Solution for B&B Exhaust Drone? - ZR-1 Net Registry Forums

Just a long term update. Last year the DynoMax muffs had pretty much become a boom chamber. We opened one up and the insulation was totally carbonized. This time I decided to go w MagnaFlow muff w almost identical dimensions. Al moved the NPP valves over to these new mufflers and we made one small but I think important change whichis to extend the tips beyond the rear valence panel by ~ .75?. The MagnaFlows are of better construction than the Dyno and w valves closed u get a much mellower exhaust note. Valves open is significantly louder but even then more tolerable than the DynoMax.
I am thinking of trying this next. My gf has pretty sensitive hearing. Anyone have a comment on Block It?
