2PCS Turbo Sound Whistle Simulator, Aluminum Alloy Blow off Valve Muffler Sound Booster for Auto Exhaust, Car Roar Maker Tail Pipe Whistle, Styling Running Accessories for Most Cars (Red)

This item is terrible , they do not work!

Suena bien

The product does not work, I bought 2 sets. Tried it on 4 different cars and not one work. I buy at least 2 to 3 products from Amazona per month from but, I have no faith in returning products. You spend so much to returning a product to get it back to Amazon, but you never get refunded.

Not working

Easy install, doesn’t sound like a turbo, more of just a scream or loud whistle. if you want to annoy people around you, then get this.

You hit the gas and rev in and nothing comes out. No sound just your regular exhaust. It’s a pos and don’t waste money on it

Don't waste your money and time, this product does not work! I installed this on my vehicle according to the installation instructions and it did not perform at all. I do not recommend this product!

Sometimes you can hear the whistle and sometimes you can't an you have to clean it up to 3 times a week
