I used Mike to replace 2 catalytic converters on my car. He did the 1st repair in a timely manner…read moreand gave me a warranty sheet to send into the company, Cateran and the warranty was supposed to replace the part if it went out before 5 years. The part actually went out before 12 months, and then he alluded that the warranty wasn't worth the paper it was printed on. If I wanted the part company, Cateran, to honor their warranty I would have to leave my car with him for at least 10+ days so that Cateran could get a warranty rep to come out. Needless to say there was no way I could leave my car for 10 days, so I had him replace the catalytic converter again and pay again. In the interim before the 1st repair went bad, I had him replace the 2nd catalytic converter. He used the same parts company, Cateran, and gave me a copy of the warranty to send into Cateran, which I did again. Now that the 2nd CC has gone out before 12months, Mike will not take my calls. Additionally, I have reached out to Cateran regarding their warranty (email response only, no phone#) they have not responded as well. Buyer Beware!!

I had an aftermarket exhaust that another shop installed for me that caused drivability issues…read moreabout 3 years. The issues started showing up after I had the exhaust installed but I wasn't sure if it was actually caused by the exhaust. The issue was the exhaust vibrating during wet rainy days when cruising on the highway severely where it bashes against the chassis causing the car rear end to fishtail where I have to slow down and focus to keep it in the lane on the highway. My personal mechanic helped me confirm what the issue was and showed me on a lift that my exhaust was merely millimeters away from my drive shaft. She showed me the exhaust was mounted kind of crooked and an exhaust specialist can help me correct the fitment. I was disappointed with the previous exhaust shop I had the exhaust installed at so decided to try a different establishment and found my way to Haddad Discount Muffler which wasn't far from the previous exhaust shop I initially got my exhaust installed at. My biggest problem with the other exhaust shop is that the owner just lets his junior do everything practically unsupervised which lead me to the situation I was trying to resolve. The owner of Haddad Discount Muffler took more of an active role. After I described what was happening with my exhaust and showed him where the exhaust was rubbing, he told me what he can do to resolve it. I ask him about the price quote because he doesn't except credit so I will have to used debit, I had to make sure the job was within my means to pay. He quoted me between $100 and $200 which was a safe range for me. I then told him the exhaust tips was crooked, and I can never get them to be symmetrical. He said he can adjust them and spot weld them, so they stay in place. I then finally told him I got new tips in the back of the car and that is when he said, this may affect the price as he has to see how well they fit. Now he got his junior over to work on my exhaust. I was worried as I can never seem to get the people with the most experience to do the work, but the owner took an active role. He told his junior where to cut, where to weld, he shifted everything into place and lined up and measured everything meticulously and kept asking me if I'm happy with where everything was sitting. I was happy to see him measure the distance the exhaust tips sit from each other and how far the sit from the side and top of the bumper. The replacement exhaust tips I have given him to install were much shorter than old cheap tips they replaced. Mike was skeptical that they would fit but I told him they don't need to protrude if they hug the bumper neatly, I would be happy with it. When he was done, the quad exhaust tips were sitting tight and symmetrical within the bumper, vastly improved over the way the previous tips fit. He had his junior spot weld them in place, so they don't shift but allows for easy removal if taken to exhaust specialists. The price ended up being well under $200 and I was very happy with the job.

If you want it done right and with an honest price I would highly recommend this place of business.

