“Put this on my M2 and honestly couldn’t be happier. Fitment was good, welds looked tidy and it sounds unreal compared to stock. Valves work well too, so it’s not obnoxious all the time. Open it up and the car sounds heaps better, much deeper and more aggressive. Makes the whole car feel way more alive. Definitely one of the better mods I’ve done.”
