I would really like to see some performance data on the Barrett. I think it looks good from an overall aesthetic point of view, but I am curious about the inlet pipe to the muffler. I noticed how it nozzles down, and that got me thinking. Considering the net positive pressure from the direction of the muffler inlet to the exhaust I think that the exhaust gas speed will increase as it passes by the necked down section immeadiately before the muffler body. OTOH, if the nozzled down pipe just I front of the muffler body increases back pressure, will the system think that there is too much fuel (through the O2 sensor), and lean out the mixture?
