I had a great experience here. I would recommend calling to make an appointment rather than doing it online. They gave me great affordable service and even brought me in the garage to show me the work and explain what was done. 10/10 highly recommend great customer service and great work

Did a great job on my Cobra. Installed a cat back and a mid pipe at separate times. Price was fair and they did a great job. Aligned the tips of my exhaust perfectly. Quoted me on the high side, but then once they looked at it it was much less.

—Alex Romero

This is very reasonable and they did a job on my vehicle thanks I found me a new shop for my repair needs.

When I first drove up I thought it was a small place. When they finished the extensive work on my car the same day I brought it in I knew then the size didn’t matter. They did an excellent job! They were honest and thorough and kind and professional. Colleen is absolutely fantastic! She knows more about vehicles than anyone I know! She made me completely feel at ease and was up front and presented options before completing the job!! If I need work in the future I can promise you I won’t be going anywhere else!! Fantastic!! Mechanics you can trust!!

This place did a phenomenal job on my 2020 hellcat. Colleen was very professional and punctual. The guy that did the work was very friendly. They both had great conversation and treated me with the utmost respect. I’m glad I didn’t believe the few bad reviews and took a chance on this place. My hellcat now screams the way it’s supposed to thanks to this shop. Don’t sleep on this place. They will take care of your exhaust needs.
