Hey guys, Throwing around the idea of putting a few extra holes in the tail pipes of my ZL (between 2 and 4 holes in each muffler) to add some extra sound without replacing cans, rejetting and all that good stuff. So a few things: Do you guys think that by adding a few holes to increase the flow some with stock airbox/filter that I can get away without rejetting? Has anyone done the same on their ZL600 that they can recommend drill sizes, number of holes, advice? In addition, if anyone has done this, how does it sound? Worth it or no?
