In layman’s terms, a catback exhaust system provides a smoother, more streamlined path for exhaust gases to exit your car, allowing your engine to work more efficiently. When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio. Oxygen (O2) levels in the exhaust stream were therefore generally insufficient for the catalytic reaction to occur efficiently.
Our straight-through brushed-finished mufflers are configurable to your desire, smoothing the exhaust note to a deep growl, without adding restrictions, rasp or 2007 duramax egr delete drone. Strong high-quality bracketry and OEM-style clamps hold the system steadily in place, making the install or removal a snap, and fitment simple, yet precise. A cast 3" to dual 2.5" rear splitter creates an ultra-smooth transition, steadily feeding exhaust gasses out of the system, while looking tidy from under the rear bumper. Finally, removable 4" polished slash-cut exhaust tips finish the system, adding a classy motorsport-inspired touch to the rear of the vehicle. In addition to high-quality materials and components, the design of each high-performance exhaust system allows for easy, bolt-on installation right out of the box.

The only difference is that it features straight perforated pipes. The original exhaust systems focus more on just reducing the sound and not shaping it to give it that desired deep growl. One function shared with both the axle-back and the cat-back exhaust systems are shaping your vehicle’s tone.
Typically, that includes a mid-pipe, muffler, tailpipe and tips. Cat-backs generally yield increases in performance, due to the more efficient flow of exhaust through upgraded parts like larger diameter tubing and better flowing mufflers, as well as improved sound and reduced weight. For starters, the "cat" in catback exhaust system is short for "catalytic converter", a central part of your car’s emission control system, which cat back exhausts are fitted behind, hence the "back". This relatively simple mod helps to free up exhaust gas flow and improve the noise of your engine by swapping out part of your exhaust system with a specially designed
