Stock Exhaust Crushed from Factory
Just picked up a 2018 ZX14R SE. Bar risers, saddleman seat and Brock's Alien Head slip on installed.
When I removed the stock exhaust I was surprised to find both muffler link pipes crushed in. This of course would cut down on power. There is no way this happened during install. The defective parts were installed as is and since the crush is on the inside, it passed right by any inspectors.
Great bike but thumbs down on Kawasaki quality control. Here are a few pics
