Hi- flow cat question

[nofearracer]

I am thinking about putting a set of hi-flow cats on my car to bring down the side sil temperature, and help the sound a bit(the car already has corsa exhaust). I was wondering if doing so would cause any warranty problems, and what kind of sound change to expect.
