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 5 RepliesI just got a brand new 2008 F150 supercrew FX2 last wed. I love it, it's my first truck ever and I'm excited to drive it. I wanted to change the exhaust to something that has a low rumble and is deep, not too loud or anything.
View 1 RepliesWould 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.
View 4 RepliesI just bought a 97 F250 with a 5.8 in it. Im loosing coolant somewhere. Did a pressure test it checked out fine, no steam from exhaust, no coolant in oil. Nothing on the ground, it making me nuts. Truck has 182000 miles on it but its clean, no rust and runs to good. I don't know much about Fords but someone told me it could be air pockets. It just got a new radiator b4 I bought it.
View 1 RepliesI have a 98 with the 4.2.The troubles started with popping a little through the exhaust ,bogging down and bucking,rough idle and had the two codes together that deal with having bad intake gaskets don't remember the codes offhand.
I also noticed every plug in the truck was wet and black however it didn't appear oil wet.I have changed the fuel filter,spark plugs,lower intake gaskets,plenum gasket ,injector o rings,checked injector ohms all were 16.5,new EGR gaskets,all bolts are torqued to specs
Now I have a no run condition, it will crank but not run. I heard a pop in the engine one time. I cranked till the battery went dead.I also noticed as I was calling it a day last night the radiator reservoir was empty. I don't know if somehow I got a hydro lock even though I put new intake gaskets in it or i have some other issue like timing or something. I don't know where to look next....
1999 F250 super duty w/ 5.4... My truck seems have issues keeping speed on the interstate like its not wanting to switch gears on time. Its auto by the way. Gotta little hesitation in the idle exhaust due that I have several leaks in my exhaust. Could that be the problem?
View 3 RepliesMy 2003 F150, 5.4L has been having some rough idle/misfires issues both at idle and under load.
I have fixed one big vacuum leak, replaced the PCV valve, new sparkplugs, seafoam and heet in the gas, replaced fuel filter, tested the fuel injector resistance. Coolant levels have not changed. The truck burns about a quart of oil every 1000 miles or so. The white exhaust is heavier than condensation, but it comes and goes. The rough idling comes and goes as well, and it usually happens under load and the CEL flashes.
The codes I get are random cylinders, po303, po308, po171, po174 were the most recent but there have been other cylinders as well. I clear the codes after each attempt to fix it and they come back different.
I notice that there is a small exhaust leak that drips water just behind the engine, and when I shut down the truck a lot of water will pour out of an area just behind the cab on the passenger side as well as out of the bottom of the muffler (small hole, looks drilled).
Usually the rough idle occurs after filling up the tank, but from different stations so I do not think it would be watery gas. I use Heet every fill up as well. Also, there is a sulfur smell after the rough idling occurs (catalytic converter?).
I'm losing coolant have, excessive white smoke coming from the exhaust, and rough idle. Doesn't over heat or even try to overheat. The oil fill cap looks brownish white. It drives fine other than extremely rough idle. I know how to check a blown head gasket with the combustion gas test.
From what I've read blown head gaskets on 4.6 fords are fairly uncommon but a blown intake gasket is fairly common. How can I tell the difference?
After a couple of setbacks, including forgetting to install 3 out of the 4 orings on the oil cooler, I got the IPR Gen2 delete installed. I have a couple of issues since getting it started. I have low boost, I know the up pipe for the turbo is seated well, really surprised about that. However, the exhaust pipe may have a slight leak, but not positive. Finally, the last on this issue, I have a ripped MAP hose that I'm going to replace.
Next issue is that I hear what almost sounds like a gas engine exhaust rumble from the front of the truck. What it could be? I had white smoke initially coming out of the exhaust, but it cleared up after getting everything up to temp and taking it for a ride down the road. On a side note, the leak that I had from my previous thread seems to be gone now.
I recently had my local VW dealership replace the alternator on my 2004 V8 under warranty. Upon picking up the Touareg, there is a noticeable increase in exhaust rumble inside the vehicle as well as a vibration coming from the front passenger's seat and footwell. It isn't any louder outside but my wife and son both agree that it is much louder inside the Touareg.
I brought this up to the service representative and he had the shop foreman take a look. The technician said he didn't find any exhaust leaks and said they dropped the motor without removing any exhaust components. He claimed they just removed the clips on the pipes and dropped the motor and exhaust together. I was left to drive away with no solution.
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.

View 1 RepliesI have a 87 F250 with a 302. Every time I drive it I smell like exhaust. Doesn't matter how short or long the trip, but the longer the trip the stronger the smell when you get out. I found 1 loose manifold bolt and tightend it, but no difference.
View 13 Repliesmy 05 f150 5.4 with 76,000 has a weird rumble at idle, I don't think its a miss and there's no codes and when I put it in park it goes away or if the idle changes just a little you don't feel it. And you feel it through the brake pedal the most its not real bad butb enough to bother me.
View 5 RepliesMy 'new to me' '97 Explorer has this odd 'rumble' every now and then, as if I just ran over some rumble strips. Very brief, maybe a second or less, as if I hit 5 or 6 of those bumps. It is a V8, XLT all wheel drive and I'm not familiar with it. Is this something I need to get looked at soon or is it just one of those things with the AWD. I only driven it a few times so I don't see a pattern and all else is great. Its a tight truck with less than 100K miles and I really enjoy it.
