I’m goin to be installing an exhaust cutout and I was wondering what the stock exhuast pipe size from the cat to the muffler

Hey guys. New here. Recently became the owner of a 2003 Eddie Bauer 4.6 V8 Explorer. Whoever owned it before me messed around and changed the muffler to a “raptor”. I’m doing so they removed the tail pipe and made some very sloppy welds. Also removed the flange from the cat and welded a straight...

New Pipe added - Post Cats removed

Off w/ the Post Cats

2002 Explorer 4.6, if read tons of stuff about exhaust for them but I haven' found a real answer on something. If you were to remove the cats, replace them with straight pipe then installing the o2 sensor in the same relative spot would the system work with no CEL? And with that being said...

I took my Explorer in about 1 year ago with a noise underneath when in reverse. Dealership determined PTU issue and fixed. It was still under warranty/ess than 60k. This past week, the vehicle started the same noise, again (now at 89K). Plus, a really bad odor and leaking a fluid (which I forgot...

hey all, over the weekend i replaced the stock catback exhaust with the gibson aluminzed cat back system. 08 ST first off. My experience in summary is that this thing is not made for the sport trac. it is just extremely close to fitting.... (assuming their is a frame length difference in the...

Hi, Can anyone tell me if this is normal? I bought my 2017 Explorer brand new about a year ago. The car is garaged both at home and at work. I live in Southern California so I don't have exposure to rain, snow, ice, etc. I typically walk to work so I have few miles on the car (about 7,500...

Hey everyone, So I installed a thrush welded muffler to the 4.0. While it sounds much better with the added growl and low rumble it still feels a bit quiet, it maybe added 40% more sound and gave it a sick tone, upper powerband is definitely improved, highway driving is much better. Im looking...

I am toxicologist who joined the forum so I can share information on how to test carbon monoxide (CO) levels in Ford Explorers and the drivers of Ford Explorers. #1. If you can smell vehicle exhaust, odorless CO is always also present, but CO may be present even if you do not smell exhaust...

So I was fixing this... and I noticed this... how would I even go about fixing this?

Hey! I've been wondering if deleting the resonator on the V6 will make a big difference in sound, of course it won't have the big, mean sound of a V8, but I'd like my truck to be a bit louder than it is currently. What all would removing the resonator entail? I'd like to keep everything in front...

Forgive me for posting this, however, I'm the epitome of a beginner... I just want something with a little bit more rumble than stock... I also don't want to cut anything. What size inputs can I fit stock on my 1997 4.0L SOHC V6? Sorry again for my incredibly stupid question, but thank you for...

The main question I do not see asked is this. I have a 2017 Ford explorer sport 3.5L Ecoboost. Has anyone just removed the resonator and left the factory mufflers and if so what did it sound like? Did it resonate in the cabin or drone? Has anyone put a Magnaflow 18" a larger magnaflow on a...

So was working on my Explorer last weekend, wanting to change out the EGR Valve, as it is froze and rusted. Well I was trying to get the one nut off, and I ended up breaking the EGR Tube off clean at the nut down at the exhaust. So I ordered a new EGR tube, and am ready to put on the new EGR...

So I have a 99 explorer 5.0 limited. I want the exhaust to be louder and better but I want to be able to quiet it down when I want. So I was thinking dual exhaust cutouts. First off what is the diameter of my exhaust??? And I was thinking of the best placement.... I want it after the cats. But...

Hello everyone! I just did a head job and with that added Pacesetter headers to my OHV engine. They dont seem to line up perfectly with the y pipe. Has anyone had this experience before? Do I just need to get better bolt and torque them down as hard as i can? Also can anyone confirm that there...

Hello, everyone. I recently discovered that I have an exhaust leak just behind the O2 sensor on my 2000 OHV. I've seen videos of this repair on other vehicles and it seems straightforward. I'm just wondering if the stock bolts unscrew, or if they're welded on and have to be cut off. I'm seeing a...

Just failed PA inspection due to an exhaust leak at the exhaust flange between the extension pipe and the end of the catalytic converter. The inspection place recommended two flange repair kits bolted together and a new gasket to hold the pipes together. What should I know about this process...

2011 EXP LTD BD 06/02/2011. 1000 miles. Burnt oil smell during hard acceleration. This is easily repeatable and happens every time. Well now we have another confirmed issue with my LTD. Under hard accelerations coming from an on ramp and merging with fast moving traffic only. Other wise, all...

Hello everybody, my name is HOOAH and I am the new owner of a 2006 Ford Explorer XLS 4.0 V6 4wd, with 103k. This is my first Ford vehicle and I hope it serves me well for many years to come. I already had a dealer look it over and they gave me the check list that it is ok and all is well. I have...

I just ordered a set of exhaust manifolds from Dorman. In the picture from RockAuto they showed it coming with the OEM type multi layer steel exhaust gaskets but when they arrived they had the graphite type gaskets. Does anyone have any experience with the graphite type gasket on the 4.6? Do...

Good Evening Everyone, So I own a 1994 Explorer XLT, and I just drove it from Seattle to Tempe, and it ran fine the entire time however it started making an interesting noise around the halfway point of the journey. The sound can be described as a rattling or a grinding, and it only happens for...

So on my way into to work this morning, I heard a pop under the good followed by what at first sounded like something was caught on a tire. The nose would slow or speed up with my speed. No check engine light came on, no loss of power. I pulled into a gas station and realised the noise is...
