just buy the rksport cat back and an two piece obx header do i need anything else or can i just connet everything to the remaining converter. Thank alot.
The header will have to be welded to your converter. You'll probably have to do some cutting of the stock pipe to get them together. Make sure you have a new exhaust manifold gasket identical to the stock one, if the header came with one, do not use it. Make sure you can make a trip to the auto parts store in another car if either of your O2 sensors gets damaged while removing them from the stock exhaust bungs. They tend not to be very cooperative when removing them from the stock piping.
If you can weld, then you can do everything yourself. If you can't weld yourself, invest in a U-clamp or a nice band-clamp ot hold the converter and the header's collector pipe together while you drive to an exhaust shop to get it welded.
The cat-back system should bolt right up to the stock converter's flange, as usual. Make sure you use a new 2.25" collector gasket when joining the flanges. As far as hangars for that system, RK Sport's instructions should be helpful for that.
