Was debating between the interior section and here for this question, but figured I would get more first hand accounts here. Mods please move if so desired. For those who have done intake and or exhaust upgrades, how is the cabin noise as it relates to making phone calls? I do paving sales and am in the car a lot of the day and fielding a ton of phone calls. I want to add some power and exhaust note, but not at the expense of not being able to use the Bluetooth system in the car for phone calls. Can you share some of your experiences and thoughts? Thank you.
