exhaust 4.0

Hello I have a 98 explorer with the SOHC V6 motor. I don’t have emissions where I live, and would like to cut out the stock catalytic converters. I want a straight pipe setup that’s not loud but still lets the engine breathe more. Has anyone done this before with good results? Or does anyone...

Check engine light came on, found myself with a p0420 code. Should I bother messing around with a new oxygen sensor, or should I take it into a muffler shop and see what they recommend? I've had one of the cats repaired already.

What would be the best option for a bolt-on exhaust tip for the stock tail pipe for my 05 Explorer 4.0 V6? I got two exhaust tips from DC Sports: one that fits up to a 2” outer diameter tail pipe and another that fits up to a 2.25” outer diameter pipe. The one that fits a 2.25” pipe was able to...

What size bolt-on exhaust tip will fit on a 2005 Explorer tail pipe? Engine is a 4.0 V6. I ordered 2 different tips, both are DC Sports brand. I got a black single tip that fits up to a 2” outer diameter pipe which didn’t work. I also got a chrome double tip with a single input that fits up to a...

Local mechanic pulled off one of my heat shields and tossed it; said it was loose anyway/rattling. Said 'not to worry'. Ford seems to have a different idea. I haven't been able yet to crawl under and see which one(s) are missing. There are generic pieces of heat shield(-ing) available at low...

Thanks to all the great advice on this forum my '93 XLT is joining the 'modified' club piece by piece. Got a 2" Skyjacker lift (very nice) and some new wheels and tires. The truck's never been a power house, but is really struggling up the hills these days. I'm looking for ways to add just a...

I need a good aftermarket ypipe for my 2000 explorer xls with no catalytic converters

Hello everyone, I’m a new member to the forum. I have a 2000 Explorer XLT ohv 4.0 . I have 1 week left to renew my plates and I’ve currently got gutless cats . I went and bought two off of a 98 yesterday but the system was different from mine. I had to purchase them because it’s the best option...

Hi, I just bought a 2007 EB with the V6 (I know, I know) and I'm looking at some new mufflers. I really like the flowmaster 50 series, but I'm worried it'll be too noisy in the interior. I don't mind a little noise, but I should be able to talk at a reasonable volume. Also, how easy is this to...

I bought a 2000 Explorer XLS 4.0 today. It died before I made it home. It was slow to accelerate at first, and ran and idled a little rough. I've owned nothing but sports cars my whole life and assumed the slow acceleration was normal for a larger vehicle, and didn't think much of the rough...

Does anyone know if someone makes a 3" mandrel exhaust kit for our trucks? I need at least 3" for my '02 Sport Trac 4x4 due to running 9lbs boost from my supercharger. Thanks in advance

Hi Guys, I am changing up my exhaust from the stock muffler with dual 2-1/4 in inputs to a single output, to one of two ideas I have had. I either want to put two glasspacks leading from each cat (they are only 25 bucks for 26in Thrush's) to a y-pipe and back to my old stock exhaust set...

My 2000 4.0 OHV has a leak in the EGR Valve Tube, it has been welded once, so repair is probably not a good option. I had a garage look at it, they are recommending replacing the LH Manifold, the tube, the EGR Valve, because everything is so fused together. One manifold stud is broken, they fear...
