Mark does Go have a muffled of quiet pipe??Hi Steve, Mark Sholund has said that the Go engine pipe that I sell has worked really well for him on his CMB Valvoa (sp?) They are $45.50 shipped.

NAMBA does have a noise restriction. Forget what exactly the DB limit is but it is in the rulebook and it can be lower than that depending on the club.The noise restriction is not in place for the 20 size classes in IMPBA. I do not know about NAMBA.
Mark
For Sanctioned Races do you really need a muffled pipe, I think its under the noise limit. At least for now!!
The new 21 CMB pipe works great.

I just like to keep my boats as quite as I can.The noise restriction is not in place for the 20 size classes in IMPBA. I do not know about NAMBA.

Per IMPBA rulebook Technical Standards section K-3 there are NO exemptions for any engine sizeThe noise restriction is not in place for the 20 size classes in IMPBA. I do not know about NAMBA.

Well every place I have raced has never enforced it on the B (.21) classes.Per IMPBA rulebook Technical Standards section K-3 there are NO exemptions for any engine sizeThe noise restriction is not in place for the 20 size classes in IMPBA. I do not know about NAMBA.

All classes have the db limit,the 20 size boats most of the time will make it but not always.The noise restriction is not in place for the 20 size classes in IMPBA. I do not know about NAMBA.
