This Flowmaster American Thunder® cat-back exhaust system for the 2004-2008 Ford F-150 and Lincoln Mark LT trucks with the 4.6L or 5.4L engines, is perfect for the person looking for a deep aggressive exterior sound with a moderate interior tone, and with all of the performance benefits that you would expect from Flowmaster®.

The tailpipes exit either behind the rear wheels, which is ideal for towing, or straight out the back under the rear bumper for a muscular look. The system is finished off with a pair of large 3.00-inch polished stainless steel tips. The exhaust system is covered by our Lifetime Limited Warranty and includes all necessary parts and hardware for an easy installation you can do at home. For those who prefer all aluminized steel construction with a 3-year Limited Warranty, check out exhaust system #17417. Note: Fits 2/4 wheel drive models all wheelbases.

    Decent Light Bars, But More Options in the App
    Color: Black
    The Govee RGBIC Light Bars are pretty decent overall. The lights are bright and add a nice atmosphere behind the TV. The 15-inch bars fit well for a TV setup in the 45–70 inch range, and the different placement options make it easy to set them up the way you want. They do have some regular lighting settings you can use without connecting to the app, which is convenient if you just want simple colors. Setup is fairly easy and they look clean behind the TV. That said, I do wish there were more options available without having to rely on the app. The basic settings work fine, but it would be nice to have a few more built-in modes. Overall, they’re solid lights that look good and work well, especially if you like adding ambient lighting to your TV area.

    Cannot recommend this brand enough!!
    Color: Black
    Although govee is a bit more expensive the price is worth it. This is the second pair of lights I now own by this brand and seriously they are unmatched! The lighting is phenominal while they remain relatively light in weight. While thwy do have a built in remote on them they also have a govee app which is extremely accessible. It allows you to pick from a RGB wheel, the brightness, and even different flow modes. The light is broken up into segments internally allowing for maximum customization.

    Quality, Easy to install, Infinite color and setting options
    Color: Black
    Yet again, Govee does not disappoint. Super easy setup (especially if you already have the app installed) and just the right amount of ambiance with seemingly unlimited color options and various still, or dynamic settings. Oh, and all this fir a very readonable price. Big fan here!

    Great not only for TV Backlighting, but shelf lighting too!
    Color: Black, Color: Black
    Right off the bat, these light bars are vibrant, colorful, and have a great variety of different colors and patterns. However, I used them for a little bit of a different purpose than what they were created for... I had previously purchased the TV backlight strips from Govee, and wanted to find lighting for my shelves within the Govee ecosystem. Traditional light strips wouldn't really work unless I spliced them, which I wanted to avoid. Enter these light bars. I bought 2 sets of them, and thanks to the (quite strong) mounting options, was able to mount and angle these lights downwards to create a really cool effect over my displays. I wasn't sure how well it was going to work, but the end results speak for themselves. It looks terrific when used in this role. The cables are very long and manageable too, I was able to run them down the support beams of the shelves with some mounting clips without issue. The only negative comes down to the app itself. It's a bit overwhelming and confusing to use at first, but once you get the basic functions figured out, there's little issue. Still, I feel the user experience could be improved on the app. For example, I had to go in and create my own shortcut function to turn on all my lights at once, then make a separate one to turn them all off at once, as opposed to there being a single master on/off button in the app. It's small things that can make the app tedious to work with. Regardless, I feel that overall Govee continuous to knock it out of the park. The lights are bright, customizable, and add a ton of ambience to the room. I hope Govee continues to expand on their different room lighting options and keep the level of quality they are putting out now.
