Dinan is the most advanced research company in the BMW
aftermarket. Winning back-to-back-to-back Rolex Series Daytona
Prototype racing championships in 2010, 2011 & 2012 along with
the top two podium spots in 2011 and winning in 2013 the grueling

You can rest assured that you are purchasing the most leading edge
technology on the market. Who else do you want to tune your BMW if
not the company that beats the competition in power and durability
in the most competitive road racing circuit in the US.
What else would you expect from Dinan but the most
technologically advanced exhaust on the market. The problem with
most performance type exhaust systems is they compromise both flow
and sound quality to try and achieve a balance between the two.
Dinan’s Free Flow Exhaust employs leading edge technology to solve
this problem with advanced features not found in most aftermarket
high performance exhaust systems, including a Helmholtz chamber and
single channel absorption increases flow while reducing unwanted
noise and weight.
The Helmholtz chamber is a resonance cavity that reduces the
drone that most high performance exhausts have at light throttle
cruise. In addition Dinan has a straight through single pipe design
to further reduce noise at light throttle cruise so that it is a
civilized exhaust that you can live with everyday.
The single channel dual exhaust is a full 10 lbs lighter than
the stock BMW part. The Dinan Free Flow Exhaust is a sporty
sounding exhaust at wide open throttle when you want it but also
quite and civilized when you are at light throttle cruise. This is
consistent with Dinan’s core philosophy of "Performance Without
Sacrifice". One of the reasons you purchased your BMW is because of
its level of refinement. You won’t ruin the refined characteristics
of your BMW when you use Dinan performance products. This level of
development takes time and is the reason Dinan is usually not the
first company on the market but you will find it is worth the

Dinan Performance Exhaust FAQ:
Does a louder exhaust make more power?
Not necessarily. A freer flowing exhaust makes more power by
removing friction in the exhaust system but how loud an exhaust is
has to do with how well you absorb the sound as it travels through
the exhaust. You can have a straight through design and maximum
power with today’s technology. It is possible and common for a loud
exhaust to actually make less power than a stock exhaust. The best
exhaust is the one that is the freest flowing and has a noise level
that you enjoy.
What makes an exhaust "hummm" under light
This sound is commonly called "drone". It is caused by resonance in
the exhaust system and can quickly give you a headache. Drone is
the toughest characteristic to remove from an exhaust system. The
use of a "hemholtz" chamber to work as a noise canceling device is
a great option along with the use of butterfly valves when
How are Dinan exhausts made?
All Dinan exhausts are designed and hand built in California at the
Dinan Headquarters. They are welded by hand using precise tools to
ensure perfect fit. All are built from 20 gauge-304 stainless steel
for strength and corrosion resistance.
Does the kind of steel used matter?
Yes. Your car's exhaust is subjected to the elements and other
harsh conditions that occur under a car. The exhaust gets hit with
gravel, salt, water, sand and whatever else is on the road. Using
high quality stainless steel keeps corrosion at bay in this tough
