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

    Weird smell
    Color: White-cooling Basic, Size: Queen(Pack of 2)
    The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.

    helped treat my sore neck
    Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
    This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

    Love them!
    Color: White-cooling Basic, Size: Queen(Pack of 2)
    Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!

    Great pillow, but the cooling effect depends on the cover
    Color: Blue-ice Plus, Size: King(Pack of 2)
    I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation. However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through. That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone. Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.
