    V6 SOHC straight pipe

    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...

    P0420 2nd Gen OHV help

    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.

    Those pesky heat shields...

    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...

    Exhaust Questions

    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...

    Ticking engine, exhaust in cabin, now it's dead

    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...

    EGR Valve Tube Leak

    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...
