They charged me $200 for the original FlowMaster not-so-Super 44 install for 2.5" aluminumized piping from the junction just downstream of the cats, to the new muffler, and again from the muffler back to the SS tip I put on. When I replaced the Flowmaster with the Dynomax, they charged me about $220 to install the bigger muffler (I do not know exactly what piping was replaced that time, though).
So $190 is a good price, Eric. Good luck!
