Installed one of these for fun and forgot about it. Now 2 years later, when I changed my exhaust a few days ago, I got reminded that I had that thing still in there, total junk and doesn't work at all, but it was not to big of a financial loss so nvm.
So many people don’t know how to use these lol If you have a big diameter pipe you need to fit a funnel on the end of the whistle. They’re actually very loud ✌️✌️
It works best with a Turbo engine I have a Turbo engine in a BMW 228i two pipe convertible it sounds awesome like starting up an all sports car like on Rocky III…
