getting ready to do some welding on the rocker panels on my 2001 f150 supercrew. Just making sure I just have to disconnect ground at battery. Never had a problem before but my neighbor blew both his airbags attempting it on his chevy. He said he had battery disconnected, wasn't specific as to which cable, and was grounding off the door strike which could have something to do with the airbags deploying? I've done it on a 02 chevy with no problems

IS F (2008-2014) :: Rattle In Sunroof Area At High Speeds (65 - 80)

Maybe a week or so ago my F's sunroof at high speeds (65-80) has started rattling. Sounds like there is something loose, and it is clanking on another part. I will be taking it to a dealership or auto shop to have it repaired, or fixing it myself if it is something minor. And its not just a one off rattle, it is constant when at those speeds. Had a two hour drive yesterday and it was driving me crazy.

IS F (2008-2014) :: Whirling Noise When Braking Hard From Very High Speeds Above 100 Mph

I have noticed the last 3 times I hit the brakes really hard above 100 mph ( even 120 mph) I hear a whirling noise coming from either the front brakes or tires. Kind of sounds like when you have really old summer tires on the car and you make a stop on the street . I have heard this on the track the last 2 track days I had. I know my front tires (Michelin PSS) are about 40% worn but are still in pretty good shape.

My rotors are the same that carried me through 6 track days in 10 months and was recently told by the dealership that my front pads need to be replaced sooner than later ( they were installed 10 months ago before all the track work ) and I am assuming the rotors are beat up pretty goo . I will be getting new tires in the next few months and will most likely be replacing pads and rotors at the next scheduled service. The car has 34k on it. Is this normal with Brembos or aggressive brakes?

IS F (2008-2014) :: Coolant Go From High To Low Mark When Engine Started And Warmed Up

My coolant was right below the low mark (it was right above 1k miles ago so it has a slight leak, but haven't checked the bottom core yet, most likely its leaking there?) so overnight it sat and in the morning ive filled it to the high mark and upon starting and warming up the engine the coolant went back to right below low. It doesn't look like its leaking at least not anywhere that fast, is this normal? I gotta check later again while car warmed up etc to check level, but how can the coolant go from being at the high mark to right below the low mark?

Regardless the radiator had previously been repaird by the lexus dealership for leaks, where it should've been replaced. Luckily lexus said they will take a look and replace, but Id rather not go through the dealership.
