A few years ago in a local muffler shop just up the road from you, I had a new 2.5 exhaust system installed from the header collector pipe all the way back for a bit less than $200. This included a stainless glasspack to replace the cat, new Walker performance muffler w. one inlet / two outlets, and dual tailpipes exiting under the rear bumper. With new hangers and all welded. Would probably be less than $300 today. So yes, check with your local shop.
