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 a patented, award and race winning multicore high flow design just like the standard XR-1(r) muffler for maximum power. This muffler is recommended for Dragsters, Altereds, and Roadsters. 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 sink caddy
Color: A-silver, Color: A-silver
This sink caddy is great, has slots for the necessary things, sticks perfect... Has 2 different options and I chose the one with the suction cups. Almost a week, still holding perfectly. I only have 1 thing I would change, that is the end of it that I just realized from the picture, holds the sink stopper. I have a garbage disposal so don't need that and it makes it a little too long. Other than that, perfect and it still works well and sticks on perfectly.

Leans forward with suction cups
Color: A-silver, Color: A-silver
I really like all of the spaces and the metal is good quality. However it leans forward when using the suction cups. I haven’t had that issue with other holders.
