Great, Kept sending updates on the package and quick delivery

Always a good experience when ordering from Valvetronics .

100% Recomended Can’t be more happy with the product.

Great company, great representatives, great product.

It’s always a little uncertain fitting a pipe to a car you haven’t experienced before but this pipe is incredible! It’s actually the perfect balance of totally mental and suitably discreet when required - it’s sympathetically supported by the Revuelto’s hybrid which allows the engine to sit at lower RPM reducing drone while still maintaining momentum. However - at the mid to top end it is golden era F1! 🤯 With this pipe you now play the car like an instrument - there are nuanced tones and crackles at different speeds, rev ranges and driver modes, of course it’s louder at idle and really slow speeds but the genius of the Revuelto and this pipe is slipping the car in to ‘E’ mode when you want to play it low key. Transformed the car - thanks Valvetronic 😎🏁

Great

great support and answers questions

Great service

I recently installed the Valvetronic exhaust on my BMW 540i, and overall, I’m very pleased with both the product and the experience. The sound quality is excellent — deep, refined, and gives the car a much more dynamic personality without being overly loud. The valve control system is impressively responsive and functions perfectly, even though it requires its own external electronics rather than connecting to the factory harness. Shipping was exceptionally quick, and customer service was outstanding. I accidentally ordered the wrong tips, but the team caught the issue and corrected it before shipment — a great example of attention to detail. The package even included some nice extras like a bracelet, which was a nice touch, although my included T-shirt unfortunately didn’t make it into the box. On the fitment side, installation didn’t require cutting the bumper, but the supplied clamps are somewhat visible since my car doesn’t have the M Sport body kit. The tips also sit a bit farther out than I’d prefer. Achieving a perfect visual fit would likely require either upgrading to an M Sport rear bumper or shortening and re-welding the pipes. Overall, this is a high-quality exhaust system with top-tier sound and responsive electronics, backed by a company that clearly values customer satisfaction. A few minor cosmetic adjustments — and making sure all included items arrive — would make it a perfect 5-star experience.

sounds magnificent. with the option to quiet it down a bit

Nice

I plan on buying more for next vehicles

Exhaust sounds absolutely mental and super stoked with it, literally zero rasp. When the exhaust valves are closed you can hear them rattling a little but though, and the exhaust did arrive with quite a few significant dints but I'd happy put down to damaged in shipping. Absolutely amazing, would buy again

Buying was easy and shipping was fast.

Shipping was on time as expected. Again Thanks Valvetronics!!!

Shipping was fast. They answered all my questions within a few hours of asking!
