It seems that more and more tracks have limited the noise to max 100db . With the limited room in a gt40 this is a challenge , at least for me it is. I have made some mufflers just as a test from simple steel sheets I have been able to come close to 100db , but the restriction inside is I belive, way to big . So is there a way to build a silencer that handle 100db with a size one can deal with?
When You see all these new nice gt40s on this forum , with mufflers bougth from shops that sell them . Does they match the noise limit ? or is the noise limit on a track not a issue?
I would like to see pictures of exhaust systems that keep the noise on 100db rpm 4500 and measured three feet from exhaust and 45 deg off.
I use supertrapp without anything to restrict the flow , and the sound is 114 db , and I love it .
But I need to have something else for the track.
I belive that many of you out there have the same challenge.
