Upgrade your exhaust system with the SuncentAuto 2.5" Catless Downpipe Exhaust, designed for select INFINITI G37, Q50, Q60, and Nissan 370Z 3.7L V6 models. Built from durable T-304 stainless steel with a mirror-polished finish, this performance downpipe helps improve exhaust flow, reduce restriction, and deliver a deeper, more aggressive exhaust tone.
T-304 stainless steel boasts excellent heat resistance and corrosion resistance, enabling it to withstand the high temperatures and moisture erosion of the exhaust system for extended periods. It is resistant to rust and cracking, extending its service life far beyond ordinary steel.
The inner walls are mirror polished, resulting in an extremely smooth surface that significantly reduces frictional resistance in the exhaust airflow while enhancing oxidation resistance. Furthermore, it gives the exhaust system a clean, high-performance appearance, improving the visual appeal of the engine bay.
The original three-way catalytic converter generates significant exhaust back pressure. This downpipe exhaust features a direct-flow design without a catalytic converter, allowing exhaust to flow more smoothly and improving engine breathing efficiency.
With reduced exhaust back pressure, the engine can "breathe" more efficiently at high RPMs, resulting in more complete combustion. In actual driving, this translates to noticeably lighter acceleration in the mid-to-high speed range, with a perceptible increase in wheel horsepower and torque.
Catalytic converters accumulate a significant amount of heat. After removal, exhaust can be directly discharged, resulting in faster system cooling. Under full throttle or sustained high load conditions, exhaust gas temperature (EGT) drops by an average of 100–200°F.
By reducing exhaust back pressure, the engine spends less energy pushing exhaust gases out during the exhaust stroke. This lowers pumping losses and improves thermal efficiency, resulting in a 3–5% fuel economy gain.
The catalytic converter-free design helps create a deeper, louder, and more performance-oriented exhaust note, ideal for drivers seeking a more responsive and exhilarating driving experience.
This 2.5" catless downpipe exhaust fits the following vehicles:
