Remus has just released their state of the
art axle back exhaust system for the Z4 30i and 35i E89. Remus has
built and designed this exhaust system from the ground up, addressing
all aspects to make sure this exhaust allows the E89 Z4 to breath as
deeply as possible. Built using 304
mandrel bent stainless steel tubing for maximum durability
and exhaust flow. This Remus axle back exhaust is designed using
OEM specs, so no need to worry about fitment issues, or any
modifications. This system is direct bolt on power for your e89
Z4. Remus has dyno proven this system to gain anywhere from
6-10 rear wheel horsepower. With Remus's patented exhaust and
muffler design, this axle back system gives off a unique
DEEP throaty exhaust note. Do
not wait any longer, be the first to run Remus's all new axle back
exhaust system on your E89 Z4.
Remus Exhausts reduce engine heat and
backpressure and improve exhaust scavenging from the combustion chamber.
They also minimize the power robbing effects of the OEM system to
restore torque and horsepower to the engine.
Problem 1: Backpressure is a typical
feature of an exhaust system. The backpressure on the exhaust flow can
help to reduce sound, but at the same time, it limits engine power.
This power reduction comes from an inefficient burn in the
combustion chamber where spent exhaust gasses are backed-up into the
combustion chamber and contaminate the next burn cycle.
Problem 2: A second problem associated with backpressure
is heat build-up. This occurs in the OEM style chamber muffler.
Hot exhaust gasses are forced through louvers and into dead-end
chambers. The heat builds up in the muffler and then backs itself up
through the entire exhaust system to the exhaust manifold and engine.
This heat retention causes damage to the muffler as well as the
catalytic converter, the system tubing, the manifold and gaskets. Even
ignition wires can burn up due to an overheated, inefficient
How do Remus
Exhausts Solve the Problems of Backpressure?
Eisenmann reduces the backpressure while maintaining a
rich powerful performance tone. Annoying exhaust
frequencies are dampened with a dense wall of acoustical absorbing
material. The straight-through design prevents excessive heat retention
allowing the entire system to run cooler and last longer.
