Bought them direct from stromung website . Seemed the cheapest place at the time .
I like them . They seem like a decent middle ground between stock and something that's too loud. Also reasonably priced / well made . I Only really drive the car at weekends or to shows , and enjoy the extra noise over stock . I don't find it to intrusive when cruising , and when you push on they sound good . Not sure if id want them on a daily . But then again I probably wouldn't want to be driving the m everyday anyway .
Exhaust sound is defo a personal thing , some may love what others hate . Only real way to know is to experience 1st hand . Almost impossible to tell from videos .
