Eliminates weak points in the factory design that can lead to boost leaks or complete failures in hard working and high performance applications. - - Kit replaces the restricted 2-piece, resonator equipped, 2.5 in. diameter driver (Hot) side intercooler pipe and leak-prone 2-piece plastic / rubber passenger (Cold) side pipe with WCFab's heavy duty 3 in. diameter 1-piece Driver (Hot) Side and 3.5 in. diameter Passenger (Cold) Side L5P Intercooler Pipes.

Mediocre mens shirt
Material feels great, however the product doesn’t hold up to laundry when following the instructions. The process makes it acceptable, you can get maybe 6 wears out of it before it makes a great Buffy cloth for waxing car

Good quality! Very fair price.
Color: White, Size: X-Large
Great quality!!! Good pricing as well. Normally buy LL Bean, these are half the price and will likely not shrink!!! Typically wear them under another sweater or shirt. Size fit good with exception of sleeves' which are at least 2 inches longer then most of my XL shirts...just rolled them over!!! Good look for sure!

Comfy Turtle Neck
Color: Light Blue, Size: Large
Very nice quality, soft and plush. Very tight turtle neck that holds its place without sagging. The sleeves are long enough to cover the wrist bone.
