Exhaust system question

OK Jordan i'm using the 2 old pieces of pipe that still out of my engine(on both sides) they go straight down thru the hull about 5 inches, i should cut the pipe to add a 90 degree elbow to the straight pipe to the next set of 90 degree elbows to the muffler? are all the bends and or elbows 90 degrees?, also the straight pipe rail under the hull are in good shape, I bought 4 pipe holders brackets from Brian A. to keep the pipe from falling out., The only thing i'm missing is the 2 circle steel plates that the muffler pipes go into that are attached on the bottom of the hull, I wonder if anyone on this forum has any spares of these circle steel plates? thanks Jordan , i won't use the flex pipe, I will get pics soon, to help in my description. Cheers
