Hi, I have a Leo Vince X3 on my 2000 WR400 and when I repacked it I noticed that it has a baffle in the middle of the inner perforated pipe. What will be the result if I drill couple of holes in that baffle? Will I gain power or just ruin the expensive Leo Vince? Will I damage the engine if I do that? I know it's popular to do it on a stock muffler but have anyone done that on an aftermarket exhaust? Thanks!
