If you are looking for a good place to go, I went to [censored]'s Hotrod Shop, located on County Road 70, east of Dodd. It is a part of [censored]'s Sanitation. The ownwer of [censored]'s Sanitation has a love of old cars and started a hot rod shop at the Sanitation site. I took my 46 there for exhaust this spring. It sounds like they took it off site to do the work, but I was VERY happy with the results. I could have probably done it myself, but sometimes, having others do the work is just easier.
Anyway..you can choose what you want as it is a rod shop and go with standard exhaust all the way up to stainless from front to back.
Stop in and talk to [censored]. He or his mechanics are usually in the shop during business hours. He is a square shooter and will tell you exactly what it will cost to get you what you want. He also has a bunch of cars to look at too!
