| RPI's GT axle back system for
the E92M3 BMWs are unique and unlike any other exhaust system. With maximum
velocity in mind, our GT system uses a reduction method to maintain
exhaust gas temperatures towards the rear of the exhaust system. This
allows for significant HP and TQ gains throughout the entire power band
during the dyno tests.
Like all RPi exhaust systems, each comes
with a limited lifetime warranty and is 100% made in the United States.
All
RPI Exhaust are made in the USA, and ships in 1-2 business days.
In
rare cases where a unit must be built, please allow approx. 1 week for
production.
