Had this on for about six weeks. Every time I turn the key I still grin. My mate has already placed an order after hearing mine.
The stock exhaust on the M140i is honestly embarrassing for what the car is capable of. This fixed that. Sounds like a proper performance car now and running it closed during the week then opening it on weekends is exactly the setup I wanted.
Always wanted a better sounding exhaust on mine and this delivered. Deep sporty tone that is not annoying to live with daily. Would buy again without question.
Product is excellent, sound is brilliant and build quality is clearly very high. Only four stars because shipping took longer than I expected. Once it arrived I stopped caring about the wait.
Spent a few months comparing options. Vortrix kept coming up as the best value for the quality you get. Can confirm that is accurate.
Two months on and still love it every time I start the car.
Heard mine at a meet and immediately asked where I got it from.
Quick delivery and the product is excellent.
Really happy with this. Does exactly what it says.
Absolutely love it. Car sounds incredible.
Genuinely quiet in closed mode which I was not expecting. Really well engineered.
Tips look great and the sound is perfect.
