I had mine done at the local Meineke shop and was very satisfied with the work they did and what they charged to do it. Keep in mind that franchise operations like this can vary widely from location to location. See if you can find any local reviews or recommendations from friends who have been there.
Yeah took my 74 camaro to a Meineke for a custom exhaust, and then my 92 jeep wrangler when I needed some exhaust repair work. They have always done a pretty good job at fabing up stuff for me. I plan on having them do my exhaust tips for me.
