TORQUE & RESPONSE
The unique design incorporates VORTEX MECHANICS, which sets up a spin effect
within the exhaust system DRAWING THE GASES AWAY FROM YOUR
ENGINE creating true TURBINE EFFECT.
* Creating more TORQUE and much LESS FUEL CONSUMPTION
Typically. Land Rover V8 From I9 Ltrs. per 100km - TO - 13 Ltrs. per 1OOkm.
* STREAMLINE DESIGN allows easy gas flow with LOW TURBULANCE.
Better heat dissipation and no water catchment areas ensuring minimal
corrosion and very long life.
* The VORTEX created in the exhaust system evacuates the combustion chamber
more efficiently to a POINT OF VACUUM on most vehicles allowing the engine
to rev freely.
ROCKET POWER MUFFLERS - MORE THAN A MUFFLER
HOW THE MUFFLER CAME ABOUT. - by Brian Will
We have always been interested in engine and car performance to enhance our drag racing capability
when it was 1/8 mile & then rally track driving. While I was setting up Engine performance, 1 always
found exhaust systems to be of vital importance. e.g. low down power, or top end revs needed different
size & length systems. Street cars with straight through mufflers had top end power & rev's,
while hollow boxes with offset pipes, had low down power & no revs. These were some of the options
available in sports style mufflers, which to my mind were inadequate.
After some years in the automotive game and considerable experience with exhaust systems,
I decided there must be a better way.
First we needed a muffler without square colliers inside so that moisture and pollutants would
Secondly we didn't want exhaust gases to reverse flow causing turbulence & creating unnecessary
So eventually the Rocket Power concept was born with its unique solid tubular construction
and special conical ends The inner cylinder has domed ends which absorb the gas pulses and
deflects the air flow through the swirl tubes.The SWIRL TUBES rotate the exhaust gases into
a powerful VORTEX.
Thus the name TURBINE EXHAUST SYSTEM. The gas vortex generates a gas flow from the
combustion chamber through a suction process, rather than a back-pressure process.
The end result is a brand new Technology in exhaust muffler systems providing
excellent low-end torque & snappy throttle response due to the streamline flow design.
In most cases simply replace the standard muffler in the standard position.Preferred place
is situated before the diff, which also ensures sufficient heat to dry the muffler from moisture.
It is recommended to install a resonator before the muffler or at the rear, if this is not possible.
( RPM resonators are available from this Shopping Trolley )
The Muffler has a nice sounding note a little like the PORSCHE. I suggest that in some V8's,
especially short wheel base vehicles. install the DOUBLE INSULATED RPM MUFFLER to
ensure the noise level is well down.
The RPM Muffler EXHAUST EXTRACTOR system can be fitted to most PETROL - GAS
AND DIESEL ENGINES. In fact we have had superb results with diesels in the 4-wheel drive
market but there is an untapped market for tractors and earth moving machinery where pulling
power is premium. We are looking forward to breaking into this market, as the results are likely
to be quite remarkable based on all the data and experience that we have gained so far.
Rocket Power Mufflers - Testamonials
1. Holden Commodore 1985, VK, 5 litre V8 Engine is warmed up a little. Has extractors
going into 2.5 inch single pipe then into a Rocket Power Muffler. RPM fitted February 1996.
Increased 7 bhp at rear wheels. Sounded very good, nice deep note, excellent power and pick up.
Kym was very happy.
2. Holden Commodore 1991, VN, V6 Engine always pinged under load but when a
Rocket Power Muffler was fitted the pinging disappeared and the exhaust colour went from
black to grey.
3. Holden Commodore 1987, VL, 3 litre V6 Replaced main muffler with a 2 inch
Rocket Power Muffler. Good power increase, nice sound, fuel savings of approximately
15 to 20 %. Graham was pleased.
4. Ford Fairmont 1972, XA, V8, auto Replaced standard muffler with 2 inch Rocket
Power Muffler. Sounded good, more power, smoother gear change and 15% less fuel consumed.
5.Toyota Landcruiser, 3.5 litre diesel Has extractors leading into a 2 1/2 inch system
with a Walker super turbo muffler. Once the muffler was replaced with a Rocket Power Muffler
the car has a great exhaust note, more power low down and reaches maximum revs quicker.
Experienced 15% fuel savings.
6. Ford Falcon Station Wagon, ED, 4 litre 6 cylinder motor. Once the standard
muffler was replaced with a Rocket Power Muffler the exhaust note measured 82 decibels
which was the same as the standard muffler. Fuel efficiency increased by 5 mpg on trips.
The power button is not used any more.
7. Mitsubishi Electroserve L 300 van, 2 litre 4 cylinder motor, auto. The van is
on LP gas and is always loaded with batteries and tools. After fitting a 2 inch Rocket ower Muffler
the van received a big increase in torque and revs. The van is going faster on the same gas mileage.
