Went to 3 shops today. Bought a tip, also ordered a new weldable O2 sensor flange:

Rod's Muffler in San Juan Capistano wanted $180 for catback, no tip.
Mesa Muffler in Costa Mesa wanted only $125 but that didn't include O2 sensor cutting/welding for the flange
Settled for Collin's Muffler & Hitch in Mission Viejo, $125 for 2.5" pipe all the way back, cutting and welding in my new O2 sensor flange, welding in my new muffler, and welding in the new tip I bought.
Having it done Wednesday, I will make a video and share it. I'll also post another after the month.