I rarely leave reviews. As a business owner myself, I understand the impact they carry. Four years…read moreago I gave Atlanta Speed Shop five stars and meant every word. Julius and Justin had stepped in to rescue a build on my 1967 F100 that a previous shop had majorly dropped the ball on -- a project that had already cost me over six figures. They were thorough, honest, and went above and beyond. Over the years I referred significant business to them because of that experience. When I acquired my 1968 F100 and was ready for a new build there was no question where it was going. I trusted them with it because they had earned that trust. This update is not written out of frustration. It is written because other customers deserve an accurate account of what happened, and because I exhausted every private option before going public. I brought my 1968 F100 to Atlanta Speed Shop in early 2026 for a significant engine and drivetrain build. I sourced the crate engine and select components directly. The shop handled the transmission rebuild through their own vendor, all remaining parts, and all labor -- totaling just over $10,000 on their invoice. My total investment in this project was well in excess of $20,000. Within the first day of having the truck back I noticed a loud screeching noise on right turns, a throttle that stuck twice, driveshaft scraping, a whining rear end, and oil spots. I reported everything to Justin in writing immediately. The truck went back for its first warranty visit. It came back still unresolved. Following that return the AC stopped working and a shop mechanic was dispatched to my home to fix it -- a basic item that should have been caught before the truck ever left. Julius had signed off on it. The truck continued to have issues. A significant driveline vibration then appeared under hard acceleration that had never existed before this project. The shop requested a ride along with Julius -- the same owner who had signed off on the vehicle multiple times already. The truck went back for a second warranty visit where Julius confirmed the muffler was contacting the driveshaft -- a direct result of their exhaust work. This was consistent with what Justin had already acknowledged in his own words in a text message. The vibration was resolved but the exhaust remains unfinished. A cracked frame rail near a critical suspension component was also disclosed to me for the first time at this visit -- despite the truck having been in their shop multiple times with Julius signing off each time. Today's warranty tow cost me $503 out of pocket -- an expense that should never have been mine on a warranty visit. When the final invoice arrived a 3% credit card fee appeared that had never been disclosed or applied to either of my two prior payments on this same project. Justin acknowledged it and waived it in writing -- because he knew it had not been disclosed. The invoice was never signed by me and the terms were never agreed to. If a response to this review claims these issues were pre-existing I would ask the reader to consider -- if that were true, why were they never disclosed across multiple visits and multiple sign-offs by Julius? Justin acknowledged the exhaust running the driveshaft in his own words after the truck had already been delivered as complete. These are not my characterizations. They are documented in the shop's own communications. The technical capability here is real and my 2022 experience was genuinely excellent. But capability means nothing if the work is not checked before it leaves the shop, warranty issues are disputed rather than resolved, and a loyal customer who invested well in excess of $20,000 and referred significant business to you is treated the way I was treated when things went wrong. I have documentation for every word of this. Future customers deserve to know.

Promises, not performance…read more Caveat emptor. If you have a lot of money ($100,000+) to spend, have no time limit, and like to hear the same canned excuses for why your car isn't ready as repeatedly promised, this place is for you. If you are considering using this business, do your research first. Look at multiple sources. Look at public records. UCC filings. Bankruptcy filings. Civil tax liens. How many recent good reviews are there and for how big a job? Notice the common themes of the critical ones. Then read the tone of the owner's responses, consistently disparaging clients who expressed dissatisfaction with their experience. My own recent horrible experience was very much like the others. But 10X worse. Maybe yours would be different. But be prepared for the same 5-6 tired responses to any problem you have, and then for personal insults. UPDATE: our car was picked up (unfinished) and trailered straight to a reputable shop in Marietta which has been here 40 years for inspection and evaluation of the work allegedly performed. They went through every charge for parts and labor. We discovered that the job done could have been done for HALF of what we paid. And the quality of work was unremarkable. Now, we have to put at least $15,000 more in to fix all of the new leaks and unfinished work, including three of the initial things we brought the car in for. (Window, lights and AC) Examples of work done before that needs to be redone now: Modify shift linkage to clear exhaust pipe transmission kick down linkage missing, replace transmission fluid leak from cooler line at back of transmission may need to have a new line made Parking brake cables need to be attached; cable is missing Both rear freeze plugs leaking Brake lights and turn signals not working (they worked when we brought the car in) Reseal both valve covers due to leaks Again, caveat emptor.

From the moment I met Richard, the owner, I knew I was in good hands. He is incredibly personable, professional, and truly knowledgeable. I honestly thought my car was beyond repair--it would drive fine one moment, then suddenly lose power and shut off, especially at stop lights. It was an unpredictable and frustrating issue that no one had been able to figure out. But Richard took the time to thoroughly test drive my car and was able to pinpoint the exact problem. That alone gave me so much confidence in his expertise. Not only did he fix the issue, but his pricing was very fair and affordable. What truly set him apart, though, was the care and integrity he showed. A few days after the repair, he personally called to check and make sure everything was still running well. That level of customer service is rare. He and his wife are truly gems--honest, dependable, and genuinely committed to helping people. My husband and I are beyond pleased, and we can confidently say: we have found our mechanic! If you are looking for someone trustworthy, knowledgeable, and affordable, do not hesitate to visit Shields Repair Shop. You will not be disappointed. Highly recommend!
