I was wondering if anyone could give me any tips before i go drilling any holes in my boat. I just purchased a set of hardin marine 45 degree side exit tips. Is there any special way i should go about drilling the holes and, what would i use to cap off the exsisiting exhaust. I am not using diviters so I am just using exhaust hose to connect to the tips. My motor is a 350 mag mpi, also should I expect any gains in mph?

Love my side dumps in my Velocity. Due to the way the noise law was written in NV, they have to measure 1 meter from the transom, that dropped the noise to less than 85db, at the side they were over 94db.

I never thought of that (side exit exhaust) to combat noise regulations. What about if you ran one to each side? I would think that would help with both the stationary idle test and the running test...
