    Significantly different from its competitors in performance, feel and ride, the Lexus GS offers a blend of everything that matters in a car: quality, comfort and of course legendary Lexus luxury. If you’ve been considering working on your Lexus GS a little to get its oomph on the same level as its undisputed luxury, a new custom exhaust system will be of help. Built purely for performance, custom Lexus GS Exhaust Systems offer what the stock exhaust cannot give: better performance and greater power. They operate by increasing exhaust flow, opening up space for clean air and fuel to flow into the engine. The two are what the engine uses to generate power and as the custom exhaust upholds their consistent flow, it becomes easy for the engine to generate more power. Get premier exhaust systems from CARiD and enjoy choosing from a wide variety of custom built exhaust systems and components.

    In stock are all the major brands, starting with MagnaFlow and its dual split rear exit cat back exhaust system for the Lexus GS and Borla’s split rear exit Lexus GS cat back exhaust system. Performance exhaust components available include mufflers, cats, clamps, tailpipes, tips and headers and header collectors from Flowmaster, Gibson, Onki, MBRP, Weapon-R and the two brands aforementioned. A complete exhaust system, fully replacing the stock exhaust, will reward you with 7-10% extra horsepower and torque. Add a performance header and any of the other components available and you get an additional 20-40hp. By buying a custom GS exhaust system, you will also be making indirect savings. Here’s how: all Lexus GS exhaust systems from CARiD are built from durable stainless steel and do not wear out easily. They will serve you for years, eliminating the need to ever replace them.

    Oxygen Sensor
    This is a genuine product that is new. The product did serve its purpose and I saved $450 from not buying a Catalytic Converter. I am happy with the part and will continue to purchase items from CARiD.
