"I've flown an AWI 4-into-1 exhaust about 800 hours on an IO-390. It's been a durable, trouble-free system. . . . It sounds great too." Dan Horton, RV-8 Owner read more
About 4-1 Exhaust
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 into 1 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.
