idk if i should get the 86-88 RX7 Coupe Non-Turbo Catalytic Converter Replacement Pipe with Presilencer*or the 86-92 RX7 Non-Turbo Streetable Header/Collector. need some rotarian advice. what would give me better overall performance. the header is about 190 and the replacement pipe with pre is about 250.



thanks trent

Just get the cat replacment pipe and pre silencer. If you got the header, you would still have to fab up a "cat replacement pipe. Plus, NA rotaries are loud as hell with a header.
