I 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 RepliesAbout 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 RepliesI have a 95 f150, Eddie Bauer, extended cab, 4x4, 302, 285 tires. My question is this... What happens if I remove the second cat. I am trying to get a better sound from the exhaust and have been told the second cat is making that impossible. There is no o2 sensor downstream of the second cat, so I'm thinking the computer will never know its gone. Also how well this affect power. With the bigger tires, it's kinda sluggish off the line.
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 RepliesThe truck in question is a 93 F-150 X/cab 4x4, has 5.0 5spd. So yesterday i replaced my exhaust with pre made magnaflow "y" pipe/cat with a flow master 44 then new pipe all the way out. When i start the truck up this morning to let it warm up a little it started to give off a funny smell almost like brakes/electric burning smell. I was wondering if this is common for new pipes to burn off any oils that may have collected on them from the factory. I look under the truck and nothing is touching the exhaust, but the shiny new pipe is starting to change colors. So do you think it will go away in a short time? I have to an appointment about 30 miles away on the freeway think this will burn off?. BTW there was no smell prior to the exhaust change.
View 1 RepliesI am thinking about changing out the whole exhaust system heads all the way back to replace my annoying glasspack setup that came with the truck when i bought it. its a 95 f150 5.0L im thinking about getting hooker headers [URL] .....
And that's as far a i got because i want duel outs but don't know what kind of cat i need and what kind of muffler. and even more which brand of muffler because i want a really deep tone but not extreme loud. How to put this exhaust system together?
I 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 ?
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 RepliesI was running errands yesterday, left the car for an hour, then got back in and noticed that the deep rumble of the exhaust that I love was suddenly gone. The car seemed fine when driving, but the wookie growl only showed up for a few moments. No CEL. What could be causing this?
View 1 RepliesI 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 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 RepliesSo I finally went and put the exhaust I had been wanting on my truck. Pretty simple set-up. I had the factory muffler cut off and a flowmaster 40 series on it previously. I liked the sound under load and at cold start but normal driving I could not tell a difference from a factory muffler. So I had the flowmaster removed. I still have 4 cats so it's not crazy but it is loud. The only time I have cackle is on initial start-up not even at WOT which was a pleasant surprise. I just like the look of a single exhaust but still want some sound. I have been gone awhile as I needed a little break from starting and also being drawn in to arguments.
View 7 RepliesAfter 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 purchased my 2008 Explorer Ltd about 4 months ago with a 4.6L and 63k miles. I use it for towing a small travel trailer, so I don't put many miles on it. It's got about 66k on it now. According to OASIS, it has had all MFR maintenance performed up to the 60k mark.
In the past two months, it has developed a "sound" on startup. it goes away after about 75 seconds. To me it sounds like a typical exh manifold leak. That "3 cylinder, putt putt putt tractor" sound. There is no apparent affect on performance. It is definitely coming from the area of cyl #1. I have a recording here.

It is the "higher" of the sounds. The lower pulsing/whooshing is just regular engine noise. You can hear the regular engine noise as the camera pans to the back of the car.
What puzzles me is that the exh manifold sound goes away after 75 seconds or so. Holding the tailpipe shut for a bit builds up lots of pressure quickly. Do you think it IS, in fact, an exh manifold leak, and it seals up with thermal expansion as the engine worms up (75 seconds)? Is this a typical issue with the 4.6L
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.
Having a sound from my exhaust. Basically when the car is rolling along around 25 MPH or so, and my foot is not on the gas, as soon as I gently touch the gas pedal, I get a soft "thump" sound. This basically tends to happen in 5th or 6th gear only.
The previous owner had done a muffler delete on the stock exhaust so I figured there was some sort of back pressure issue because of this.
Finally out of frustration, I sprung for a new Borla Catback exhaust system, hoping to eliminate this issue. While the thump sound is slightly less, it still happens!
I am changing the passenfer side exhaust manifold on my '00 150. The bolts all came out fairly easy, sprayed them often in PB over the last 2 days, my problem is the 2nd and 3rd nuts on the bottom are under the motor mount. Do I need to remove that or is there an easier way that I'm missing.
View 11 RepliesI have a 2004 f150 LAriat supercab 5.4L triton with 120,000 mile on it. Without good reason, I let the dealer convince me to put new plugs in it. Ever since, I've had a serious smell in the cabin of gasoline and or exhaust, and a 2MPG drop in MPG. At first it smelled like gasoline. I took it back to the dealer and they said a connector had backed off, which is code for I don't even want to know what. They "fixed it" but the smell remained.
They then changed the rings on the fuel injectors. The smell got better, but there is more of an exhaust smell now. I checked many blogs about it and found several bloggers with almost the same exact situation. I suggested to the dealer that they need to check that the proper spark plugs were used and they were correctly seated. They of course confirmed this but God only knows if they actually checked.
I also looked up to see if there is a cabin filter on this vehicle and there seams to be some disagreement on the blogs about this fact as well. Now that the cold weather has arrived, I prefer not to take the cowl off or check the plugs myself until it gets a little warmer. The smell is noticeable most of the time and especially stopped at a light regardless of the heater or air conditioner. Should I be more worried about the smell or the fact that I actually took it to this dealer in the first place?
When I start my truck in the mornings. In 20 seconds + -, there an exhaust "pop". I'm assuming its to warm up the turbos. The manual says to warm them up before driving. The engine is an engineering marvel, unlike my Cub Cadet that has a plastic hose to push in the oil drain and the filter don't have a hole in the metal frame for the oil to run into the catch basin. I hope that engineer dies a slow painful death
View 8 RepliesHad the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. So I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?
So I was wondering where the O2 sensors are on the 04 f150s and if I could cut the rear set of cats out without throwing off those sensors?
