I just found out that Random Technology makes 3.5 and 4" cats, so maybe this pipe dream will become reality...Now i just wonder how much this converter will set me back...

Well, it's good that you found someone who makes
them. I have the 3" Random Tech. cat on my Camaro.
It's $250.00! So, I bet the 4" is about $300.00! Maybe
more.

Wow 4" cats.. This could bring out a few questions
Im already thinking of a sweet exhaust system now.. But not a 4" catback system.. But the 4" cat could work..

Regards to the emissions comment.. What are you exactly relating this to? the diameter of the Catback or the cat itself not being designed for our cars? Remember have facts before you can qoute that Just for get..

I think camaro_nut was talking about if I could not find the larger cat, that I may have had to run w/o one.

I am thinking about having a custom 3" y-pipe made up, that goes into either 3.5 or 4" to the cat, and then runs to my 3.5" catback. Do you think a 4" y-pipe and cat would be too much, or should I just try to stay with 3.5"?

Four cylinders flowing into twin 3" pipes? Why do you need that much y-pipe for a 350 engine? Your 1 5/8" header pipes will restrict the exhaust more than a 3" y-pipe will. What is it you're building here?

My headers are 1 3/4" SLP's flowing into custom 2.5" y-pipes into Magnaflow 2.5" cats, then into a custom 3.5" I-pipe, a 3.5" race muffler, then narrowing down to 3" into a Magaflow f-body muffler with 2.5" outlets. In my opinion, the only reason to go larger than that is if you have a larger engine, or you're running a high boost turbo or blower. But what do I know?

Lastly, you should have asked this question in a separate topic. This topic is for updating the FAQ pages and providing more info about what I said in the first post, not for asking questions. Thank you.

You are very wrong and miss-guided. Maybe you should practice what you preach and do a little reasearch on exhaust systems and how they work.

Please don't school me, as I am not prepared for the embarrassment. Please get rid of the caps and refrain from spouting off meaningless jargon without further explanation. What are you trying to teach us?

I bought the edelbrock kit for my 89 RS but I ordered the ones for the TPI cuz I wanted the 3"Y-pipe. I will fab up a hot air tube for the air cleaner. As for the rest of the exhaust I'm gonna use a 3" cat and a 3"system but undecided which muffler I'm gonna use. I'm NOT a fan of Flowmaster so either a dynomax muffler or a spintech. I may try Edelbrock's new SDT muffler.

Anybody use the edelbrock headers?

Ive got the tubular exhaust nickel plated edelbrock exhaust. Im curious to what you mean by ordering the ones for tpi? I know theres the system for dual cats or single cat, but i thought all tubular exhaust sytems were all the same. Are you running the tubular exhaust system or no?

the TBI system uses a smaller y pipe than the TPI system. Also the TBI system has a provision for the thermal air cleaner heat tube, the TPI system does not. I wanted the bigger y pipe so I ordered the TPI system.

Yes. You want to order the TPI setup so that you do not get the stock sized 2.25" y-pipe. Everything else is the same on them. ALso, all 3rd gens used a single 02 senor mounted in the driver side header/manifold.

I have it and love it. It sounds nothing like Flowmaster
and I have gotten plenty of compliments on the sound of it.
The drawbacks are the price, especially for the dual
outlet system. I don't have a good sound clip yet, but
I am working on it.

I dont know if this was said or not but the air pipes are only there and along with the pump is to pump air down into the cat to make the car warm up faster and get a little better of performance.

So if I order headers through summit for a 82-92 5.7L Camaro, will I have to weld in a o2 sensor? Or do most designs for our cars alreadly have one welded in? Looking for a header for a mid 300 HP (TPI) 90-92 Camaro. Any suggestions?

I have set of Mr. Gasket headers but they have a 2.5 inch collector(inside diameter), but I'm afraid thats too small. ???????

Hedman Longtubes are pretty good for the price, but I'd get the elites(model line that's just ceramic coated) as they aren't that expensive either.

If getting longtubes and you have emmissions regulations in your state(especially if they do a visual check) then you will not pass. You also have to custom fab a y-pipe for longtubes. Depending on what enging/setup you have I'd just go for hooker shorties pn. HOK-2055. Unless you are running a fairly modded 305, or a mild 350, I doubt that you would like the results that longtubes would give you.

so i read through this thread and have a question and 2 comments,

Q: what is an I-pipe?, is it just a single pipe exhaust?
comments: first off, anybody who has thier cat on because they dont think that 5hp will increase thier performance is not enough
