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.

Very nice bracelet organizer
Color: Black, Size: 2 Rolls
This is a great jewelry box for holding bracelets and watches. Easy to open and holders are easy to remove and replace. I especially like the see-thru lid: keeps dust off bracelets and makes it easy to see what's in box.

Would buy again
Color: Black, Size: 2 Rolls
I love it but wish the tubes the bracelets slide onto were a bit smaller. It’s difficult to fit cuffs on without having to bend them and I don’t even have small wrists. Very pretty and fits a lot of cuffs and bracelets.

Love it!
Color: White, Size: 2 Rolls
A very nice bracelet holder. It's much better than I anticipated. It holds everything perfectly. There is enough room on the bottom to store a lot of different things. The bracelet hold there feels sturdy, and I love the color. I like how I can look at the bracelet through the window.

Impressed. This is a nice case. You can slip the bracelets on without any fuss. While I haven’t finished filling this one, I’m already considering a second case for watches and ankle bracelets. It’s convenient to see your items rather than digging for them. Nothing gets tangled either. There’s room for storing additional items below the two display rods.
