1994 Z28 Headers and exhaust

So, basically, if I go headers into cat-back, I'm doing it because it's cheaper and will pass emissions. If emissions is a non-issue, then would you still say cat-back anyway, or would you then say go with duals, and screw the AIR, EGR stuff altogether?

You can get headers with or without emissions fittings. The work is a bit more involved if you opt to remove the emissions stuff. Block-off plates must be installed and the AIR system must be removed, adding marginal cost to your already high labor expenses. Not to mention, some shops may refuse to remove emissions components.

Long tubes + GMMG catback FTW...
true duals are not needed and will provide little to no performance gain over a well engineered catback for a bolt on car.
Also, if emissions are not an issue, ditch the cats, EGR/AIR pump garbage-then you will not need the fittings on top of your headers...By doing this it makes the engine bay a little cleaner, drops a few lbs (9ish pounds I think?), and frees up a pony or two.

I would agree with that, that is a lot of flow.
I would recommend something besides a slowmaster, no one here uses them. Hooker aerochambers, magnaflows, bullets of some sort are what most use. I don't know how much I would listen to someone who is telling me to put flowmasters on.

I would still recommend going stainless if the OP intends to keep his car for awhile, and is willing to spend up to 1K for his exhaust system. That's just me. I'm not a fan of things that rust.

Yes, Mufflex, and possibly others, offer systems larger than 3", but based on what I've seen, the vast majority of aftermarket catbacks for these cars are going to be 3". I probably should not have said "if not all" because I knew that wasn't true immediately after typing it. $hit happens when you're in a hurry.

I would get some cheap EBay stainless headers if the LPP's put him over his limit. If he's not going to do the labor himself, that's another issue entirely, and a point that I overlooked. In that case, I would recommend he buy all stainless and do the labor himself. It ain't rocket science. But,that's me, and I'm just throwing out alternatives. It never hurts to know all of your options.

Thanks for all the posts guys. I should say that my goal is/was to keep it under a grand. In reality, I could spend a little more than that. Of course, I could buy the headers and let them sit til I'm sure I can afford the cat-back. (Which seems to have officially be deemed better than duals lol) Also, concerning the labor, I assumed welding was involved, but even if it's not, I'm not sure I could find the time to do it myself.
However, if it's really as "easy" as some of you say, I suppose I could get the car up on some ramps and have a look-see. If I can clearly see what needs to be done, then I might possibly try to do it.
I have an old 89 Camry that just needs a new control arm. If I made that my primary project, then I could drive that while I work on putting the exhaust on the Camaro......

Hmmm, that's a good point. Plus if I get under there and can't figure it out, I could always resort to plan A, or get someone to help me.
So, do headers and/or a cat back system require welding at all?
