2001 boxster S exhaust
Hi, I have installed a set of BB headers for a 2.5 with that cat system and a factory S sport mufler and rased fuel pressure about .3 bar. The dyno gain was 12hp peak and 17hp at 7200 . Note, I did have to extend the wires for the O2 sensors . The sound is very good , I enjoy driving my S with this setup.
