love the the product totally worth it made me reconsider my decision to buy an exhaust ..... the only hiccup was i didn't push up enough and thought it was too loose but follow the instructions

Really easy to install and works as described.

Great product

Works as advertised and super easy install

Best mod for the price!

Works flawlessly and I even programmed the buttons to my home link.

Bought this for my m340i and i absolutely love the cold starts, and driving with the valve open in comfort. It adds a deeper tone or grudge when the valves are open at lower rpm. Use it on the highway and i cannot tell i notice any drone. Would recommend.

Awesome little addition. Really easy to install, didn't need to lift the car or anything. Super cool.

The sound is great, now I don’t need a mid-pipe.

No problem!

Definitely does turns it up to 11. Brilliant bit of kit. Im so happy with it and it saved me a hold load of money not buying a new exhaust system. 🤘🏽

Perfekt✅

Easy installation and great results. Works both with my stock and aftermarket exhaust from Grail.

Worked fantastic! Major difference in sound. Definitely recommend!

Arrived in short time installed in minutes no tools no fuss very straightforward and easy more importantly sounds great improve the stock exhaust sound much more throaty and more pops and berbles
