These systems utilize the stock header assembly. Bolt on and slip-ons replace the stock restricted muffler resulting in better sound and an increase in power.
Dual Retro Drag Slip-Ons in Black.
M4 Performance Exhaust engineered the Retro Drag dual slip on exhaust system to offer an original exhaust that provides performance increase along with the obvious sick looks with the black ceramic coating.
The look of the M4 Retro Drag dual exhaust is not the only thing separating it from the others, the sound produced from this exhaust announces the pure power the ZX-14 is known for.
Replacing your stock mufflers with the Retro Drag cans will lighten your load by up to 21.5 pounds thanks to M4's diet plan of using cutting out unnecessary materials.
Stage 2 quiet insert is optional (Sold separately).

But can you guarantee they will fit the Australian model. as they tell me when ordering for Australia you need to order European parts? do you know if this is correct. and how long do you think postage would take?
