I finally put the Z on the Dyno. They held it at 6500 rpm for 10 seconds to watch temps and pressures. She smoked a little but HEY, she's got over 150,000 hard miles on her and the rings and valves seals aren't so good any more. http://media.putfile.com/Dyno-Run-6500-RPM Then they did a 6000 RPM hold and HP test. They even recorder it for future referance. The muffler was OFF and brand new pipe, from the header, all the way out the back was bent and installed. Afterwards, A "Raptor muffler was put on. It sound so sweet now. Kinda has that big V8 tinny "flowmaster" sound now. http://media.putfile.com/Dyno-Run-6000-Rpm I'll Have video of the FULL exhaust on the "Putfile" site later on today. Due to "non-disclosure" reasons, I can't tell you why you'll hear these exhaust notes all over the world, until after MAY of this year. It's killing me, not being able to let ya'll in on it but give it a little time. For those of you who think you know why, Keep it to yourself.:classic: Dave. My putfile home page
