Off Road Y Pipe For A V6 Mustang

junkyardjeff · Aug 17, 2016

I am working on a 84 small LTD wagon that is basicly a Fairmont that has a plugged cat converter,I got looking at it and there are two small converters one on each side right after the manifolds and one after they go togather. Not knowing what is plugged I was wondering if there was a offroad Y pipe available for the V6s,it looks like the Y pipe will have to come off so I can bust a hole through both small converters so I can get it to run long enough to see if there is anything causing them to plug and go from there. Before I do anything is there any way to tell which one is plugged.

That's a good question, there aren't many V6 cars on this forumn.

My "new" car has a V6 in it for now and I'll need to make it run for awhile. I'd kind of like an answer to this one as well.

Let's get some help from the smart guys @jrichker ? @stykthyn ? @Boosted92LX ? @Mustang5L5 ? @madmike1157 ?

You'd probablyhave better luck finding hen's teeth or duck lips than an off road y pipe for that thing. If you have a temp gun it might work to shoot the pipe behind the cats to see which one is cooler. If you don't have a pyrometer gun, bump it with the back of your fingers quickly after a short run on jack stands. That should tell you pretty quick.

Doubt there's an off-road y pipe off the shelf.

Most 3.8 v6 mustangs convert to an h pipe rather than mess with a y pipe exhaust

Let me rephrase the question,are there any off road H pipes for the V6s or Y pipes with out the two small converters

stykthyn · Aug 18, 2016

A standard 302 h pipe should bolt up to it. I'm not familiar with the undercarriage of an Ltd and where the crossmembers go so you may need to do some fabbing. I doubt it's plug and play.

RaggedGT · Aug 18, 2016

why not unbolt the y pipe and let it run for a few mins to verify you have a stopped up converter(s)?

junkyardjeff · Aug 18, 2016

I am going to take a IR thermometer to it and see what one is plugged but they will all probably get gutted,I was hoping to find a non converter Y pipe since it will have to come off any way and could of cashed in the bad ones.

stykthyn · Aug 18, 2016

Why not just cut off the cats and weld straight pipe in its place? This is really kind of a no brainer.

Or replace them with High flow units

junkyardjeff · Aug 18, 2016

Its not my car and want to do as little work as possible.

Davedacarpainter · Aug 19, 2016

LMBO! All the suggestions I've read so far are roughly of equal time.

Trying to find new aftermarket parts for an older V6 is challenging at best.

Good luck, let us know what you decide to do. I'll be interested in seeing it, at least until I swap out the v6 out of my blue car.

Dave all you need is a double hump crossmembers and you can run the factory v8 h pipe.

Seriously? I haven't really looked at the blue cars exhaust yet.

I will need to make the 6 run for awhile, hummm.....

All the cats will get gutted after I find out what ones are plugged first.

Soo, If you are going to gut them all anyway, why waste time trying to figure which one is plugged? Just pull the pipe and beat the guts out of them if that's the plan..

junkyardjeff · Aug 20, 2016

I want to see if its just the big cat that is plugged before yanking the Y pipe off,I really do not want to mess with the bolts at the manifolds if I do not have to.

RaggedGT · Aug 20, 2016

You have a welder? Cut holes-gut converters-weld up holes= no bolts to worry about breaking

junkyardjeff · Aug 24, 2016

Took a IR thermometer to them and it looks like all three cats are dead,going to gut the big one first and reinstall and see how it does before attempting the bolts on the exhaust manifolds.

Chicks can make things hard if they’re inspired...

It's only an inch or two. What's the big deal?

That is…until I whipped out my Bissell

I want to measure mine. It doesn't look that tall.
