Sorry. Hate to give bad reviews, and I never have. But when the product does not work as advertised, a man has to do what a man has to do...Tightened everything once package arrived. Unit came with no set screw and the two pieces of the whistle were loose.Tried it out by simply blowing in it. Worked fine. Tried it on multiple vehicles. Tried a 4, 6 and 8 cylinder. Even 2 cycles. Nothing. Not a sound. I noticed that once I removed it that it would not function even by blowing through it until it cooled down... so heat stops it from working? Seems like a real design flaw on something that you insert into a hot exhaust!!!Super diappointed... sorry, seller....

no sound

When you have a bigger exhaust it doesn't work at all it's meant for just small cars and motorcycles

Lost the whistle inside (not the shell) in 2 weeks.
