I am but it has to have the following very specific specifications:

a) must improve performance - not interested in a looks only, must perform and perform well
b) ZERO interior resonance - absolute deal breaker with me if it causes interior resonance I will not be buying it. I've had too many other exhausts on previous cars do this and it ruins a ride
c) must be civil so no change in interior noise unless under WOT, or over 5000 rpms
