The cornerstone of any well engineered diesel performance upgrade plan is a dyno-proven MagnaFlow Performance cat-back exhaust system. Offered in "turbo-back" "cat-back" or "downpipe-back," all Magnaflow systems are proven to make significant gains in power. This year, in limited applications, a 5-inch mandrel-bent systemis added to the lineup. All systems include a polished stainless steel, straight-through, wide open performance muffler and all the necessary hardware to complete the job like a pro.

NOTE:Some diesel vehicles are equipped with factory installed catalytic converters. Removal of a catalytic converter is prohibited by federal and state law.
To upgrade to the next level of power and performance, consider adding a K&N Filter Injection Performance Kit to your order, now available separately.

The increased airflow provided is an ideal complement to MagnaFlow's Performance Exhaust system and increases power and performance without sacrificing reliability or fuel mileage. Add one to your MagnaFlow Performance Exhaust system order and hang on. To flow more air out with a new Magnaflow exhuast you have to bring more in with a Performance Intake.

In addition, it is backed by the best warranty in the business.
For the ultimate increase in power, consider adding an Electronic Performance Tuning system, available separately from your MagnaFlow Performance Exhaust system.

These electronic enhancements install in minutes and increase power dramatically and safely by optimizing the factory settings for fueling and injection timing. Towing power is significantly increased and in many cases, over +100 extra hp and +200 extra ft/lbs of torque will be at your disposal. These products also increase fuel economy by producing more efficient engine conditions. Learn more about Diesel Tuning Today!
