i was thinking about getting a 3" magnaflow with some JBA titanium ceramic coated headers.... would that make an annoying drone or would that sound nice?... thnks in advance! i have an 07 supercrew... 5.4L
edit** i was also gunna put the 77series K&N intake and try to fit a TBS on ther as well (if they actually increase hp and my milage lol)

 

get the K&N FIPK2 intake kit instead. it uses a larger tube then the 77 series, and provides better power gains. plus it sounds mean.

 

thanks man... ill definatly go after that

 

im trying to achieve better gas mileage.... not necessarily power... what would be a good setup for that?

 

most people gain nothing from adding shorty headers, I recomend you save your $$ for some long tubes

 

sweet... u jus saved me like 500 un-necessary bucks lol

 

talk to built5.4 he's tried (just about everything) everything on his truck and he's on exhaust #21 i think
