Has anyone used these mufflers .... I was warned at my last race meeting that the noise meter had logged me at 94.7Dba and our "put your car on the trailer and go home limit" is 95Dba, so I have been researching more efficient mufflers and found these.
Does anyone have experience of a road or dedicated race/track car ??
