I wrote a very positive review in May of work done to my GT350. This is a follow up review of that work. I have to say that I pinch myself after every session on Track Days. I never thought I would own a fast track day car, let alone a Mustang GT350. I had mods done to the car to make it louder, faster and safer. MAXRPM had done an amazingly thorough job to do those 3 things and more. In only two Track Days at The Ridge in Shelton, I was able to cut 4 seconds off of the stock cars time I did Last year. MAXRPM had definitely come through for me. I feel really confident in the car now. I have taken the car back to have some maintenance and new tires, and as always Alex and his crew treated me extremely well. They are human despite their robot like perfection and professional demeanor, and are very approachable during the maintenance session and extremely helpful. During the check up, Alex told me of a design issue with the exhaust I had chosen for the car and which MAXRPM installed. I was unaware of the issue and surprised when I saw the problem, and even more surprised when Alex said there would be no cost on the exhaust modifications, he said it’s how they operate, they stand behind their work in all respects. I continue to be impressed and amazed by the work performed by this shop, I cannot recommend this shop any higher, they are the go to shop for high performance modifications or just regular maintenance. Thanks again to the staff and mechanics at MAXRPM.
