      Review & Installation Video

      Hey everyone, Justin here with, checking out these really cool billet grilles for your 99-04 V6 and GT Mustang. Billet grilles are a great way to drastically alter the front end of any ride and now with this grille you can give your New Edge Mustang a face lift while still maintaining your Pony emblem. Each grille is constructed of 100% billet aluminum so you know they’re built to last, and they’re available in two different finishes. You have the polished aluminum finish here, we also have a mirror black finish as well. Now each grille does come with all necessary hardware needed for installation, and should take about 30 minutes using standard hand tools. Now of course the upper grille looks great on its own but if you want to complete the look you might want to check out the lower grille as well, you’ll save yourself a few bucks if you purchase both at the same time. So if you like the look of billet grilles but you’re not ready to ditch your classic pony emblem, then this is the look for you.

        Think Twice

        American Muscle won't stand behind the product so ask your self if you want chrome that peels after being on the car for three months,

        3 2003 GT - Michael

        Expected better quality

        Plastic is of good quality visually, durability and flexible. Wasn't a flush fit from end to end and the curvature was short so it didn't perfectly match the curvature of the bottom of bumper like it shuld, that's like a hood that is one foot to short, it shuld match as if it is factory. The hardware is improper, bolts shuld be hex head with lock nuts but instead it was phillips bolts with lock nuts making it difficult not to strip out the heads. All in all it looks good but keep in mind that it might not be a flush fit from end to end so adjust accordingly to center the fitting. Trash the phillips bolts that for me became a headache.

        4 2004 GT - MichaelP Installation Time: Afternoon

        Nice paint and polish - good quality.

        Nice look for those that don’t want a grill delete. The main grill could have been about 3/4” wider to fully fill the opening. Fairly easy install over the honeycomb, would be much harder install without the backing. Much better with a scoop grill.

        Bad screws

        I was very happy with the look of the new grill, but i was very dissapointed when it arrived to find out that the screws that came with the product were too small and fell right through the fastening holes. i ended up using black zipties to hold it.

      I could not locate this item in its counterpart, Black finish. I was curious as to where I can find this same grill in black. Also, as a follow up question, assuming I purchase this same grill in black for a 2004 V6, would it be possible to replace just the pony emblem itself?

      • The Modern Billet Black Billet Grille, sku 17080 can be found at the link below: We do not carry a pony emblem in black that works with this grille, however you can paint the existing emblem in your car black to match.
