- Purchased this 2003 Ford Expedition 4x4 EB edition a few days ago. First thing I always do on a vehicle is get the intake and exhaust improved flow. The exhaust is fairly simple and budget, cut the old 40 pound boat anchor muffler, install light weight free flowing muffler, add a nice looking tip to back up that great new sound and done deal. This budget exhaust mod was cheap and will pay money back with improved fuel economy, low end torque as well as power increases. Of course more go from less pedal than before. The muffler single chamber inline 2 1/2 IN/OUT round muffler was only $25 on ebay, the exhaust tip only cost $12. Having the muffler cut off and new one welded on as well as exhaust tip was $70 at a local exhaust shop. $107 budget cat back exhaust system which saves hundreds compared to just buying an entire cat back exhaust system which is not necessary. The only bottle necks on a stock exhaust system is the factory muffler and catalytic converters. Eventually I will replace the 4 factory catalytic converters with 2 magnaflow increased flow converters. Ford for some reason put 4 converters on and only two are required since the cat sensors are behind the first converter and no sensors behind the second converter basically telling me they are not needed to pass the sensor test.

If you want more flow and sound, just cut the secondary cats off, the primaries flow as well as most aftermarket highflow cats. It's cheaper that way, and you can scrap the other 2 cats or keep them in case the primary cats clog/break and you can reuse them as new primary cats.
Second, the stock intake is plenty good enough for a stock engine. It's a decent size and already routed for cold air. Aftermarket systems often don't use a heat shield or seal the filter to the fender for a true cold air source. Also think about this: the engine's air is limited by the throttle, so unless the throttle is wide open, that's what limiting the air. So unless you're at wide open, you won't notice the extra airflow from an aftermarket intake. What I always do is remove or cut out any restrictions, resonators or silencers in the stock intake tube and airbox and that works as well as a new system. Plus, paper filters are cheapest and they filter the best.
Lastly, that hood insulation is mainly to reduce noise from the engine so it helps but not much. I've read it's also designed to melt the holding tabs/clips in case of a fire and drop down to smother it, but I have a feeling after it gets old it won't help, or will catch fire and make it worse, so good call on removing it.
Yes, the secondary cats need to go since they are after the back sensors. I wanted to see the difference in the muffler replacement first. So far, I have noticed a great difference without restrictive muffler. It will be even better when the two extra cats are replaced with pipe. The intake I have modded by removing the small trumpet like bottleneck by cutting airbox to where a good portion of the air filter is open to breathe in the air coming from side and bottom of engine bay. I have removed all engine heat shields from intake manifold and hood to keep underhood temperatures improved by quite a bit.
This is exactly what I want to do, ford was going to make a lightning Expedition called the thunder. There a good video on it from donut media. Great video man
That plastic blanket is there for a reason one to keep the engine more quiet n second is in case of a fire those plastic caps melts off and stays on top of the engine to reduce the fire from spreading if your not sure then you can look it up. Every wire can hold easily up too 150F degrees.
Yes the heat blanket has benefits however, I prefer cooler engine bay temps over potential hood protection. I will eventually add hood vents similar to the Raptor to pull hot air out of engine compartment to keep intake manifold temps lower. After all, you can have all the cold air intake and intercooler and then the intake manifold warms it all up again since its all under a hot insulated hood.
O.K. Matt , I'm buying you a gopro when i next go there !!!! And now you can get here to go quad riding and camp in that ford .
Hey man...I carefully chipped off the black paint around the window trim. It comes off clean and leaves a damn need chrome finish like the Navigators....best thing I ever did, it looks great now. You should give it a go
Good idea. I would like to find a way to restore that black paint or plastic coating.
@@madboostingmadmatt48 I refinished mine a few times but it would always chip. Good luck on the build!
sounds Good Sir, I have the same truck.. I would be interested in how you go about changing the muffler. I have a simular exhast tip.. mine was welded on some years ago and has lost it's chrome shine, How would I go about removing the welded tail tip?
