Review on 🚗 Dewhel Universal Aluminum Turbo Sound Exhaust Muffler Pipe Whistle Car Blow off valve BOV Tip Simulator Whistler - XL-Black: Enhancing Your Car's Sound Performance by Hugh Starr

This is B4D4$$! I absolutely love it haha it's very funny to fool people on my 91 into thinking it's a Turbo/D haha. One piece of advice I can give you is PLEASE NOTE IT!. The part with a whistle at the end of the mouth, please add LOCK TIGHT, this will be my second purchase because I lost the whistle on the first one. Now that I know this is my first mistake, I now know I need to lock it because the lock you open with an Allen key doesn't fit very well. So please tighten it tightly, especially if you have a noisy muffler, the vibration will break it.
