Annoying Auto Exhaust Whistle-Gag Gift

I work at an automotive repair shop. Put this in my bosses tailpipe. He drove past us and we couldn't breath we laughed so hard. Worked really good. He made it half way home before he noticed.

If I could give it minus stars I would! It fell apart before I could even use it. Once I put it back together it still didn't work...piece of JUNK! DO NOT BUY THIS!

It's way too small to fit in a car or truck exhaust properly to make the whistle sound. Fits in a 4 wheeler or side by side nicely, but that's not what i bought it for, so i was disappointed.

Best gag prank I have pulled! No one can figure out what’s wrong with their car until they go to mechanic!

Tried on several vehicles and no noise. Aside from that, it could do damage to someone's car

Put it in my sisters muffler and she drove it around for two days thinking her car was breaking down.

Too small for most cars. Had to duct tape it because I couldn't get it to bend without possibly breaking it

It worked but had to bend it a little to make it fit a larger exhaust pipe
