Those shops just didn't want to take the time. idiots.
Find a muffler shop that has "car guys" working there. Talk to them ahead of time and see if they could have you come before /after normal hours for a "donation".
Just be sure they lift the car correctly so no damage is done. Heck, have them go onto the Pelican site while there and see how it's done.
I still give a blip of the throttle when I pass by the shop that did mine.
