I had the headers off recently to polish them. Thought I might have not put em back on right. Pulled the headers and they were right. Pulled the indicator to see if it wasn't sagging excessively. Nup. Tailpiece and rack off looking for bent subframe. Footpeg bracket swapped between the bikes to look for bends. Mounts for this on frame ok. Shit.
Anywho got three spare stock pipes- all off 08 models. ZRX has an 05 model pipe on it and it is identical. 01 model however has a shorter pipe- nuffin wrong with 08. Wasted way too much time working that out. Shit.
