hi guys well. i added a magnaflow muffler to my car which i made a soundclip of. my setup is 2.5 no cat with the 14815 from magnaflow, my question is should i add a high flow converter from magnaflow as well?
sound clip : YouTube - BMW E30 325I
cat converter :
whats the difer from a high flow to an OEM cat?
will the high flow sound a bit louder than the oem or it will just quite the car?
