Very interested to see how it sounds without an x-pipe.

Here is a new video from today with the Challenge Rear Section Exhaust with stock X pipe. I also recorded decibel readings for numerous situations. If we are able to get our hands on a stock M3 this week, ill get some stock baseline levels for you. All of the levels are very reasonable on this exhaust All db readings were done at the industry/legal standard outside of the car: Outside 4,000 RPM: 84db 5,500 RPM: 87db 7,000 RPM: 91db In car 30 MPH Cruising: 53db 65 MPH Cruising: 68db 75 MPH Cruising: 71db Full throttle 0-60: 71db max Here is the same exhaust, but with a Challenge Race X Pipe installed for reference: |

I like how the exhaust paired with the x-pipe sounds. Very crisp and brings out the high revs notes the S65 makes.

that sounds good with just the stock x-pipe.
Nate, have you done any install in your facility? is it easy to remove the stock and slap on this exhaust? |

Yes the install is 100% bolt-on and takes about 45 mins total with a lift.
