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.

Moisturizing
Easy to apply, does not feel greasy. Used on legs after shaving. Did not clog pores. Legs felt smooth and moisturized

Got a rash from it
Color: Green, Size: 2 Fl Oz (Pack of 1)
I'm in that percentage of women who have chin hair, unfortunately. I shave almost every day so I bought this thinking maybe it would help stretch it out a few days. I used it twice and broke out in a rash (just on the chin/neck area). I was sitting at work and subtley scratched my chin area. Thought nothing of it. Then I scratched a little more. Until I realized something wasn't right. By the time I got home I could see the red. My skin can sometimes be sensitive to new cleansers/creams/oils. It may work for some, but it didn't work for me. On a positive note, it's odorless, lol.

Great after shave product for smooth skin
Color: Green, Size: 2 Fl Oz (Pack of 1)
Not only does it help slow hair regrowth, it helps with razor burn too!

PLEASE MAKE A BIGGER SIZE, NEVER STOP MAKING THIS ‼️
I purchased this a few months ago back in November 2025 because of all the TikTok hype. It's now June 2026, and even though it's only 50ml, it lasts SO long. A little goes a very long way, and I still haven't finished it yet!! I originally bought this to use after waxing my underarms because I'd always get painful bumps, irritation, itching, and overall discomfort. I'd only apply it at night, and by the next day the bumps and irritation had gone down significantly! Whenever I get bumps, irritation, or discomfort, I use it for about 3 days to a week and it works so fast 😍 I really wish they sold a bigger size because the reviews are not lying💯...this thing works wondersss. It's worth every single dollar. It's also pretty good at targeting ingrown hairs too. Like omg, it's basically a painkiller in a bottle 😂 It has saved the day so many times & I've used this quite a lot, lol.

Charming Roll-On Power
I've had a difficult time with shaving with sensitive skin. I can use multiple different types of razors, lotions and creams. It doesn't always work well for me. So I saw this mentioned on TikTok and I thought I would give it a go. I'm impressed by how good it calms any irritation or itchiness I may have. It applies on cool and and it's easy to use. It carries no scent. It's a small roll-on and lightweight. It's soothing and moisturizing to the irritated skin. Works like a charm. Would recommend!
