I'm selling my GMG exhaust and Downpipes, because i no longer have my S5. However, let me tell you that this is the most amazing sounding setup in real life. It doesn't sound anything like the militek, AWE, stasis, etc. That's the beauty of it, and the performance gains are phenomenal. If you are interested in buying my exhaust...please contact me... I'm asking 1600 negotiable.
