Being new to the area, I was not sure what my choices were for some custom exhaust work I wanted more information about. I chose to visit Mark and Pat at Mr Muffler in Warren, MI. I was not disappointed. They were straightforward in telling me what their years of experience had taught them about custom work and they gave me valuable information. I'll be going back shortly to have more work done. In the end, they performed a muffler delete on my new '14 GMC Sierra with future promise of doing a complete custom exhaust system. The workmanship was top notch (I inspected it myself), professional and they treated me like family while I was there. I'd highly recommend them for all your needs. Oh, and the truck sounds great too ;-)!!!!
