I have a completely stock 1998 Summit X and I just picked up a used set of of SLP twin pipes off a 1999 Summit X for cheap. Does anyone have any good or bad feedback regarding these pipes? Should I even bother putting them on? I was wondering if someone is familiar with the kind of power increase I should see. Besides jetting is there anything else I should do when switching to twin pipes? My jets are a 350 and a 340. What size should I change to or is it just a madder of testing with different ones?(mainly riding in Edmonton area)? Any info would be a great help. Thanks
