depends on your exhaust.
if you have a loud exhaust, you will notice a difference, if you have a quiet exhaust you won't notice too much of a difference, but you will notice a difference.

personally I prefer cats, yes they rob you of some HP, but IMO the exhaust sounds soooooo much better. Even cutouts sound a lot better with cats.

you will definetly hear a difference but it will just sound alot better still tame volume wise after i took out my cats its night and day on the sound not to raspy either and would never go back to cats . by the way my setup is very close to a gmmg when compared to a few cars that had the gmmg

what exhaust are you running? i guess its all opinions on the sound, how hard is it to remove cats and make the jethot y an orp? i think before i get it all welded ill try both ways.

its a custom setup with swwet thunder mufflers similar to gmmgs setup but being custom bent it doest flow that great. sounds insane with the cut out open though one of these days ill fix it as for the cats you can alwasy try it but ill tell ya i wish i just got a ory in the first place mines all welded now anyway all the lil pieces can be a pain to line up and the race pipes fit a little tight on mine

so yours is welded so you cant put the cats back on unless you cut the y pipe?

You could have a custom Y pipe made, I don't think it would be too expensive either. Order the headers, install them and go off to the muffler shop and let them bend you a Y pipe and install any cat of your choice. Carsounds are very good, and very cheap
Also if your willing to spend a little extra cash, the muffler shop can setup the cats so they can be easily interchangeable for straight pipes. My passenger side cat is easily removable, basically 3 bolts and it slides right out, my driver side cat though is welded in place because they came with clamps and the clamps didn't work too well

00 Formula, heads and 224 cam, jethot long tubes and magnaflow. love the sound with jethot y-pipe with cats and still dynoed same numbers compared to off road pipe cars. Interesting about them clogging

the problem with having a shop around here make me a y pipe is they dont mandrel bend pipe, and i sure as hell dont want a non mandrel y pipe over a mandrel y pipe. jethot should design their sh** better .
