    It's no secret that some things simply work better. Take for example your exhaust system. An aftermarket exhaust offered by Injen is one of those things that are better, yet we consistently insist on making life complicated. We stick to the original parts, even though the restrictive design of the OEM exhaust will hardly let your vehicle perform to the best. Those who already have an Injen exhaust system know how dramatically it can improve the performance.

    Injen Technology's Super SES exhaust systems are dyno-tuned with their intakes to deliver maximum gains in horsepower and torque. Each SES exhaust system is made from 304 stainless steel to ensure long service life. All the tubing is mandrel bent to make sure the inside diameter remains constant. And don't forget that Injen designs exhaust systems for each specific application so that the fit is just perfect.

    Great Product
    I ordered my cold air intake on a Saturday, it was here by the following Friday. It was very easy and took roughly 30 minutes install. It sounds awesome, looks great and works even better! Fuel mileage improved and I noticed the increase in power instantly. I'd recommend it to anyone!
