Overview:

Flowmaster introduces our Flow FX Extreme stainless steel cat-back exhaust system for the 2007-2021 Toyota Tundra with the 4.7 or 5.7-liter engine. This system uses a Flow FX series muffler for an aggressive to moderate sound level and increased performance. 3.00-inch mandrel bent 409 stainless steel tubing allows for maximum exhaust flow and durability. The system has a turndown style, dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps improve ground clearance and departure angle when you are driving in more extreme off-road situations. This system produced max dyno gains of 5 hp and 6 lb-ft of torque at the rear wheels. All of the necessary hardware is included, and factory-mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty

    Well built and removes cleanly.
    Color: Dark Black, Size: 1 Pack
    Seems to be very solid and it was a little bit tricky to get it located on the vent blade properly, though that might just be due to the vents shape in my Highlander. I really like that it can be easily moved from one vehicle to another if needed without leaving adhesive residue like my last mount did. The only concern I have is whether the vent blade will support the weight long term. Time will tell I guess. EDIT: This fits all of the vents on my 2011 Highlander great. On my 2022 Highlander it will only attach to the center vents and then just barely hooks on after angling the vent blades enough for the hooks to grab. Even then the mount only makes contact at the very top and bottom of the vent opening. It works, but I wouldn't recommend it as ideal.

    Best phone holder I have ever purchased!
    Color: Dark Black, Size: 1 Pack
    Hands down the best phone holder I have ever purchased. The ones that stick to the windshield always end up coming loose. This attached to your vent and is super sturdy. Very easy to install and uninstall without making a mess on your window.

    Well worth it. Great product.

    For the inexpensive price it’s worth its weight in gold. I admittedly probably didn’t work on it as long or as hard as I should have, but I still had great results. *** One warning: when it says to “tape up and cover your paint around it” do it! I figured I would just be careful but no I was wrong. It will REALLY damage your paint, so make sure you don’t get any on it. YES- This is the sanding discs too! They have chemicals on them, they are not regular discs. If you do get on paint, clean immediately! My only regret with this project and my fault, not theirs. My headlights went from dingy yellow, to much brighter and definitely more clear. Love the results. Very happy with the purchase.

    Great for the price

    Worked great at clearing my headlights and at a great price, I had used a different headlight kit maybe 5-6 months before and it did not perform as good as this kit did, maybe it was a user error with the previous kit but this one cleared it easily and was very easy to do and had a nice clear shine.
