This is the HOT set up in drag racing. This patented, award and race-winning vacuum Wave Collector was designed to replace your current open header collector and serves as a power producing merge collector and muffler -- all in a single unit. The technology in this unit results in pulling air through the engine faster, which creates more power. When an exhaust valve opens, an energy wave is created from the expanding combustion gases. When this wave encounters a lower pressure area such as a larger collector pipe or the atmosphere, a reversion wave is reflected back toward the exhaust valve. Borla's Vacuum Wave Collector Muffler ensures this wave's "anti-node" reaches the exhaust valve at the precise time for its lower pressure to help fill the combustion chamber with a fresh charge and to further extract spent gases from the chamber via a vacuum effect. Made with the same patented, award and race winning flow through design as the Standard XR-1(r) Collector/Muffler. This muffler, however, is designed for door car applications where a Standard size Collector/Muffler is too large. This muffler is recommended for Full Chassied Cars. Accepted in NHRA, IHRA, Hot Rod Series, Brackets, Super Chevy, and NSCA. Recommend for high horsepower applications. T-304 Stainless steel will never rust. 100% welded construction for strength. T-304 stainless steel wool for sound control. Best of all, it's made in the USA. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

Great addition to my sink!
Color: Black, Color: Black
This is a great sink organizer. I like a place for everything, and to hang up our dish cloth when done using it. We had a suction cup holder for that purpose but it broke several weeks ago. When this came in I noticed the 'washcloth bar' was just as another reviewer noted....pretty useless, unless you find a way to glue it down, so I chose to just toss that piece. We hang the cloth on the front fork piece, but that is also not secure and kept falling off. The simple solution for me was using some electrical tape to secure it. Not even noticeable and now works beautifully. Love the drainage with the sloped bottom, and having a spot for all the little thing we need handy at the sink. Highly recommend!

Organizes & is inexpensive.
Color: Silver
Keeps items tucked & organized. Waterfall is not high enough off of sink if sink rises above counter more than an inch. Works fine for the price.

Convenient & organization
Color: Black, Color: Black
Size is Perfect for kitchen sink. It allowed for me to organize all the things laying around on the counter near faucet. Very functional and good value compared to others. The only thing that I would have preferred is to have 2 hooks for the Scrub daddy and lose the dishcloth hanger as I tend to to pull cloth and hanger off when I grab to clean or wipe something down.
