exhaust

Many different sport exhaust systems
are offered on the market. The most well
known names are REMUS and
SEBRING.

The products of REMUS and SEBRING
are offered worldwide by many
automotive suppliers, which all claim that their sport exhaust system from REMUS or SEBRING give more horse power and torque. I searched the whole web, butn't couldn't found any facts, reports or diagrams who conform this, neither how the sport exhaust exactly work compared to standard once. Any additional information on this matter is welcome, just send me a mail

The website of REMUS tells us:
Using a special inner construction the backpressure is reduced by 35-85% which generates 3-5% more output and torque. This difference is not only visuable on the measuring-stand, but can also be felt during driving. The special construction also allows a fuel reduction.

The grafic that I have seen show a Golf III VR6, which generates about 4% more horse power around 5500 - 6000 rpm, so that is has 180hp instead of 175hp.

As a diesel engine has not as many torque and horse power in at higher rpm's as in low, it will have a positive effect on the accelaration at higher speeds and the top speed it self.

The manufactor L&W of sport exhausts have a
special inner construction with "inner wholes"
that generates a "turbo" effect and gives
an enormous amount of extra horse
power and torque. Unfortunatly
can't any fact or figures be
found on their page.

Manufactor Ravin uses a
special Z-Wave technology
which has the same
performance effect as the
above mentioned sport
exhausts.

Remus offers also a Z-Flow Metallkat, as replacement
of the standard kemarikkats. Advantages compared to
standards kats are:
- Up 55% lower exhaust
emissions
- Optimizes exhaust flows
- Reduces back pressure
- Increases performance

The Z-FLow is available for VW Golf II & II and Passat and OPEL Kadatt & Astra models. Prices are around Euro 700,--.
