Hello guys,
need a help!!
Problem 1:
I have installed 3 cylinder muffler on my fz16 with active cat-con. The issue I'm facing is during drop of throttle, there is a light poping sound. Also the out going fumes/burnt gas is not equally balanced on all cylinders (refer to the attached picture). Bike performance is much smoother and barely any raise in sound, although it gives heavy bass note(better than stock one). I had done this modification to enhance the pickup as greater amount of burnt gas can exit during throttling (have widened the output mouth of cat-con by 1/2 inch with two cylinders attached together to the main outgoing muffler as branching unit). The top most cylinder exhales the burnt gas, rest of two just blow cold air.
Can some body help me, how to balance the equal distribution of burnt gas among all the three cylinders and stop the poping sound as well.

Problem 2:
I have installed 5 aux led lights; 2 red blinking break 5W led lights at rear, two 20W white spread led light near head light and one 15W long distance task led light on handle bar. apart from this the main headlight (bajaj avenger make) is equiped with 35W led light and audi type strip led for parking light. I have done this work to travel long distance in dark. My question is should I replace my battery with higher capacity or the stock one will suffice the current installation if run all at the time. (refer attached picture)

All the modification done on my bike are street legal, if not then can i get it endorsed?

Please advice..
