Exhaust repair service near Hamilton, OH

I can't say enough about the professional service every time I bring in one of my Mercedes. For both old & newer cars, diagnosing the problems, finding the parts and fixing everything to perfection, with personal attention, is a perfect combination. Ricky & his team run a great organization and I recommend them to everyone!

This is a two-man shop with Scott mainly up front and Sandy mainly in the back. I have found the two to be very honest and straightforward. Given a small independent shop, they perform routine maintenance as well as manage to track down automotive gremlins. And if the gremlins recur, they are very fair about redoing and rectifying. Rates are more than fair. And NO gouging. No free loaners, but will work with Enterprise rental for reasonable price, if necessary. I have been using this shop for several years for cars including: 1995 Saab, 2005 VW Passat GLX, 2012 Volvo XC70 (still under warranty, but little things), 2015 Volvo V60 T6 (also still under warranty, but little things also including intermediate oil change between recommended 10K gratis change at dealer). Though reluctantly, they will work on USA domestic marques with a bit of pleading or coercion. Recommended......Velocitoro

All Speed Innovations aka Sigma Six Engineering is ran by a wanna be engineer named Pat Smith. Pat uses customer cars as his personal cars while in for service. They charged me for a alignment and the alignment wasn't done. They also took it to a alignment shop without my permission. When they installed plastic TGV deletes they connected a ground wire to them. Pat couldn't figure out how to connect his laptop to my car and disable the TGVs, I did this myself after reading how to do it on the Internet. They also built a cage for a customer and ruined the customers car. Everyone should stay away from this shop or anything related to what Pat Smith does.
