I just bought a used z125 and it has a zoom exhaust with the little stubbie can and fairly straight header. I noticed that they also make a loop system similar to the yoshi and it sports a longer muffler. Has anyone made a direct comparison of the two? Will the loop give more torque? Will it be quieter do to it's longer header and muffler? My exhaust is not too loud unless I remove the baffle thats located between the header and muffler but it is a lot louder without the baffle but sounds meaner. I may just buy the loop system,make the comparison and the sell the other. Any thoughts?
