Took my new, to me 1979 Eliminator 21 Daytona to Bass Lake over weekend, Sunday tried to register boat but did not pass db test. Tested 103
On a 454 w/ 3.5 Indmar exhaust, dry tail pipe. I wasn't going to post this but I did buy 3.5" inline ss silencers from CPperformance , And I recieved a set of 3" silencers.
how many db's will these reduce approximately?
I also have a 1994 21 Daytona but it has Cylone 4" headers , but I believe tail pipes are wet. What's the least expensive fix!
