I am sure Bob could have worked out the dip with further changesespecially altering the timing. Its hard saying when your not sure what has been done. You are right though the pipes were made for higher output engines and the Preds were made for stocker set up. I know Bob was busy and had to get the bike done and since Larry was switching to the Carpenter pipe there was no reason to play with a pipe that will not be built again. Larry's had the ceramic coating peeling off, So di Stew Pred. Mine held up so far but the Heat shield brackets welded to the header pipe are not that good. I lost one on each header. Add a rattle sound to the pipe
Massive Torque down low is alright if your pulling a haywagon or 3 bottom plow. But top end is what will win the race even if its on the street. And well we all know these beast have plenty of torque as it is stock.
