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.

Good Compact Design
Color: Black
Attractive design and space to store the dish brush and or sponge. My only criticism is that the pump spout is quite narrow so the liquid soap skims over and not that much is released with each pump.

Bad product, cannot recommend
Color: Black
This product didn't work well at all. The material gets smudged and dirty extremely easily and it's impossible to get it clean. It's also very heavy, but not in a good way. The pump shoots out dish soap very far and makes a mess on the counter. Even when I hold the sponge or brush right by the pump, the dish soap still went all over the place. The pockets for brush and sponge did not work well either. Even the taller back pocket was way too short to hold a normal size dish brush. I ended up throwing the item in the trash.

Went from five stars to three.
Color: White Marble Look, Color: White Marble Look
I was thrilled with this dispenser & sponge holder for the first month or two then soap started oozing out of the top. (See photo) I didn’t change types of soap but am trying different things now to see if it helps. It’s a great fit in my kitchen, holds the items I need, is sturdy, looks classy and clean but I’m not sure if I’ll get used to the blue ring of soap oozing out. I’ve been using this for 2.5 months at time of review.
