dont know about kleeman. wont pay their prices! the c32 headers are the short flange style and the slk32 or srt-6 exhaust flange drops down behind the engine to the exhaust. if you look at the eurocharged site at the c32 header pics then look at yours you will see what i mean.
also there has not been signifcant gains on any short headers and minimal versus the cost on the longtubes
