Isuzu Banks Exhaust Systems
Stock exhaust systems are designed simply to provide a conduit for spent gases to move from your engine to your tailpipe - no more, no less. On the other hand, aftermarket Isuzu Banks Exhaust Systems are engineered to maximize your engine's exhaust flow, giving you: serious horsepower and torque gains, distinctive growling exhaust tone and improved fuel economy. The problem with the factory installed exhaust systems is that they are not optimized for the best possible flow. Auto manufacturers spend much more time thinking about the shape and placement of your air vents than they do planning your exhaust pipes. An aftermarket make exhaust system will harness the potential power that your engine is wasting because of its inefficient stock exhaust.
When it comes to the improvements in the performance aftermarket exhaust systems can get you 1 or 2% overall increase in fuel economy. With an aftermarket make exhaust system you will not only feel the power increase but you will also hear it thundering and rolling around you. Nothing quite improves your vehicle's presence as a throaty, rumbling exhaust system. When you hear each and every piston firing in rapid succession, you truly comprehend the unbridled force lurking under your hood. Naturally, when you plan any upgrade to your exhaust system you must take care not to disturb existing emissions control equipment, no matter how tempting that would be.
Therefore a "cat-back" exhaust system is your best choice for your make as it would allow you to put large-diameter exhaust pipes and low-restriction performance mufflers into your exhaust system without harming the catalytic converter. With this type of system installed you would be maintaining your make within legal limits while receiving more torque and horsepower, less exhaust back-pressure, and a sportier sound.
