ORY/Catted Y

[Mike0202]

I was thinking of ditching my highflow cats but now I cant decide if its worth it. Is it just me or is there really not that much of a difference? I think the ORY is more raspy, thus making it a bit louder but thats about it. Maybe add 2-3 more hp?

More raspy, yes.

More flow than high flow, yup. So it should add more HP, how much depends on your setup. Maybe 10HP at the most? But no one will know (Unless they have the same setup).

For a $200 mod, $/HP gain, at least over stock, it's a nice addition when doing headers and catback.

With a tune and the additon of a ORY, you should be running a few more HP,
Just remeber, an inch is a mile, lol.

Just remember an inch is a mile, lol.

Dont do it!

even hi flow cats are a restriction. a y pipe is well worth it imo

It's really a matter of whether you have to deal with emissions or not.

I don't run cats, prefer the off road Y. Not because I was looking for the HP gain (very minimal on a bolt on car) but I want to eliminate anything that is a costly maintainance item.
Quite frankly, cats of any kind are expensive and don't last forever. Ditto for the 02 sensors required to keep tabs on them. So that stuff goes by by. Less crap to worry about. I prefer to simplify the car as much as possible.

Yes they are a restriction not to mention a source of extreme heat. Like mentioned, probably more of a restriction on an all out effort HP build.
I don't worry about rasp as it's called on here, there are other ways to deal with that.

I have one of the cats plugging now. Or the O2 behind it going bad. Not sure, just had enough.
Long tubes and a ORY will solve the problem in the spring.
It will be nice to eliminate those expenses for good.
The exhaust on the pre cat cars smells ok and with the right pipes they are not that loud.
I would go for the ORY.

That's funny you mentioned the smell. I never gave that a second thought. I've been around carbed, gas guzzling, obnoxious and rambunctious muscle cars all my life, so it all smells good to me

i never thought of it until some friends pointed out the smell of my old cars to me. I always liked the smell of exhaust. kind of like the smell of the 60s interiors too.

I ran my ORY with my lt's and catback and added some small 3" bullet cats that came off a vette and notice no power difference I just used them to cut down the smell and the sound at idle and low rpm since Everytime I pulled next to a cop I would get followed. The HP gain wouldn't be anything you would feel since I can't see any difference except sound and exhaust odor.
