    The Mazda CX 7 is a sleek machine designed with state of the art technology. Its advanced features are configured to provide maximum comfort. This car is fitted with an ultra modern navigation system, rain sensing technology, blind monitoring system, remote keyless entry and start up among many others. You also have a choice between buying a 2.5L engine or the aggressive 2.3L turbocharged engine. Whatever your choice, both are superb vehicles with excellent capabilities. But if you are looking for top performance from your vehicle and revolutionary fuel economy, you need to replace your stock exhaust system with a Mazda CX 7 exhaust systems. The problem with all stock exhaust systems is that they restrict the free flow of exhaust gases thus hindering the engine from performing optimally. These inefficiencies come with a cost implication for you in terms of poor fuel consumption and the cost of obsolescence. Installing an aftermarket unit from CARiD is a sure way of keeping your dollars safely tucked in your wallet for a long period of time.

    Custom Mazda CX 7 Exhaust Systems have an efficient way of expelling exhaust gases and allowing fresh oxygen into the cylinders. This is achieved through reducing backpressure and turbulence in the exhaust system. The benefits this has include increased torque and horsepower gains to a tune of about 10%. You also get to enjoy significant fuel cost savings with increased mileage per gallon. This translates into direct financial savings for you. The aftermarket unit is made from stainless steel, a material resistant to corrosion. It also comes with a lifetime warranty. But the biggest high has to be the deep growl produced by this unit! The throaty, primal resonance is a distinct statement that you have moved up from mediocrity to excellence. Set yourself apart from the crowd by installing a custom Mazda CX7 exhaust system from CARiD.

    Hoping It Works
    The CARiD ordering process is stellar. From product search to selection and ordering, the site is very easy to use and fulfillment of my orders has been prompt. Unfortunately, the Direct Fit Cat-Converter was not sized perfectly. This remanufactured version was almost an inch shorter than the original part that needed replacing. I was able to max out the distance with a bit of play in the exhaust system overall, but would have liked to bolt everything back in place without improvising. For the price - and added value savings by repairing it with a friend - I don’t think I could have gotten a better value. This repair would be no less than $1500 at the mechanic or dealership. I will continue to shop at and refer people to CARiD, but I’m hoping that no issues arise by force fitting the short-sized Cat.
