So my bike is a XS850, its a Yamaha Triple... I found that a Triumph 900 Header fits however the header is a 3-2, the center pipe is split between the 2 pipes like a Y. Anyway I want to make it into a 3-2-1, I know how I want to do it but my question is on tubing diameter and backpressure...
The collectors from the header are 1.88" (1,7/8) OD... Question is, when I tie those two pipes together what should the diameter of that outlet be? Should it be 2 inches?? Also its very hard finding a muffler for 2 inch... How bad would it be to downsize it to 1.75 before the muffler? I want a reverse cone muffler, with a baffle and packing. I want it loud but not deafening... HELP! I have to order pipes, bends, and a muffler. Just to re-iterate... when putting 2 1.88" pipes in a collector what should the outlet OD be? Bigger, same? What if it was smaller for more muffler options? Thanks guys!!!!
