5 Top Rated Questions

Does the diffuser itself come in matte? Or is the whole thing just primed white?

  • The GT500/CS Rear Bumper Cover w/ Diffuser will come as completely unprepped and unpainted polyurethane. This will require the diffuser to be painted matte black in order to achieve this finish.

Helpful (0)

Does the bottom part come off for easier painting?

  • The GT500/CS Rear Bumper Cover w/ Diffuser comes molded together in one piece. You cannot remove the diffuser to paint that area separately.

Helpful (0)

Only comes unpainted?

  • Unfortunately the GT500/CS Rear Bumper Cover w/ Diffuser will only come unfinished.

Cutting the exhaust holes to fit quad tip (dual on both sides) exhaust? I have an 07 GT and it currently has a Saleen H-Series rear bumper and deck lid panel, and dual tip exhaust on both side. Personally I'm not a fan of the Saleen bumper and would like this one but I would like to keep the exhaust the way it is. Thanks in advance

  • The GT500/CS Rear Bumper Cover w/ Diffuser - Unpainted (05-09 All) can be modified at your own discretion to fit quad tips if needed.

v6 I have a v6 mustang with the stock exhaust, but I will not be able to install dual exhaust yet, will this bumper fit my v6 on stock exhaust or shoul I wait till I get dual?

  • This bumper will fit on your car with the stock exhaust, however, it just won't look very good. There will be an empty exhaust cutout on the driver side and the tip that will be coming out of the other cutout is much smaller than the cutout itself. But if you want to do it, you can. I would recommend getting the dual exhaust before purchasing this rear bumper. It would actually be best to have both the exhaust and bumper installed at the same time, that way you or whoever is installing them can make sure the tips fit perfectly with the bumper. If you can't install them at the same time, then I would get the exhaust done first. Again, that is just my opinion. If you want to install the bumper first then you shouldn't have any fitment problems.

    Not happy

    Not happy with the run around I get with American Muscle.. Received the first Gt500/CS bumper cover damaged they had me destroy it.. Received the 2nd one damaged refused delivery.. Been 3 weeks now and I get the run around and not a honest answer on what's going on.. Last week 3/20/2018 I was told this matter was taken care of and my new bumper cover will be sent out this week... I called 3/23/18 stating I still haven't received a e-mail confirming it 3/27/18.. I was told you will get a e-mail today 3/23/18 or 3/26/18 on shipment.. I still haven't received it...

    Much better

    This is a subtle change to my mustang but I love it. It looks much better than the original bumper. Installation was pretty easy and the quality is going too. I wish it was a little bit better but overall this is a good product.

    Nice Looking Bumper

    Great looking bumper, but went through some trouble getting it. Came in over two months after ordering it, box was delivered crushed. Sent it back and waited another three months to get it. I went myself to the UPS freight center to pick it up. No damage. Drove it straight to Ford. They looked at it and showed me all the flaws that needed to be fixed before painting. It did need a lot of work. It really needs to be professionally done. Next day I drove my car back and they installed it. The tab on the bottom for support was not connected because it lined up with nothing. When I get the chance, I'll drill a hole in the frame to connect the tab to it. The bottom of the bumper is textured so it made it hard to paint the flat black I wanted so I went with gloss. Looks ok. Cost an extra $450 to paint and install. Once the bumper was installed I was able to have my Pypes Dual Exhaust installed and then hook up my Bama Tuner. I've had those parts in my garage since October 2016 waiting for the bumper. The Mustang looks good and sounds good now.

    I got a great deal on a rear bumper cover. I was worried about fit and finish until the body man told me it was actually a Ford part. What a deal!

    Awesome Aggressive Style

    I converted my Pony Package V6 to a dual exhaust but didn't want to go with just the stock dual exhaust bumper. This one gave me the aggressive look I wanted to match the aggressive new sound of my car. The combination is a real head turner. The only issue I had with the bumper is that it's not a completely perfect fit on the sides. It sticks out very slightly as if it needs to be popped into place. I had it professionally painted and installed so I may have it adjusted a little to get a tighter fit. I'm kind of a perfectionist though and you can't really tell unless you take a close look.

    Looks great!

    This is bumper has a great look to it with the diffuser. I had a body shop paint it gt/cs style where there lower half is painted where as the gt500 is unpainted. The body shop had a little trouble trying to match my paint p3(Windveil blue) but in the end got it pretty close. The fit of the bumper is very close to perfect, good enough for me.

    GT500/CS Rear Bumper

    Had the bumper painted and installed by the body shop while repairing some minor 1/4 panel damage. The look is a fantastic upgrade to the stock Bullitt unit, though on the driver's side it would not fit flush with the body panel and tends to pop out a little out at highway speeds. You can pop it back in with your hand though. The shop suggested heat but I declined. Sure it's a minor fix though.

    Rear bumper with diffuser

    As the body shop said where work was done, "this is better then original bumper". The new bumper fits perfectly and it changes the entire back end of my Mustang for the better. Well worth the price and as usual great service from AM.

    Quality Product

    The clear coat on the rear bumper cover of my 05 GT was peeling off so I thought I would replace it with a new one. I like the look of the diffuser on the California Special. After receiving it my painter had me look at it. It's a good quality product; however, the bottom 3" has a texture to it and he was afraid I wouldn't like it painted. He wanted another $150 to sand and primer it smooth to paint. I opted not to Have it smoothed out but to paint over it. I'm pleased with the result but it's not perfect. Install cost included painting.

    Very High Quality

    Being a genuine Ford product, this bumper cover looked fantastic right out of the box. It required minimal prep before paint and fit my 2006 GT perfectly. I absolutely recommend this product to anyone who wants a more aggressive bumper than stock.

    When the product was received, the shop told me it was not damaged in any way and it fitted exceptionally well. Considering it was an OE fit, I did not expect anything less! It looks great on any Mustang!

    Looks great, not perfect fit

    The bumper cover looks great, especially with the diffuser on the bottom. The fit, however, isn't exactly perfect. This is especially true with certain exhaust systems lining up. So long as your not looking for factory perfect fit, it is a good buy.

    Oem Bumper is a perfect upgrade to this year mustang

    Package came with no damage, the bumper was perfect and even included the factory mounting bar that runs from driver to passenger side which most aftermarket bumpers do not. If you want a great upgrade to your mustang and want OEM quality fit and finish this is the bumper that you want to purchase.
