It will work, but not always be the best. This shop takes pride in the work they do. Owner is friendly and personable. I even chatted him up regarding welding, and he openly took the time to teach/show me some things to try as practice to learn better welding. This was not even related my my job!! I consider my job pretty simple... for my skill level (shade tree mechanic). I did not want to deal with it in my driveway. So I needed a shop that I would trust to do it as I would do it. I would take my time and get it right. No Wham,Bamm thank you mamm stuff. Here is an example of the little details you want in a professional shop. When putting on the clamps for the exhaust tips the owner (Sorry, I forgot your name, my bad) rotated the clamps in such a way that they would never be noticeable (clamp bolts) from the rear. This car is low and it probably would not have mattered but I know from experience from other shops that they would have just slapped the clamps on. Would have it worked? Yes. "Professional detail" no. The details matter and that is how you know you are dealing with someone that cares about the service they provide you. My job was a Corsa cat back exhaust on a 2024 Ford Mustang GT. The owner knew exactly what he was doing. Not like some other shops where it just seems like the person is guessing half the time. I work on my own project cars. So I have a certain skill level and sometimes I am that person that is guessing on how to do something. This shop was none of that. Professional and knowledgeable all the way. I will be letting everyone I know about the shop for their exhaust needs. You get what you pay for. The prices at this shop are fair, competitive and totally reasonable. Seriously I felt like I got a bargain just based on how professional the shop was. Side note- The owner has legit welding skills too. I saw examples. I would not hesitate for him to weld anything I needed done. NOT RELATED TO THIS SHOP AT ALL... Just a personal rant about some Yelp reviewers... Again NOT RELATED to this shop or any reviews of this shop...My two cents on Yelp reviews overall where people say they felt over-charged or they know they can get something cheaper. Look, you are paying for someone's skill and overhead (of the business). Stop thinking it is okay to scr3w skilled professionals of their labor because you think it SHOULD cost less. Seems you do not have the skills or understand the knowledge need to do skilled jobs you want someone to preform for you. First off just remember EVERYTHING is more expensive now. Then there is a big difference between doing a job correctly and doing a hack job that will be "good enough'. If you are one of those "good enough" shoppers, then stop leaving bad reviews all over Yelp for business that are actually trying to give you a professional and correct service. Those businesses are NOT trying to rip you off... they are trying not to screw you with shoddy service,

I can't imagine anyone saying anything negative about Russ and Eric at Steve's Machine…read more I had them do a VW 2332cc engine for my desert car. The way it knocked and with little to no oil pressure, I figured it was junk. Russ took it apart and assed the damage. In his opinion it wasn't nearly as bad as I expected, and I was ready for the worst. He installed a new crank, fit new main and rod bearings with new rings and a valve grind. I had a practically new motor at less than half the price of a new. Three years of abuse later, it's still running strong and doesn't leak a drop. That gave me the confidence to have them build a Pontiac 462ci for my 67 GTO/Le Mans. At his shop, Russ sat down with me over a cup of coffee and gave me his full attention. We discussed my new build, and he gave me his opinion about some of my choices with really good reasoning. Some of his ideas gave me more performance at little to no extra cost. He saved me money on unnecessary over building, while also advising on weak areas. During the build he showed me on my engine, extra things he does on all motors. Shimming lifters, spec'ing ARP bolts, dialing the valve train, and milling the intake manifold to name a few. He doesn't cut corners; I don't think his conscious would let him. Once it was done, they broke it in on their shop dyno. They optimized the timing and fuel curve. It made 419hp @ 4800 rpm and 513 ft/lbs. torque @ 4000 rpm. It's ready to rumble. I go out of my way to recommended them, every chance I get. And for what I got, the pricing was more than fair and reasonable. Nothing but a positive experience. Also, sometimes if you want the best, you have to get in line and wait. That's life!
