Borla CrateMuffler for Chevrolet Small Block High Output 350/383/406 CID S-Type. (400840)

BORLA's CrateMuffler is the world's first muffler purpose-built to optimize the sound & power of crate and custom built motors. The mufflers are directional. The outlet can be identified by the mounting bracket welded to the endcap. The directional design provides custom sound, tuned for each engine family and will dramatically reduce, or eliminate drone on specified applications. Built from premium T-304 stainless steel, superior to T-400 series (such as 409), to give you the absolute best in performance and durability. Precision computer-controlled CNC manufacturing ensures an accurate fit and best of all, BORLA stands behind every CrateMuffler with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

You get what you pay for
Size: 10-11, Color: Cable Knit Black
Comfy but cheaply made. I bought these for the price and expected them to be not the best quality but they are even less than I expected. Please also note that they run small. I got a 10-11 since I wear 11 shoe and Amazon recommended this size. I think a size larger would have been better. Not worth returning though. I’ll just wear them this winter if they last that long and get a better brand next time.

Stains easily. Tight for men's size 11 feet
Flavor Name: XL silicone socks 2 pairs, Flavor Name: XL silicone socks 2 pairs
Husband wore dark cotton socks over these gel foot covers overnight and the covers picked up color from the socks. Tried hand washing, even dabbing with a bleach soaked paper towel, but the stains remained. The covers are a bit tight for men's size 11. Edit: After a few more hand washings the stains began to fade. However one tore around the leg opening when taking it off.

Worthless. Tore on first use.
Flavor Name: XL silicone socks 2 pairs
The first time I put these on my feet, the whole toe broke right through. They were a proper fit and my feet are well pedicured. Just very poor quality. I don’t recommend.
