The cornerstone of any well engineered diesel performance upgrade plan is a dyno-proven MagnaFlow Performance cat-back exhaust system. Offered in "turbo-back" or "downpipe-back," all of our systems are proven to make significant gains in power. This year, in limited applications, we've added 5-inch mandrel-bent systems to our 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.

In addition, it is backed by the best warranty in the business.

For the ultimate increase in power, consider adding a MagnaFlow Performance Tuning system, available separately from your MagnaFlow Performance Exhaust system.

These electronic enhancements can be installed in your driveway and increase power dramatically and safely with no compromise in reliability. Towing power is significantly increased and in many cases, over 100 extra hp and 209 extra lb. -ft of torque will be at your disposal. These units are specifically built to MagnaFlow specifications and are extensively tested for power, reliability and driveability.

NOTE: Tuning products are not exempted for on-road use in California and maybe illegal in other states.
