RULE THE STREETS.

Few people in the tuning industry have not heard of HKS or Greddy, or have not seen the power and quality of Precision Turbochargers. We have built over 500 engines in the St Louis area alone, and our mechanical prowess has been proven at Gateway Raceway in Madison, IL, and other racetracks across the country. At Speed and Sound, we are an authorized dealer for Precision Turbo, HKS, and Greddy. We get pricing discounts that we can pass on to you that many other suppliers cannot. We also carry a full line of Tial blow off valves and wastegates, Vibrant Performance exhaust parts, specialty accessories and all the electronics (boost controllers, ECU’s, etc.) to get the performance you desire. Please click on the vendors name to go to their homepage, and visit our full vendor list page.
