Was on streetstyler.com and found a mugen front lip and a mugen half front bumper lip. I was wondering what the differences between the two were. Does the front lip replace the oem? Does the half front bumper lip cover the oem? By the way its a 97 ls 2 door

if you already have a stock lip then it replaces doesn't cover. if you don't then it just adds on to your bumper. i don't know which ones you're talking about so i wouldn't know the difference.

There is only one Mugen front lip.. which is this one

Lips dont get covered by other lips.. they get replaced.

from the pics on streetstyler it looks like it just covers up the oem bumper
