Z3 1.8 Exhaust....

[peterzoom]

Hi everyone, just purchased a z3 1.8 1998 model. Looking to change the exhaust for somthing that will sound a bit throatier without resorting to Saxo/Nova type drainpipe levels.
Happy to consider a full system as well as rear box only.
Have any of you got any advice on what might be best?
