I've had several setups and hear most of them. MSR is by far my favorite and most would agree when they hear my car. I have a prototype. @m6beast is who to talk to.
It's deep and aggressive outside while still maintaining interior comfort with very minimal to no drone. It's amazing!
If you aren't looking to spend much then I would suggest the Turner or Fabspeed Muffler Delete. Sounds good but nothing compared to my current setup.
This is my car with Turner muffler deletes and stock Downpipes and cold start active. Drones around 1800 but as long as you are in D3/Sport Plus it stays out of that range while cruising
Here is Turner with Catless Downpipes and stock resonators. Loud as Fuck!! I had to delete cold start and drone was a mother fucker around 1800.. Neighbors and wife hated me. I loved it
