I have a loud car already, the M3 is my daily car so I don't want it too loud, just want to brighten up the tone, and definitely no drone. I already bought the Evolve tune, haven't decided weather to get the HFC or test pipe yet. HFC are expensive but it should sound just right. Test pipe might be smelly and might be a bit too loud for me. Does anyone know how much louder is the test pipe comparing to HFC?
