You guys that have run TDR water boxes before...are they alot louder than stock? I had that and a Riva Red pipe last year and my ski was pretty loud compared to others. Is the noise primarily from the water box or was it the Riva pipe? It had a nice, quick rev sound, but the decibel level was high. Gonna run a new, limited B-pipe this year. Think it'll sound much diff? There's a couple of loud ski's on our lake from time to time and I'm sure some of the older folks hate the crap out of the racket.
