I have two brand new in box Magnaflow 10426 straight through design muffler / resonators.
22" body length, 2.5" inlet and outlet.
These were purchased (without measuring properly ) for a F80 M3 exhaust however it became immediately apparent they would not fit where I wanted them.
Asking $95 each.

Google reviews on these resonators. They get rave reviews from 3" turbo catback applications, 2.5" NA G37 / 370Z, and big displacement V8 guys.
