Jeremy, the owner, was very helpful. He installed a Turbo 4 inch exhaust pipe, a number of other things than afterwards. I had trouble with my truck, which a few push rods were bent rocker. Arm broken, he fixed those and got me on my way home. From washington state to southern california, very fast service.Great prices and a great guy to deal with.
I would highly recommend his shop to anybody that needs any work done. Mine was a diesel, but any vehicle he works on. He does. He will do a great job thumbs up.If there was ten stars, I'd give em a ten

They are always happy to see my husband coming for upgrades on turbos and such but also cheerful and ready to do mundane tasks like oil changes for me! They also go above and beyond, during a routine oil change they spotted a faulty gasket that would eventually cause damage. They worked with my warranty to get as much covered as possible! And in addition during the tedious repair process found some items with basic ware and opted to just replace now while they had the easy access the original repair had offered! And not to mention so quick with the work. A huge project as it was, plus some other things like another oil change and brakes, all only took 3 business days! FS and the team are our go to shop for the big upgrades and the basics!
