i'm about to install a catted x-pipe and shorty headers to my car this week (it already has the cat-back), so i was wondering if i should invest in a fuel pressure regulator and crank up my fuel pressure so the car won't run lean with the new exhaust??? i read an article in car craft about headers and exhaust causing lean conditions - which i obviously don't want...so i was wondering what you all thought? is it a good idea? or should i wait for more mods before i bother with it???
~thanks everyone.
btw, if anyone was at the NMRA nationals at Joliet, IL this weekend, let me know...i probably saw ya there!
