Mufflers repair service near Owensville, OH

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.

Mark and his guys really helped me out! They went the extra mile to get the lowest cost for parts, knowing cost was sensitive. They explained everything and made it as painless as possible. I am never taking my car anywhere else!!

Sooo helpful! Best mechanic around! Super affordable! Explained everything so clearly! This is the only mechanic I’ll use for now.

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
