Horsepower without restrictions... Price within
reach!
The Active Autowerke Rear exhaust for the E46 M3 sounds, looks, and
works at a price that fits into anyone's budget.
Improves power output on N/A or supercharged E46 M3s.
From Active:
Designed specifically for the BMW E46 M3, the all-stainless Active
Autowerke Generation 4 is our most innovative cat-back exhaust to
date. Its precision-tuned straight-through design with in line
resonators offers an incomparable combination of power, sound and
styling. Well suited to both naturally aspirated and supercharged
vehicles, this new and revolutionary design employs inspired pipe
routing and optimum diameters to enable the Gen 4 to literally
unleash horsepower without restrictions.
Sporting the same classic 80mm tips as Gen 3, everything else about
Gen 4 is new. It’s lighter, stronger and more robust – with a
distinct sound unique to the generation.
Does it work? You bet it does. Performance gains of 5-7 peak rear
WHP can be expected. Is it really that free-flowing? Comparison
dyno tests were run on an E46 M3 with no rear exhaust vs one with
the Gen 4 system installed. Zero power loss was measured with the
Gen 4 in place. Like we said, this thing is practically
invisible!
But you can sure hear it. Just listen for the rich, low frequency
tone at idle to moderate RPMs. And the distinct, robust sound at
higher RPMs – validating Gen 4’s superb performance
characteristics.
With its flush aerodynamic fit, high-polish finish and quad 80mm
straight tips, this rig is considered by many enthusiasts to be the
sleekest, most aggressive exhaust around. Installation is simple,
utilizing all the stock mount points with no rear valance mod
required. This product comes complete with full warranty
REDUCED special price while available.
