Big problem!

I just bought a 1992 EB 2 weeks ago. I finally get it inspected and the place said it was real bad. They are too busy to take the time on it . But they said was there was a hole in the cat. Can I convert to a single aftermarket cat? Also they said all my brake lines look like hell. Can I find pre made SS lines. I can settle for regular ones too. Just can't seem to find any. The ones that go all the way back not hoses. The truck is spotless inside and has a 60k Jasper engine in it. I have another 92 EB and love them to death. I just don't want to throw this one away. It real rusty underneath cause it sat in VT a long time, but nothing a little roll on undercoating cant fix.

You should be able to remove the cats and run a high flow catalytic converter. might want to see if you can take them to the yard, someone told me they're valuable, something about the money in them?

i'd go back though, and find out what fails/passes and work from there. as for brake lines, i don't think there's any premade, might have to make/bend them yourself.

True.

The inside of OE cats are made of Platinum. That's why OE cats are usually more expensive than the aftermarket stainless steel high-flow variety. Just a fun fact.

Your local auto parts store may be able to help with your brake line issue. If nothing else, they can usually give you some ideas of what to do.

Other than that, you could try a salvage yard. It's usually fruitless but, sometimes you get lucky.

I also live in Md, and know what a pita state inspections can be. Make sure you get a detailed list of what they failed before figuring out your next steps. Regarding brake lines... you cannot buy pre-bent ones. You need to buy straight lines and bend them yourself. Most auto stores carry them and it's pretty easy to do. I suggest you start soaking your bleeder screws with PB Blaster since you will need to crack them loose to bleed the system.

Ok so I found out that the shop was being a dick. It's not that bad under there, the rockers psyched them out. The brake lines are kinda bad and need to be replaced and I got my boy doing that. The rockers are going to be from LMC. Anyone know the size of the exhaust so I can take care of it?

For the stock 4.0L v6 I would go 2.25" - 2.5" any larger diameter and you lose torque. For a decent, better flowing system, you are probably looking at anywhere between $150 and $400 Depending on style and completeness.

(Make sure the system stands up yo your states specific emission standards.)

 

[marragtop]

Keep in mind that for Md inspection, it will need to be air tight.

We have a very stringent emissions test in AZ. Same as California's. I have been able to pass with a single, aftermarket converter with no problem. If they are real picky I suppose they could give you a hard time for not having two. Here, they just look under with a mirror to make sure it's there, and run the test.

You could also try and score some from a boneyard in a state which doesn't have rust problems.

I recently replaced some rusted out brake lines. The one that runs from the RABS valve to the rear axle was so bad that it was leaking. I bought some assorted lengths of coated brake line at NAPA and some brass fittings to go with them. Rather than run a new line all the way up to the RABS valve, which is in a hard-to-reach spot, and has a metric fitting, we cut the line halfway up the frame rail and ran new brake line from the rear up to that point. We also replaced the line that runs from the left rear brake to the "T" on the diff. Also replaced the rear flex hose as a precaution because it was starting to crack. If you need, I can send you the NAPA part numbers.

You will also need a good flaring tool and some practice with it. (That's why I took mine to a friend's house. He has a bigger garage, more tools and more experience).

Here, I don't have emissions test. So Im not worried about that, just need a cat. It can be hollowed out for all they care. But anyone have any experiece with the gibson side swept cat back? I might as well get a cat back when I get the new cat put on.

 

[seth247]

gibson is usually too expensive for me but I hear good things.

If you buy the muffler your self(cheaper) then a muffler shop will usually run the pipe for 100$ ish. Got my dual system piped for 75$.

I don't knownthat kind of sound your looking for but 2.25-2.5 is the norm for the v6's.

 

[HahnsB2]

I'm also running a single aftermarket cat and it passes with very good numbers. Don't hollow it, it sounds like ass and doesn't gain you anything.

 

[Shen2187]

Yeah, DO use a cat though. The back pressure it creates is what gives you torque.

 

[68amc]

I would never hollow it. My friend did that :thumbdwn:. I was just stating that MD wouldn't care if I did. Ok so I need 2 1/2 in. pipe from the cat back? Then just get the shop to bend it and install it?

 

[Shen2187]

Yep, either that or get a cat-back kit from Flowmaster for a few hundred bucks.
