  ℹ️ DESCRIPTION

The exhaust manifolds found in the 1999-2003 Ford F150 and F250 were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 Long Tube off-road headers are designed to allow the exhaust gasses to flow more freely from each 4 cylinder bank and combine more efficiently. Tubing has been optimized for the 5.4L(330ci) engine. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.

runs a bit small
Color: Ocean Blue, Size: Large
lightweight, comfortable. However, I needed to return and by one size larger. I wanted it it for a comfy - nighttime- like PJ's kind of fit.

Comfortable and Pretty
Color: Claret, Size: Small
Nice cut for a t-shirt and I love the color. Bought for a trip to Asia, it's soft and comfy. It dried overnight in 80% humidity after washing. I was looking for natural fibers that is quick drying.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.
