I drive a 2007 335i and I just had the deletes done yesterday. I had the shop replace the resonator with pipe and im running stright out the back with stock tips. Total cost 185.00. Took them about an hour and a half and had to pay for piping. Holy ball$ is it loud! Sounds really good and honestly with music on the drone is not horrid. But people will know when you hit the gas. I kept the cats in and i have a stock dp. I love it. Really depends on who you ask. I personally like a loud exhaust. It doesn't sound like a ricer either.... and honestly the exhausts that do sound ricey are still on a bmw at the end of the day.
