Default ORY or keep the factory cats with Corsa?
I have a corsa catback on my 2002 ss........I do not want to put headers on the car. I just want to get a little better sound, and I figured the stock cats and y pipe was a little restrictive. How much power gain can be expected from ditching the cats? Also, will the Corsa sound better with or without cats? I do not want a raspy sound at all. I really like the way the car sounds now, just hope to get a little better sound at an idle.

minimal power to be gained from removing the cats...3-5hp at most.

i'd be willing to bet the sound at idle will be better, but WOT will be raspy.

you could always throw a 24" bullet muffler just behind the Ypipe to cut down rasp.

biggest problem with orp is the clearance. i had a helll of a time with my bassani...and i noticed no gain in power.

headers or don't bother with the cats/ypipe

Sorry, but being quite at idle and light load is one of the main features of the Corsa cat-back. Having said that I liked the sound of my Corsa the best before the cam but after the headers and catted Y.

Keep that cats for sure...main reason being that car will smell like gas without them.
