headers for 2001 boxster?
Can anyone give me the real mail on headers for my 2001 2.7l? I've read a lot of stuff on the 'net' etc and I can't decide if i should outlay the dollars for an increase in HP that is questionable? Can fitting headers increase HP at the wheels of 10 to 20HP (quoted in some ads). If I fit headers should I then fit a full sports exhaust including cats and muffler to gain the maximum or can I just leave the exhaust standard? Will the fitting of the headers cause any problems such as CEL etc? I would appreciate any help with this.
Regards
