I may be able to talk my buddy into swapping my FMF for his led but his silencer is really quiet and Idk if I want it quiet, can my power core be rigged to the led? Or should I just stick with the whole setup?
id swap the 2 and check the packing in the LED/LRD if you catch my drift. arnold their great pipes any would be much better suited for your porting you just did as you already suspect and yes awk you'll propable lose some if any performance if you take out/put in a little less of some new packing than required to make it a touch louder.
