This is my DC2's Exhaust System.
J's Racing 4-2-1 Exhaust Manifold. ($900)
Quote:
J's Racing 4-2-1 Exhaust Manifold is designed for all around rpm performance and
has been specifically developed for daily driven cars and mildly tuned engines.
The Response Header features a 4-2-1 design for optimal mid-range power while still providing significant high rpm gains.
In addition, the primary collectors are port matched to the cylinder head's exhaust ports to maximize smooth exhaust flow.
Consequently, the J's Racing 4-2-1 Exhaust Manifold offers improved engine response and a dyno proven 10+hp to the wheels.
J's Racing 4-2-1 Exhaust Manifolds are hand made from 100% SUS304 aircraft grade stainless steel and feature TIG welded construction.
Due to the 4-2-1 design, the J's Racing 4-2-1 Exhaust Manifold has no ground clearance issues.
A 2.5" collector is included with the Exhaust Manifold.

T1R Racing Convertor ($150)
Quote:
For maxiumum exhaust flow and power gain,
the stock catalytic converter must be replaced with a free flowing test pipe.
T1R offers the Racing Converter, a high flowing resonated test pipe, for this purpose.
Unlike most test pipes which are simply straight pipes and increase exhaust noise significantly,
the Racing Converter is fully resonated to reduce sound levels.
It is a fully plug and play unit; it is a direct fit replacement and comes with all the necessary sensor holes.
When installed in conjuction with header and exhaust, 3-5whp gain can be expected.
Like all T1R exhaust products, the Racing Converter is made from
SUS304 aircraft grade stainless steel and features TIG welded construction.
Recommended for track and race use only.

MUGEN POWER /// Twin Loop Silencer Cat Back Exhaust System ($1800)

Quote:
Silencing characteristics and the quest for exhaust efficiency:
the two requirements imposed on exhaust systems have a contrary relationship,
and in practice it is extremely difficult to achieve both.
At Mugen, we have continued to employ the straight configuration,
with the design philosophy that low exhaust pressure must be provided,
and that reducing exhaust resistance is an important part of the ideal exhaust system.
The straight configuration is widely used in racing,
and is ideal because, as the name suggests, it provides low exhaust resistance.
However, large silencers are generally required,
as there may be problems with mid to low frequency band silencing and scattering of sound absorbing material
such as glass wool with the straight configuration.
15+whp should be expected
