RC BOAT EXHAUSTS RC BOAT EXHAUSTS
 

The development of petrol engined radio controlled boats has come a long way in the last few years. This has enabled manufacturers to build larger more dynamic race boats that are a pleasure to operate and setup.

Coker Race Products have developed performance exhaust systems for the Gas Tunnel Hulls, Cats and V-Bottoms.

Coker Race Products also do performance modifications to the Zenoah engines.

 
 

The CRP 26cc Zenoah Outboard Exhaust developed for the Gas Tunnel Hulls.

This Exhaust is a simple bolt on and go, giving perfect throttling and ease of setup.

 

 
 
The CRP outboard exhaust is designed to create strong acceleration without the loss of good throttling characteristics. This exhaust system is in its fourth year of development and the results out on the water show this. Because of the multi taper design, we have been able to eliminate the exhaust water cooling that so many others use. Straight taper header pipes hold heat and slow heat dissipation in the exhaust. The balance of the boat is also not compromised because of the rap-around design and the careful attention to weight distribution. The hydroforming process used to manufacture this exhaust system allows for strengthening, allowing Coker Race Products to produce a light, yet very strong exhaust system that is resistant to cracking. The use of high grade materials like KCR1, eliminate hard and soft spots (stretch graining) in the system that come from work hardening when forming. This exhaust is available with either a Aluminum or Carbon Fiber Silencer.
 
 

The CRP Venturie Stinger 26cc Zenoah Cat Exhaust.

Designed to work "without exhaust water cooling".

Utilizing the CRP Venturie Stinger.

 
 
The new CRP Venturie Stinger CAT Exhaust takes RC boat exhaust development to the next level. Labelled it's the "PIPE" because of the perfect performance with a standard out the box CAT and Zenoah engine. This setup will blow your mind. Again development is aimed to create perfect throttle control, a perfectally balanced boat and the latest exhaust technology. No watercooling for the pipe. The mount point has been positioned to eliminate the resonance that causes exhaust breakage and vibration through the boat. The venturie stinger helps keep the exhaust gas temperature at the correct level, without affecting the combustion temperature. The faster evacuation of hot exhaust gasses allows you to achieve this. This exhaust is available with either a Aluminum or Carbon Fiber Silencer.

The CRP Venturie Stinger 26cc Zenoah V-Bottom Exhaust.

Designed to work "without exhaust water cooling".

Utilizing the CRP Venturie Stinger.

 
 
The new CRP Venturie Stinger V-Bottom Exhaust is designed specifically for the V-Bottom boats. With many of the performance design features of the CRP Venturie Stinger CAT Exhaust. Again the design and layout is specific for the V-Bottom boat, moving the center of gravity back towards the center to create a system that balances the weight across the mid to rear of the boat. Designed to work without exhaust water cooling. Utilizing the latest in exhaust design technology. The multi taper header and diffuser sections of the exhaust allow the accuracy of throttling control to be manipulated without affecting peak HP and the multi taper baffle cone and venturie stinger allow for the Torque and HP curve to be manipulated in the area where the engine starts to accelerate. Hydroforming is the key to the strength of this exhaust system, allowing for light weight to create the correct resonance in the exhaust. This exhaust is available with either a Aluminum or Carbon Fiber Silencer.
