Lighter, more efficiency, more power, more durability. These are just some of the ongoing goals of our exhaust system division. We firmly believe that the exhaust system is one product on the vehicle that should never be compromised. A premium exhaust system should, when possible, be used from the start to avoid any premature changes a few years later. Many new engines have been engineered extremely well and hastily developed systems have been shown to actually lose power. APEX exhaust specialists toil long hours in the art of exhaust gas flow. Every category of manufacturing is analyzed including CAD design, materials, welding quality, exhaust gas dynamics, engine compatibility, and real world use. Our exhaust systems are considered one of THE standards in our industry. Proven quality outlasts anything else. Experience the standard of quality that tens of thousands of satisfied customers already have. All A'PEX exhaust systems comply with applicable emission laws since they neither modify nor relocate the required factory emission control devices; they are considered "direct replacement" parts. Such parts do not require a CARB Executive Order (EO) since they are not "add on" or "modified" parts. A'PEX exhaust systems are "functionally identical" to the OEM parts during emission tests. Sound levels are tested on stock vehicles before the product release to ensure compliance with the 95dB limit.
