    Juan, was VERY accommodating with my Schedule and able to diagnose (quickly) and replace the parts from my Muffler to my tailpipe. PLUS, he helped arrange for a car rental, since, I had obligations during the weekend. To demonstrate the required repairs, Juan showed me the damage that needed repair/replacement.
    Best quality in everything, had my 05 Subaru R.S modified by these guy's. Excellent work keep it up
    Very impressed with the service, price, and results on my exhaust system. This is my new muffler shop.
    Woohoo! As good as it gets! GREAT honest guys! And they do more then just Mufflers, they do Brakes, Oil changes, etc...

    Proper maintenance helps prolong the life of your vehicle.

    Drivers often learn the hard automotive lesson when they have to bring their vehicle to their auto center on a tow truck. A little routine maintenance could have prevented a breakdown. The key to good vehicle maintenance starts with the oil change. When you go in for a full service oil change, your tech will check all your fluids. If one of them is low, he can look for the reason why.


    One might say the most challenging part of repairing a vehicle is diagnosing the problem.

    More →

    Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. It’s challenging to track down the actual cause of the problem and it can be frustrating for the vehicle owner because it can take time to get to the bottom of a problem. If it’s not something obvious, it’s easy for drivers to focus on the fixing and not the diagnosing.


    Upgrades are a great way to customize your vehicle to be unique and the way YOU want it.
