Does Honda have stainless exhaust?
If you are discussing the pipes--the answer is NO. There may be some exceptions such as on the newest most expensive models. It's my guess that the only thing on those exhaust systems that are stainless are the short sections of pipe that come from the back end of the muffler to the rear of the car--it's mainly for show. You can buy the same pipe at Honda dealerships. I don't know the cost.
