Hmmm, if you are asking whether the Corsa systems will work with catalytic converters, the answer is yes. They are 'cat back' systems that bolt right on to the end of the cat and replace the stock mufflers and pipes.

I was actually wondering whether should i remove the cat and install the corsa exhaust or should i keep the cat and install the corsa?? What's the difference with or without the cat when i install the corsa exhaust? Thanks!!

Phil, Removing the cats or replacing with hi-flo cats will increase the noise level quite a bit and also lead to popping and blubbing on over-run, but it makes the sills run a lot cooler. I went with the hi-flo cats to avoid the anti social exhaust smell but ended up with the anti social sound level instead
