Catted y-pipe vs. ORY
Catted y-pipe vs. ORY Ones cheaper, one isnt. One says eff emissions, the other tries to comply with them. Ones pretty loud, and the other one isnt so loud?
basically what im going after is if i was to get longtubes, which one would be better?
if i got longtubes with the air/egr connections and a catted y-pipe, would i have any hope of passing emissions? is the sound muffled with the catted y moreso then the ory?
ive got alot of questions, help

The sound is much more muffled with the catted Y. I had a ORY and put cats in it for emissions.. I later blew out one of the cats and had to take it apart. To save my self the headache of doing that again I just bought another ORY and put it in. I have the catted Y in my garage incase i need to pass emissions (I was exempt last year) I would think you would be able to pass with the idea you have. I did with a less legal set up then that but I dont know if they really did it.. ethically.. which I dont care how they did it, I passed.
I would say the ORY is better. IT sounds way better and you may gain 2hp if any at all. But you probably wont pass emissions. a tune will help you pass as well

What I do is I run an ORY but after the Y I have a Cat that I put in for inspection and take off for the other 364 days of the year. Since your a '97 which is OBD2 that would work just get the rear O2's deleted in tuning and when they look under your car they will see a cat after the Y then u pass.

I just bought a Magnaflow 3in Hi-Flow and stick it after the Y its best if you can have it flanged or something so it only takes a couple minutes.

Basically the Cat would go right after the Y-Pipe. The hard part is connecting the two, depending on the diameter of the cat and y-pipe they may or may not slip-fit so modifications would need to be done. But after you install the cat after the Y-Pipe you cut down the Intermediate Pipe of the Catback to match up to the Cat. Its very simple but kinda complex unless you think it through thoroughly because everything has to be done right. I would have an exhaust shop weld a Flange after the Y-Pipe and a Flange however many inches down the Intermediate Pipe with a Flange on each side of the Cat so you can bolt the cat up or down whenever you want to.
^^^The Cat would go right after the Y as you see here on my old Pacesetter set-up
^^^The connections you see from my LT's to my Y-Pipe are Flanges that are just bolted up so all you do is unbolt them and BAM its off so if you had the Cat flanged, you can run no cat or cat in just 5 minutes.

so thats a good idea if i want to move the location of the cat and have the option to go catless. but i think the catless sound would be too aggressive for daily driving.
is there anyway to put in the pacesetters and ory without moving the cats around. im not switching to a catback system, atleast not any time soon.

I'm putting cats back on mine, with the air/egr hooked up and cats it should pass, long tubes don't hurt emissions by them selves, unless your in California and need a CARB number which none of us do seeing as we dont live in California the car will pas. Its not running air/egr or cats that makes the car not pass, not the long tubes it self, they by them selves have no effect on emissions. For example you could have manifolds, block the air/egr off and then run a straight pipe and the car would fail just the same as acar with LTs, no air/egr or cats. I'm doing two high flow cats after each collector. Ideally best situation would be to have two Y pipes to run. Or a set up like FLPs where they are V clamped in or lastly a set up where the cats are flanged in to the Y pipe. The set up I'm going for with the twin high flow cats we have gotten cars with stroker motors and fairly aggressive cam shafts to pass once tuned correctly.
i really just want to put longtube headers on the car. i dont want want to change the rest of the exhaust if i dont have to. is it possible to do that without changing everything? like cat location etc?

Y is a given, has to change no way around it short of running open headers or bullets. Both are extremely loud and not even a viable choice for any one who lives near civilization. On a 96+ cat back the cat back should not even be a issue, on a 93-95 the only thing I could see being a problem is the S pipe that connects to the old cat.

yeah, but what about after the y-pipe? does it just bolt right up? (erm flange/weld right up) i know i have two cats but i dont know where they are. i want to try to keep them for sound/emissions.

Bored and read this thread. I have to say that flanged Cat idea is brilliant lol That's at least as clever as cutting the casing off the cat and welding it around a straight pipe. Hell it might even be better haha
I'm thinking of an ORY since there's no emissions here. I don't have access to a welder though