View 7 RepliesI have a 94 ranger 4L. I am looking for a more loud exhaust sound in/outside the truck and at idle. I have had a cherry bomb turbo on it and it was ok but not loud enough for my liking. I just picked up a flowmaster 40 2 days ago and it sounds good but again just not loud enough for my taste and kinda a lot more. I was looking for a louder muffler that is not a glasspack and would like to stay under like 80 or so.
I also thought about getting a high flow cat which i think might make some more sound but was not sure. Im running the stock pipe which is 2" and end in back of the wheel on the right. I look at the Hooker Headers Maximum Flow Muffler which i thought would be louder b/c it's more straight through the muffler so it would put off more sound better. What would u recommend for something more loud ?
I bought a '05 F-150 with a 5.4 with 112k miles on it a few months ago. It had been sold from an auction, looked really clean, and a good price. Not long afterward it started having issues with running rough at idle. That's when I found this forum and began reading. Tried different things but it only got worse and finally had a shop look at it. Cam phasers were not doing well. Not a cheap fix but more involved engine work than I had ever done so I had them do the work.
It ran fine for a few days and then the idle rumble came back slightly and the check engine light (CEL) came on. I read the code and it came back with a number that indicated air flow was an issue. Internet search said to clean the throttle body. Some threads on this site also said do the Mass Air Flow (MAF) sensor while I was at it. Much has changed since I used to work on cars as a kid. Everything has it own cleaner. I cleaned the MAF sensor with MAF cleaner. Cleaned the throttle body with throttle body cleaner (it was beyond filthy) and a toothbrush. Put it all back together (started late and it was dark by now) and took it for a quick run to see how it had improved. Instead of smooth, it started running even rougher, and within 100 yards went into fail safe mode. Now my mood is getting darker. Park it and go inside to watch the Aggies in their bowl game.
Good game but the truck is still running rough and I am losing confidence in my ability to do simpler things on it. I get up the next day and run codes on it. It had three codes all pertaining to air flow or the throttle position. I am thinking I screwed up the throttle setting somehow when cleaning or maybe only put the MAF sensor in upside down (that seemed unlikely since the screws only seemed to line up in one orientation). So I open the hood to check the MAF sensor just in case and find to my embarrassment that, in the dark, I failed to plug the MAF sensor back in. The problem was a loose screw holding the tools. I plug the sensor cable onto the sensor and take it for a ride. It runs great. Life is good. MPG is climbing higher on the onboard display. My confidence is returning even after humbling mistakes. After everything, I still love this truck.
So, now for the tune-up advice. The truck runs well but still rumbles slightly. Based upon everything, I believe it was well cleaned before it sold but maybe not fully serviced. Spark plugs were possibly never done. I intend to do a tune-up on it but do not know what has already been done so I'll assume almost nothing. The air filter looks brand new. The serpentine belt has nicks so that will be on the list. I am thinking of changing the following:
Spark plugs
Spark plug boots
fuel filter
serpentine belt
PCV valve
Oil was changed when the cam phaser work was done. So the advice really boils down to a question:
Is there anything else I should consider changing or doing or cleaning? I have not worked on cars much in the last 30 years but am beginning to enjoy it again.
About 4 weeks ago my 2015 sports turbo developed loud exhaust, deep rumble, dealer replaced left rear muffler. Noise still there. I'm suspecting the center muffler.
View 5 RepliesMy 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?
View 1 RepliesI have an 07 F150 with the 4.6L engine and i was wondering if theres any need to clean my injectors at 30,000km the truck seems to vibrate at idle but not very noticeable seems like a regular v8 rumble but two ppl have pointed it out recently and have riden in my truck a bunch, should i be puttin some injector cleaner in my fuel?
View 3 RepliesMy wife's Explorer 4x4 has a noise in the front at around 100km/h. It is not detectable below 90km/h. Its not noticeable from a standstill until around 100, then you hear it a little. I find I can make it more noticeable if I vary my speed from 110 to 105 up and down, then its easier to hear. Once you get below 90 km/h you cant hear it at all.
I have a broken leg right now, and I normally do ALL my own work so I'm a little-limited mobility wise at the moment.
I'm suspecting a wheel bearing. I put the Explorer in the garage and my son jack up both wheels on the drivers side. I started the engine and SLOWLY accelerated up through the gears to 100. I know the hazards with this as I've done it with other vehicles, but this was the first 4x4. Then we jacked up the passenger side (after lowering the drivers side) and did the same thing. I could slightly hear/feel the rumble when the passenger side was jacked up.
I did drive the vehicle on my outdoor ramp/pit so I could use my crutches and get underneath to have a look. I grabbed the cv axles and they feel solid. The propeller shaft was replaced last year, and the cv axles look brand new. (bought the vehicle off a friend two years ago.).
So, are my suspicions correct, is it the pass. side wheel bearing? The Explorer has 294000kms. Never did test it on corners as I didn't want to swerve back and forth on the highway with the amount of traffic.
