Depends if BHP is your only aim not all 100 cell cats are that good some you have to get the car really really hot to get them to pass some still won't pass so you will have to buy a quality one ( cases on the forum )
I went for the 034 cat which is 200 cell and has no emission problems. For the sake of living in a city with VOSA and Police inspectors setting up random checks in the city centre virtually weekly I'd had enough of playing cat and mouse
