Reviews
Truly amazing service. I was a little worried given the price, but after having the car back for a few days, I can safely say it is definitely worth it. It's also worth highlighting that the staff were delightful, incredibly helpful, and informative, so if you have a car you really love and want to reduce road noise — especially a European car — you should definitely give these guys a try.

Dimitriy was incredibly knowledgeable and recommended the perfect solution for my new Golf R. The car is over 10 dB quieter now and drives more like a luxury car than a VW. Feels like a tank — it’s awesome. Thank you to Dimitriy and his team!
