I got a 14815 looks a lot cleaner IMHO But to each his own the square dual tip actually came on the c36 AMG's was never a fan of that look. The magnaflow still drones a bit in the cabin not as much as when it was cats to straight pipe no resonator no muffler. but i also have a m104 inline 6 with the resonator deleted and twin high flow 4600 series magnaflow cats. so its a bit deeper sounding than the 4cyl NA'ed I have heard my same muffler i have with a resonator delete on a 230NA before, in person it sounds great. hes also a member here at club202, Calling OCKlasse haha. heres a video he has of it on youtube for reference
