  • “What a blessing it’s been to have found Rich. I bought my son a used 2014 Audi last year and the thing came with more than its share of problems. We made the mistake of going to a chain for our first major issue. The diagnosis seemed a bit much and I didn’t trust that they weren’t just looking to get paid for unnecessary work. I wanted a second opinion and we found Rich whose deep experience with Audis advised a different route that still supported the car repair but was more wallet friendly. Rich has been our go-to, trusted advisor & mechanic for any major repair since then. He’s knowledgeable, respectful, kind, communicative and honest. I truly cannot recommend him enough.”

  • “I found RDZ motorsports completely by accident when looking for someone that would tune my magna flow exhaust on my Tacoma. I had this annoying drone that wouldn’t go away. Rich took the time to listen to me and solve my problem and reconfigured my exhaust so that the drone went away . Anyone with a noisy exhaust Come and see RDZ motorsports. They know their stuff.”

    - Rich Salerno

  • “Rich did my exhaust on my C8 Corvette. He does excellent work, gets it done fast, and done right. Thing sounds incredible! He treats you like a friend you’ve known for years.”

    - Joseph Sacheli

  • “I talked with Rich a few time over the phone and email and he quickly set up an appointment for me as I was coming from a few states away . The installation was seamless and Rich is super knowledgeable. I was in and out in less than two hours with increased horsepower and torque!”

    - Bryan Norwood

  • “Rich a professional. Not only is his automotive work impeccable, but his approach to dialing in to what his customers 'needs' are , is second to none. RDZ mechanically restored my classic car and created a short term, mid term, and long term strategy to get it to exactly what I wanted. I'd trust RDZ with any automotive project. He's the best!”

    - Gavin von Loeser

  • “I had a custom aftermarket muffler put on my 2019 Honda Civic, Rich knows his stuff and it came out great. We discussed fitment options and I am glad to have gone with his choice. I also had new exhaust tips put on the car, which is aligned perfectly with the body. If you are looking to get some exhaust work, you found the right place. RDZ also uses 304 stainless steel piping, the best for long term durability against salt and other road debris.” - Graham Riss
