Our 4 into 1 Systems are unequalled in performance. They provide higher horsepower outputs and smoother, more balanced engine operation. The collectors are hand ﬁnished for smooth transition giving the exhaust a higher ﬂow and velocity rate. All our 4 into1 systems incorporate ball joints in every exhaust pipe going to the collector. This results in increased system longevity without sacriﬁcing performance. Designed and constructed using leading edge technology and the “AERO-POWER” brand assures quality manufacturing and testing.
4 into 1 Exhaust offers:
- Significant performance increase
- Smoother and more balanced engine
- Closer EGT temperatures
- Lower db levels than standard exhaust systems
These higher performance systems are available for most RV’s 6, 7, 8, 9 with O/IO -320, -360, -375, -390 4 cylinder engines.
