Stock Exhaust I really haven't been under m car yet to look at this. I was wondering what kind of exhaust the stock 94 Z28's had? Are they true dual? The reason why i'm curious, is because I want to get a general idea of what I have. The person I bought it from said they got flowmasters on it. I got the cat removed, but on a standard flowmaster exhaust set up, it can't be true dual unless I get headers, right? Also, when I choose to get long tube headers and the Y-pipe, should I get a high flow cat with it for back pressure, or just leave it all out? I want the car to run at it's best performance with the headers, but at the same time I want it to run good driving wise.
Thanks

The stock exhaust is not a true dual setup. The exhaust runs from the manifolds into a Y-pipe, cat and into the muffler. It just has twin tips coming out of the muffler. Just because you get headers does not make it a true dual exhaust setup. Since you have the Flowmaster Catback I assume, if you are going to get some LTs and a Y-pipe.

I was thinking about getting headers soon, althogh I want a true dual exhaust set up. Should I just wait until I get the longtube headers, then make it true dual? Or should I just get the headers and hook it up to my current exhaust? I have a flowmaster on there now, so I'm assuming if I get a true dual set up I won't be able to use that same flowmaster, right? So basically when I get the headers If I want true dual, I'm going to be spending a lot...Also, when I decide to get the headers wouldn't it be wise to get the matching y-pipe? If not, it will make things weird, right? Now, If I get the matching y-pipe, do I have to make my car true dual exhaust or will it bolt up?
Sorry about all the questions. I'm trying to get this all right.

1.) You can have true dual exhause with stock manifolds, shorty headers, or long tube headers.
2.) You only need a y-pipe for single exhaust (that is what you have right now). All a y-pipe does is combine the exhaust from each of your 2 headers and combine it into one (hense the name Y-pipe).
3.) No you will not be able to use the same muffler
4.) You do not need a catalytic converter on any combination of systems as long as you have a way around emissions.
5.) If you stick with the exhaust you have now, you will need Y-Pipe and headers (suggest Hooker Ceramic Coated Long tubes and a Mufflex Y-Pipe). If you go True Duals, you will need Headers and a true dual system.
Opinion: Don't waste your time on Shorty's or True duals, Get long tubes, no cats, and the same exhaust you have right now. That is what I have and am very happy with it.

By the way, I was thinking about getting some pacesetter Lt's. Are those bad or something? Everything else seems so expensive and people tell me they like the pacesetter Lt's. What do you think and what kind of Lt's do you have?

With the mods you have there should be no difference in hp between single and dual exhaust. I could see that duals would be beneficial if you had a stoked forced induction motor with 700+ hp, but for a fairly stock motor, there will be no difference.

So, what do you think about the pacesetters? Should I go with it and keep the flowmaster or...? How much are bullet mufflers anyway? I want to get the best thing for my position, but not waste money. You know what I mean?

For the mods that you have, the brand of Headers you use (hooker, pacesetter, etc) will not be that much of a difference as long as they are all long tube headers. I would have them coated no matter what (unless stainless steel).
I don't know what you meant by "should I go with the Pacesetters, or stay with the Flowmaster". I thought you were talking about Pacesetter headers, Flowmaster is the catback. There are 3 different parts to your exhaust system.
1.) Headers (long tube or shorties) or manifolds (stock)
2.) Y-Pipe (only used for single exhaust)
3.) Cat back exhast or dual exhaust system.
People usually only use bullets on a dual exhaust setup. "Bullet" is not a brand name, it is a style of muffler. There are many different manufacturers of Bullet mufflers and they all vary in price.
Best thing you can do "GET LONG TUBES AND A Y-PIPE" Hook that up to your single Flowmaster Cat Back and you will be set.

I think what Omaha was trying to say is - If you are going to be doing more extensive mods in the near future, such as cam, heads, n2o, etc, then wait because otherwise you will be getting tuned twice and wasting money. If headers, cai, cat back is all the mods you are planning on doing, then go ahead and get a tune, it will help you out.
Personally, I would spend the money elsewhere because I think you will notice more performance mods with other things. (i.e. clutch or torque converter, throttle body, mass air, etc.)

Yeah, but if he gets LT headers, delets AIR, or does any mods that require the PCM to be modified, he mind as well have other things done as well. It's only 50 bucks for a 2nd tune after 60 or 90 days from Ion. If he gets a torque converter he's going to have to have the PCM modified. Throttle bodyies and mass air are useless until you make a lot more power. The stock ones are fine.
