The pipe was brought in Luxemburg at the 1/8 EC A this year by EFRA and they should have tested the pipe. Unfortunately the rain came.
The week after the EC one of the engine producers we work for called us to suggest not to spend time on a silenced pipe because he said he was against it and had "big friend" against the new pipes...................
Started to test it on offroad cars because we had many drivers in the category. But EFRA said that the new pipe was only for 1/8 onroad because the problem was there. The results were good but obviously we had to try many solutions. Different shapes and manifold and internals. Substancially it has more volume so that the gas has to make more distance before to coming out.
The first project of this pipe came by a pc-software normally used for motorbike's exhausts. This software said that our engines needed more volume to maximize the performance and this we did. We gave more volume to the pipe without stopping too much the gas' speed.
In the end the pipe had bottom and high power like the nowadays sistems.
The only less was the weight but.... not a problem on the 1/8
...but then came the bad news: EFRA said no new pipes ruling
