replacing exhaust manifolds on my 2008 f250 super duty got a broken stud on right front top tried to drill it out but there's no room somebody said to weld a nut to the broken stud but if I do this will the weld mess up the aluminum head.
View 1 RepliesSo i replaced my IAC(Idle Air Control) Valve and the idiling is much better! However my shaking/jerking has not stopped. I have found the problem which is the exhaust manifolds! I was wondering if when i replace them which i am probably going to get headers should i use metal gaskets?
View 14 RepliesI 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 7 RepliesCan't put it off any longer. Cold start I am getting the exhaust leak at the manifolds on an '01 V10. It's worse on the passenger side than on the driver side. So, I know the bolts/studs fatigue and snap off causing this. With my luck probably flush in the head. So who has done these and how bad was it? If I'm going to do this I am going to swap in a set of shorty headers instead of installing gaskets.
View 14 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 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 Replies.What would happen if I had a muffler shop turn my stock exhaust into a true dual exhaust system with 2 magnaflow mufflers on my 6.9L N/A diesel?
View 5 Repliesis there a set of headers for my 2008 f250 5.4 rwd that will install somewhat easily without me throwing tools across the garage? I see a lot more options for the older trucks. I have a pretty annoying exhaust manifold leak and I figure I might as well throw some headers on if im gonna be in there. I really want to go for sound rather than power. I think I saw a set by flowmaster that looked decent.
View 6 RepliesI have a 2008 6.4L F-250 and occasionally when I come to a stop I can see a faint white smoke coming out from under the truck and the hood. The smoke has a heavy diesel exhaust smell. When I step on the pedal nothing comes from the exhaust and it does not happen all the time. What is going on?
View 2 RepliesI have an 2003 Explorer 4.0 and I am looking at replacing my muffler. Only problem is I don't know who to go with. I am looking for a mellow tone with minimal interior noise. I have been looking at Flowmaster, Magnaflow & Dynomax although I can't make a decision. I have heard how the 4.0 Ranger sound's on Magnaflows website(sound's OK) aside from all the horrible sound clips floating around that don't have good quality to listen too. I was looking at Flowmaster 50 series Delta Flow and there SUV muffler(a tad thicker than Delta series) but want some feedback on who/what to go with. Also, right before the tailpipe ends, next to the spare tire underneath, there looks to be what looks like a resonator if I am correct on the tailpipe. Can this be removed and replaced with new piping? Will it hurt performance or make the exhaust sound different?
View 14 RepliesI tore it apart and there was no gasket or donut ring in the flange. Is there supposed to be a gasket or donut ring? I can feel the leak with my hand. I have retightened & it still "tick-ticks" real bad.
View 7 RepliesI have a 93 ford taurus 3.8L V6 automatic GL. The exhaust clamp between the resonator and exhaust pipe came off and I need to know what size clamp I will need to replace it. I think it is a 2 inch but I am not sure.
View 1 RepliesI have a 90 bronco with a efi 351w and im missing one nut for the manifold to exhaust pipe flange. I have looked all over the net and can't find the size I know its a 1/2in socket but I need the thread pitch and size, had the parts guy try to sell me the stud and nut kit seem really expensive for just a nut and to install the full kit I have to pull skid plates and the trany supports just to start to get room to do the job, seems like a lot of work to replace 1 nut...
View 1 RepliesI just purchased a 2003 V10 with 270 000kms. The truck had had regular maintenance. It has an exhaust leak and runs a little bit rough. Could the exhaust leak cause the truck to run a little rough or am I dealing with another issue?
View 2 RepliesMy F150 exhaust seems rather quiet when I first start it up, but after it gets warmed up good, the exhaust is much louder (which I like). I started wondering if I had a crack up front that widened out when it got hot, so looked under it when I got home today with it hot and still idling, but didn't see any cracks. Also I did not hear any noise like a leak. All sound was coming from the side exit pipe. So... what is the phenomenon that would cause this?
View 5 RepliesI have a 97 Expedition with the 5.4 engine and 160k miles. Recently while having other work done I was told that I had an exhaust manifold leak due to broken rusted bolts.
View 3 RepliesLong story, I'll try to make this short, 2000 E250 5.4L What would or could happen if the catalytic converter was removed from the exhaust system?
View 5 RepliesOk, probably about 1/3 times i start my 96 f150 4.9 with true duals, the left pipe has a higher pitched howling noise, its a steady tone whether I rev the truck up or not it just gets louder. It will do it for about 6 seconds and then stop. The truck doesn't run badly because of it, but i took her to autozone to get her scanned and they said that the oxygen sensor on the first manifold bank has a slow response on startup. Is that what causes this strange noise, I don't even know how it would make it, it sounds much different from the engine. The right pipe doesn't do anything.
View 9 RepliesLeaking exhaust manifold? The truck has a much louder than normal "knock" when accelerating. At first I thought and had some bad fuel in the tank. I eliminated that with a full take of good fuel and some STP but the "knocking" continued. Then I thought that perhaps it wasn't firing on all cylinders but it felt like it had full power. I took it to my mechanic and he said it as a exhaust manifold leak. He said that he has never replaced the exhaust manifold but that it was a "nightmare" and expensive. He also said that it's not a safety issue but on the long run the leak would cause the truck not to pass its emission test. He said the problem was with rusted bolts that would be difficult to remove.
View 12 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 ?
My truck just started running really loud when it's cold and the leak goes away when it warms up to operating temperature.I did a little bit of investigating and I have found where the leak is coming from at the end of the exhaust manifold where the donut gasket meets the catalytic converters. It appears that the bolts rotted that hold the system together at the gasket. What should I do to repair this? I don't really want to replace the whole manifold because I know I'll break a stud off in the engine because everything is pretty rusty down there. I even took some pictures of the problem....
