ATS Diesel 4″ Dual Exhaust System Cat Back

An exhaust system is one of the first upgrades we recommend for improved performance and lower exhaust gas temperatures for your diesel truck. The muffler restrictions in factory systems remove noise, but create back pressure and raise exhaust temperatures. ATS Diesel Dual PulseFlow Exhaust Systems feature a “straight through” design. The ATS Diesel 4″ Dual Exhaust System Cat Back is a Dual-wound, triple-mesh fiber component allowing for maximum performance and awesome sound! Our exhaust systems can drop exhaust temperature as much as 200°F over the stock exhaust, with a 10-30+ horsepower gain.

If you have a dual stainless exhaust system, install our dual chamber muffler and benefit from twice the pressure drop, and even lower EGTs.

ATS PulseFlow exhaust systems feature: 4″ mandrel bent 409 stainless tubing from the turbo back. Over 1″ clearance down the back of the firewall. Polished stainless muffler. 5″ diameter, slash-cut end with radius roll, 24′ length, polished 304-type stainless tips that can be positioned to any custom length and clamped into position.

Features and Benefits:

• “Straight Through” Design
• Lower Exhaust Temperatures
• Boost in Horse Power
• Stainless Polished Finish

Dual vs. Single Exhaust Systems

Have you ever wondered if dual exhaust systems are quieter than single exhaust systems? Well, you are not alone Diesel Tech Magazine writers has asked themselves that very question and have gone out to find the answers for you. It seems that dual exhausts are not necessarily quieter, but they do have less in-cab noise and less of a drone.

The reason for that is that sound waves in dual exhausts end up splitting between each side of the vehicle so noise resonating back into the cabs is often canceled by opposing waves.  However, outside of the cab a dual exhaust can be just as loud as a single, with 5” exhaust being typically louder than a 4” system.  It seems that control of noise levels then really comes down to finding the right muffler. Diesel Tech Magazine recommends Banks Monster Exhaust Systems and BD Diesel Mufflers.