I went to my local exhaust shop and had them cut heavy factory muffler off, weld the new muffler and some pipe in its place. Cut old tip off, and had them weld on my new tip. They charged me around $65 for their time, welding and some pipe since new muffler is much shorter and lighter.
I had a 2007 ford expedition el but I traded it in for my 2006 ford expedition because my 07 had 205,000 miles and now my 06 has 106,000 miles
Merry Christmas.. mate hi from Tijuana BC .. mate the noise of your Exp is the transmission you need to change the oil of the transmission
Are you talking about the ticking noise towards the end of the video? Because I have that same ticking sound and can’t seem to find the source
Yes my 06 expedition was making a noise tak tak tak and I changed the oil of the transmission and is gone
@@arturosanchez7222 The ticking noise is your timing chain slapping against the timing cover. The timing chain is telling you to get ready for an engine explosion. Ask me how I know?
I'm glad I am getting ready for an engine swap soon, then I can take my time and rebuild the original engine as a spare, maybe add some better parts.
Yeah definitely timing
My expedition makes the same noice when my engine is on. Is that normal? Or do I need to tune it?
I really don’t believe that noise is anything serious, my expedition has more than 260,000 miles on it end it amazes me how well it drives. The noise on mine sounds like it’s coming after the engine like around the torque converter area. If it doesn’t get any worse and doesn’t create any problems, will just live with the noise. After all I’ve had other cars where the noises actually were from loose timing chain or a bad timing tensioner. When that engine gets changed eventually I’m going to also change the torque converter which I believe the noise is coming from.
I can hear ur phasers lol. But I like exhaust deal.. i have same year expedition, Wanna free flow to.
Lucky for us the 2000 for a newer have the phasers because there is a three valve engine. My 03 expedition has the two valve 5.4 engine. I believe the noise I have going on is the timing chain and the tensioner or make a noise together. My expedition has more than 260,000 miles so I’m not surprised the timing chain needs some attention. I plan is to installThe 5.4 supercharged engine from the Harley Davidson which has about 170,000 miles versus my 260,000 mile engine right now. It’s a huge engine so I’m gonna have my work cut out for me changing it.
@@madboostingmadmatt48 right..mine has almost 280k miles lol, but has no rust very good body and paint.
Mannnn, I spent nearly $500 to get that knocking sound check out 🤦🏾♂️ mine sound exactly like yours -now I know for certain that I wasted money.
So many things on those engines that can make noises. Timing chain slightly loosening over hundred thousands of miles and clacking on the tensioner’s. The overhead cam roller lifters can make a noise overtime. The way I look at it is if the engine runs good and doesn’t make that noise above idle I will keep driving it keeping oil change is very frequent to ensure just right viscosity. Frequent oil changes are very important for these overhead. Cam 5.4 2 valve engines. I noticed right after a fresh oil change I do not hear that sound until the oil gets older or the engine gets hot like on a very hot day. Parts expand when they get hot and they can make noises. The type of noises depend on the severity. So far that engine has run very well. Even after 270,000 miles plus. Eventually, something will give because an engine that old will eventually give out somewhere. However, keep on driving it nice and easy keep it running, and when it’s time to replace it, be ready to replace it.
Do you have a link for your free flow muffler? Looks great
www.ebay.com/itm/194271402865?hash=item2d3b7a5b71:g:Cv4AAOSwehZfTw5m A great deal for two of them.
The funniest thing is that the exhaust tip is bigger (longer and thicker) than the muffler ROFL. @5:27
Does adding this make any check engine lights come on ?
I had no check engine lights.
Must be from a warm climate..where I'm from you need those heat blankets for it to start
We have winter here too, Probably not as cold as where you’re at
I have liked your videos for a long time, but you really need to work on keeping the camera steady. It’s hard to watch sometimes.
Yes I need a lot of improvement for steady camera handling. I will experiment with things for getting better at it