8. Ford Falcon, XC, 4.9 litre V8, auto sedan After the standard muffler was replaced
with a Rocket Power Muffler the car had a nice clear V8 sound. The throttler response was
amazing as it only required 1/2 the throttle position to maintain the same cruising speed. It felt
like the car was going down hill all the time.
9. Holden Calais, 5 litre V8, The standard exhaust system was replaced with a set of
Genie extractors with two 2 inch pipes leading into one 2 1/2 inch pipe and then into a Rocket
Power Muffler and resonator. The car received a big increase in power and around town the
mileage increased from320 km per tank of fuel to 410 kms. His friends thought he had the motor
10. Mitsubishi Sigma, 2.6 litre 4 cylinder, sedan After the standard muffler was replaced
with a Rocket Power Muffler the exhaust note changed to a nice note, the power increased
and 15% savings on fuel consumption.
11. Holden Torana, UC, 4.2 litre V8, sedan. Craig Walkom fitted a 2 1/4 inch
Rocket Power Muffler to his car in October 1995. In November that year he reported
that with the car running a rich mixture it does a tanding quarter mile in 14.06 seconds
achieves 28 1/2 mpg and up to 32 mpg on the highway.
12. Volvo, 2.4 litre fuel injected 4 cylinder station wagon. With the standard
muffler the car would complete 380 km on a full tank of fuel during short runs. After
fitting a Rocket Power Muffler the fuel mileage increased to 450 kms and had more
torque for easier passing.
13. Ford Bronco, 5.8 litre V8, auto The engine has a 1/2 race camshaft and had a
2 1/2 inch sports exhaust. The sports muffler was replaced with a Rocket Power Muffler.
The car was dynoed on the same day and gained 7 bhp on gas and 5.3 bhp on fuel. The RPM
muffler does not give full increase of power until the car has completed 200 to 250 kms.
14. Daihatsu Charade Evolution. 1.3 litre and 1.5 litre motors. Maughan Thiem
tested a number of sports mufflers to try and lift torque at low revs. There was very little
torque below 3,200 rpm but after a Rocket Power Muffler was fitted the torque started at
2,500 rpm. Maughan Thiem was so impressed with the result that RPM mufflers were fitted
to the Evolution Charades as standard equipment.
15. Holden Kingswood, HQ, 5 litre V8 A Mt Barker mechanic handyman buys and
sells cars. In September 1997 he fitted a Rocket Power Muffler to a Holden 5 litre V8
and was happily surprised with the increase in power and the sound and it sold quickly.
He removed a 308 V8 from a U Torana with dual exhaust system and fitted it to an HQ
Holden with a single 2 1/2 inch exhaust and Rocket Power Muffler. He claims
that the HQ has better performance now than the lighter Torana. He highly recommends
the RPM muffler and, has since fitted RPM mufflers to each car he has bought.
16. Holden Utility, HJ, 5 litre V8 The engine has a mild race camshaft with 9.6:1
compression. The Walker Super Turbo was replaced with a Rocket Power Muffler and
a single 2 1/2 inch exhaust System. The ute was dynoed by Road and Track Services and they
recorded an increase in Brake Horse Power from 229 to 235 at 3,500 rpm.
17. Chrysler Valiant, 1974, 5.2 litre V8 After fitting a Rocket Power Muffler the
fuel consumption has increased from 14.5 mpg to 18 mpg. Barry feels the muffler should
be called the 'easy breathing muffler'.
18. Ford Falcon, XD, 4.1 litre 6 cylinder This car has completed 390,000 kms
without any major engine overhauls. The dyno tune tests show an increase of 3 kW from
62 to 65 at 100 kph after fitting a Rocket Power Muffler. Ray is very pleased with the
increase on performance and excellent fuel economy. Ray regularly travelled on a 137 km
trip every week which cost him $23 in fuel. After fitting the muffler his fuel
bill reduced to $13.
19. Ford Courier diesel utility, 1985, 2.2 litre 4 cylinder Low end torque has
improved so that he now crests a familiar hill at 80 kph which is an increase of 10 kph.
Fuel economy has increased by 10%.20. Kawasaki ZX6, 1996, 600cc, 4 cylinder 4 stroke
This bike has been used for racing with a straight through exhaust system tuned on a bike dyno
(Dynojet model 150). After fitting the bike with a Rocket Power Muffler the brake horse
power increased from 97 to 99 with a higher power curve.
21. MGC GT, 1969, 3 litre 6 cylinder The car was fitted with two hot dog type
mufflers and one was replaced with a Rocket Power Muffler. The car has more low end
torque and revs more easily enabling it to accelerate up hills where it previously had trouble
maintaining the same speed. After a minor tune by the owner fuel economy has increased be 10%.
