I took some video of inside the cabin of my E90 330i. I have a Magnaflow muffler #12148 with a res delete and Injen intake. It's just regular driving with no crazy street racing. The freeways around my house really suck as you will see in the video. You can also hear my squeaky rear wheel at low speeds. Enjoy!
how much did you pay to weld magnaflow muffler?
