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 ad-on to my kitchen
Color: Gray, Color: Gray
Way better than my old rusty little basket. This one’s sturdy, doesn’t slide around, and actually fits everything like sprays, sponges, brushes. Love the towel bar too. Simple and works great.

Handy, plenty of space. Diverts excess water to sink. Needs a tweak to keep the cloth hook in place.
Color: Gray
Since it has a metal basket instead of a solid base, it much less messier, which I like. Like that it has a hook for a wash cloth, but that was constantly coming off with the cloth until I used some sticky paddy to help keep it in place. Would probably have returned ii if the time to do a return had been longer. I do like that it has a slope to divert the water into the sink instead of the countertop.

Sink Caddy
Color: Gray
It looks good on back of sink but would be more efficient if it were 1/2 an inch deeper. As it is, it doesn't have enough stability and tends to move about, therefore excess water may not run in sink as front edge doesn't pass over sink edge.
