Fast shipping and great product! Highly recommended!

Sounds good but I have to turn it on every time I start the car

Yea , I like it🤘🏻⚡️👌🏻

Quick delivery, easy install and great quality

Well the f80 has got a reputation of sounding a bit well,rubbish.

This is a good option to improve things without spending thousands on a new exhaust pipe that you may or may not like....its a gamble and very subjective.

I would definitely recommend going down this road before changing out parts as you might be pleasantly surprised......This is how it should of sounded from the factory with the valves fully open.

Its an easy product to install,the only negative is that we in the uk have to pay import duty's so bare that in mind when ordering.

Overall I can recommend this product and have done to a few friends.

Super easy install very satisfied with the result subtle increase in sound / volume definitely recommend if you don’t want raspy in your face wake up the neighbours this is the way to go.

Awesome company.

Awesome cheap upgrade. Gives my 540 a much nicer deeper tone. Took about 1 minute to fit. Highly recommend.

Easy to

Great thing.
Just what I needed. I can open the valve when I want to just to get that extra little tone from the exhaust.
Very satisfied

Love the sound with flaps open. Also like the ease of installation.

Great upgrade

Works great but the A45s is still quiet without removing the GPF, even with an aftermarket system and the mode11.

Fitted this part in a few minutes
Works well
Louder than it was
Hsppy with product
Fast delivery from Australia🤗

One of the best mods I ever came across for the Val control, no wires needed 5 star.
