            Update: Spoke with Scott at Stromung.
            1. He will send pictures of the tips he can offer
            2. He will present a discounted price
            3. He recommends the standard muffler for those of you NOT driving a convertible as feedback from customers states they would not want it quieter.
            4. Please update this informational list with QUIET or STANDARD muffler.

            Thanks guys.
            We are getting close now!!!

              Did Scott say if their quiet version would still be a little louder than stock 325i/s catback? That is what I want, just a little more volume than stock.

                The quiet is substantially quieter than standard? Possible for sound clips?

                  I emailed Scott and communicated I'm looking to make my car just a little bit louder than the factory catback. He said if you have a "hard top" aka non convertible the regular one is perfect.

                  Put me down for STANDARD

                    Scott at Stromung said they add a baffle for convertible mufflers. Seemed to strongly recommend verts only, otherwise it's too quiet.

                        Are you running a catalytic converter? If not and no resonator your car is already starting louder than factory.
