EFRA Homologated muffler list |
| The EFRA homologation Officer released the list for 2011 |
| Enclosed the updated muffler/INS list for the 2011 season. On the list is 1 special muffler from Hipex which is
the first low noise muffler. It was just send to us before the deadline and I still need some track time to see how it performs. Noise level is about -3/-4 dBs less. I am also busy with testing extra silincing units which can be mount straight onto the majority of the existing mufflers. This could be very helpful as a solution and also gives some time to sell out the stock of mufflers that is with the drivers, in the shops and at the manufacturers. The level for noise reduction with such an extra unit is around -4 dBs. I hope to give you some more information in May after some more track testing. The list:  |
