Hello, I have a factory standard f30 318d sport auto, I have had it re-mapped and I really want to get a sporty sounding exhaust on it, any recomandations ? I've been told it's difficult because of the DPF filter, is there any way of getting a nice sounding exhaust that doesn't affect the dpf? I've had a quote from mij exhausts but some of the reviews say about engine warning lights coming on because of sensors in the exhaust ?
