The Megan is more of a NASCAR/ muscle car sound. The oem mod I heard was more euro high pitched sounding.
Spend the money and get the Megan. After having stock, then Megan, then eisenmann race, back to Megan, then gintani hybrid and finally back to my Megan; I personally love the Megan the most. It's dam near perfect "all around" exhaust for 500 bucks.
