## Description

Blow Off Valve Trumpet, Whistling, Aluminum, Black Anodized, Go Fast Bits Blow Off Valves, Each

Review: Unique sound! Great customer service! - The seller reached out immediately to let me know the product is black, not silver as pictured. Black was actually my preferred color so that worked out perfectly. The product has a cool unique sound that sets it apart from the standard "whoosh" I call it "lightsaber" noises. Still needs at least 10psi (~90% vented to atmosphere). Easy install on my Respons bpv. 05 Outback XT 18G w/ Verticooler.
Review: Really loud whistle - It certainly whistles! I actually grew to dislike it because of how aggressive the whistle is. It sounds like a falcon in my engine bay. That's no fault of the product tho, it's still fantastic quality

## Features

- Suits all valves exc DV+, use for low boost applications)
