RE: The unofficial Home of all that is Nitro Vee...
I take it that you took the exhaust coupling off there as it is on in the before pics, you may wanna think about a tuned pipe for it, I really like my macs 2.5cc pipe, it was 28 bucks at tower, takes a little work to mount it, you can see how i did mine in the pics i have one here....glad to see at least someone is talking about these boats....
