Muffler Delete with CPO?
I have a 2007 335I with aftermarket factory type warranty. I want to do a full exhaust but it is quite expensive. I have decided to settle for a muffler delete and I have a few questions.
1. Will I have issues with warranty while having a deleted muffler?
2. How bad is the drone in the car after the deleted muffler?
3. I have heard that have a DCI and a deleted muffler causes loss of low end torque?
