HI Jeff--
Over the years I tested about six different aftermarket exhausts and based on sound, lack of resonance and performance I went with Corsa for most of those years right up until I went back to the stock cat back exhaust with cutouts. On the 93 we had headers with cats mostly plus the Corsa, and on the 95 headers and no cats with Corsa and Stock. My conclusion is that with a high flow aftermarket exhaust system, the catalytic converters soften the sound and make it a more pleasant driving experience. I always said it seemed to be about a 20% improvement in the sound, whatever that means
. I believe they only cost about 2-4 HP and do make the exhaust smell better and help the environment. With no cats there was definitely a noticeable smell on startup, kind of like we used to get in the 60s and 70s. But not so bad that I wanted to return to having cats in the system on the 95. But it was quite loud with the Headers, no cats and the Corsa, an issue resolved with the stock systems and cutouts. When I was younger I think I liked the Corsa with cats the best, but as I ease into old age, I really liked the stock system with cutouts. Quiet when I wanted it (but still a decent sound), a nice rumble with the cutouts partly open, and a straight thru exhaust with them fully open for racing and scaring dogs and small children. But as they say, your mileage may vary.--Bob
