No, I have everything from the primary cats back (the secondary cats and the resonator) straight pipe. I noticed in your other thread you said that you wanted to keep the AMG sound, but just louder. The setup I did is exactly what you are looking for. About a week later, no CEL and I LOVE driving the car around now in low gears. Anytime I get over 3500-4000 RPM and then back down the backfire sound is amazing.
