Hi Mike...how's the ECB bull bar working out. I had an experience much like Big Swedes, only my original choice was a Magnaflow. It performed great with its straigth flow thru design, but it was obniouxsly loud at idle and around town. I added a glass pack resonator, but saw little improvement. Finally, a friend recommended a muffler shop that sells a lot of Dynomax. He told me the Super Turbo was by far the best choice he recommended for increased performance and mild noise. I chose the longer body as well and I couldn't be more pleased. It sounded better than I thought and performance is better in mid 3000's RPM range...great for highway merges and passing. Otherwise, you barely even know it's there. Good luck. Oh yea, I also increased tailpipe from cat back to 2.5".
