I recently purchased an older Blazer with a dual exhaust that looked like it took a big rock to a section of pipe and was missing a hanger. The dual tips didn't line up well at all, either. After reading the positive reviews here on Yelp, I stopped by Mad Hatter the other day and met Angel and Mark who quickly (and cheaply!) fixed all of my issues while I watched. The exhaust tips now line up perfectly, and they replaced the dented section of pipe. I would absolutely recommend these guys to anyone and will definitely return if I need any exhaust work done in the future. A 5 star shop!
