Two stroke exhaust systems are dynamically very complicated yet also very effective tuning tools to manipulate, adjust and capitalize upon an engine's power characteristics. There are a multitude of variables and their effects on the individual powerband targets to be analyzed and considered. My exhaust system designs start by inputting all the necessary information into a program I wrote to generate a beginning point. This consistently yields something that is close to rendering the desired result and has an excellent record. It is based upon many conventional, time proven mathematical approaches as well as a good amount of empirical adjustments drawn from over twenty years of planning experience and application.
I now further hone the characteristics of all pipe and engine packages by computer simulation. This has shown distinct advantages in selecting minor pipe adjustments to find little extras that formerly were only found with real world dynomometer time. It patterns and graphs particle and pressure wave activity in the conduits of the entire engine assembly enabling an astounding insight into the dynamic functions created.
It also requires more input information from the customer and more time dedicated in the planning process. This increases the cost to customer and somewhat reduces the speed, convenience and volume of designs that can be created in a given period of time. However, volume of work and time in preparation are common prices to pay for quality and are routinely accepted here. It is my view that they are always to the customer's advantage.
Porting arrangement analysis and recommendations are also now available through the input of the below listed information requested by the following two form pages. This is available now after many months of repeated requests by the multitude of webpage visitors. This is offered with the understanding that I will not accept responsibility for the success or failure of the porting arrangement due to someone else's inability to accurately replicate the dimensions rendered. Porting layouts will produce the desired results if imparted by a skilled craftsman. Lack of control over "who does what" is the main reason this was never offered before but there seems to be an overwhelming interest in this service. Therefore, I will supply analysis/alteration information at a cost individually established by project. Please e-mail me with specific requests for a quotation.
PLEASE NOTE that submitting this information for the purpose of designing a custom exhaust system BLUEPRINT will cost $135 and up, pending system complexity. Again, please e-mail for a specific pipe project quotation. You must have a fabricator local to you build the system to specification and fit to your particular vehicle's chassis. Custom fabrication and fitment can ONLY be done here if we have the vehicle in house by prior arrangement and scheduling and at considerable extra cost!
Thank you!
