This is a OEM Honda factory replacement swaybar for RSX 02-06, to be used when you have aftermarket headers. With many popular JDM style headers available for the k-series motor this swaybar is a must have. Some will find that using their factory swaybar will not allow the header to be properly installed. With this swaybar it will allow perfect clearance for those JDM style aftermaket headers. It features a large, exhaust manifold pass through opening, and is compatible with most JDM or non-JDM headers that rub against or make contact the stock sway bar.
