DEVMO 2pcs XL Size Aluminum Alloy Universal Turbo Sound Exhaust Muffler Pipe Whistle Car Roar Maker Red

This product is decently made. The thing is, it only works on certain vehicles. The noise you get from it varies between exhaust types but most of the time, you cannot hear it. If you can, it just sounds like an annoying whistle sound at the same pitch while driving. The problem is, that it does not cover the whole diameter of the exhaust. ***But I think if you got a bigger size that would cover the diameter of the exhaust, it would work a lot better.***

No silve para nada

Not as load as the video makes you think they are

It’s pretty easy to install but it makes no difference in sound at all. Not worth to even try.

I thought it was great ut fit in my car maybe not the way it was intended and one thing I thought was misleading is that it’s more like a whistle unless you are on the highway at high speeds then it sounds awesome but when you are going slow it’s just a high pitch whistle some people might get annoyed

Mounted these XL Turbo Whistlers on my twin turbo BMW 535i and they do not make any kind of noise whatsoever and I have been a mechanic for 30 years and have mounted these to stay on and not fall off, and the shame of it all was the waste of my tyme, because now I have to take them out because they don't make any kind of noise at all! Why do people sell junk that supposedly works and supposedly makes some kind of noise, which these did not, and i mounted these on a stock exhaust system! These XL turbo noise whistlers never made any kind of noise,it doesnt do anything!I hate returning anything!

Doesn't work at allNo sound .But my kids are having fun now using it with mouth as a whistle..

Doesn’t make much noise and doesn’t hold on too well
