The Sound

Here at Kline, we felt that the Factory exhaust for the 458 did not reflect the true beauty of this stunning supercar, or reach the full sonic potential of the 4.5 liter V8 Starting at the drawing board, the first aspect to be upgraded, replacing the 600cpsi catalysts for high performance 100cpsi race catalysts, thus reducing the gas drag coefficient, and improving scavenge, and ultimately torque response and peak power figures. Replacing the heavy, cumbersome, built down to a cost factory silencers, for our harmonically tuned silencers, we were able to enrich both bass and treble frequencies, as well as significantly reducing weight. The final, and perhaps one of the most important design features, unique to Kline. Our trademark tight radius laminar flow x pipe. The resulting sound is unbelievably smooth under light driving conditions, and a howling raucous high pitched incendiary vocal when you need it. Under low revs (valve closure) the gases are allowed to pass through a chamber, and an acoustic ceramic filled silencer, with the cross sections tuned toward reaching optimum gas velocity for achieving maximum torque. under hard load and high revs, the valves open for optimum power.

Soft and comfortable, NOT firm.
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
Overall, these are comfortable pillows for the price, especially if you prefer something soft rather than firm. The pillows arrived vacuum sealed, which is pretty standard. Once opened, they fluffed up well after some time and looked full enough to use. Right away, they felt soft and plush, and sleeping on them was comfortable from the first night. In terms of comfort and support, these pillows are definitely on the softer side. They work well for side and back sleeping if you like a pillow that you can sink into a bit. They’re not firm or dense, but they’re still cozy and gentle on the neck and head. After a few days of use, I did notice that the pillows started to look a little lumpy and uneven. The filling tends to shift, so they don’t hold their shape perfectly and need regular fluffing. That said, even when they look a bit misshapen, they’re still soft and comfortable to sleep on. If you’re someone who needs strong neck support or prefers a firm hotel-style pillow, these may feel too soft. However, if comfort and plushness are your priority, they do the job well. For the price, I think they’re a good value. They’re not luxury pillows, but they’re comfortable, decent quality, and perfectly fine for everyday use or a guest bed.

Would buy again
Color: White, Size: Standard (Pack of 2)
This is a good pillow if you like them firm and thin. I let them sit out for 2 days (per instructions). After having them a week, they've perked up and became more full. I guess they just need time after being in the air. They are softer now but your head doesn't sink thru it. They are actually nice and soft to the touch as well.

On the thin side....
Color: White, Size: King (Pack of 2)
These are described as "high loft" and "supportive", but they are fairly thin/flat and very soft.

Great Support; not too Soft.
Color: White, Size: Standard (Pack of 2)
These are extremely comfortable pillows. I bought them for my every-night use, and they have not disappointed me. They provide great support for one’s head. They mold around one’s neck foot just turn perfect amount of support without being extremely soft. They hold their original manufactured shape easily.
