Honestly don't waste ur money even if its a prank 
 Don't deserve one star either don't waste money he don't accept returns and piece of junk don't do any thing. 
 I installed and could not notice any change waste of money 
 THE THOUGHT IS FUN. BUT THIS IS JUST A STEEL WHISTLE. HARDLY HEAR IT. DOES NOT SOUND ANYTHING LIKE A TURBO AND SIMPLY LOOKS RIDICULOUS 
 Did not work but it's was cheep fun to give it a try 
 Sounds like whistle when the cars on. only when you rub your engine it sounds like turbo and the insert flys off with the rattling of the exhaust 
 DONT BUY ,SAVE YR MONEY PIECE OF GARBAGE 
 Not what I expected 
 Have to press hard on the gas to hear it
