Depends on the road situation. Normally, between 2000-3000 rpm is okay for normal driving.

For racing? Shift right before it bounces off the limiter.

or shift at 1500 rpm kung tipid gas driving. hehe

normal driving: 2K-2.5K RPM
race driving: just before the needle reaches the redline

Kung normal temp na yung engine .. 1.5k rpm

Kung cold pa .. 3k rpm

Kung hataw hataw, before tumapak yung needle sa red line. VTEC ftw.

if I change the exhaust, intake, and headers, will I consume more gas even when daily driving?

nope... it wont...........

Depends on how well or how badly the modifications are done. Ideally, fuel economy will remain the same, but if the car is poorly modified, fuel economy might suffer.

i've experience this...hindi maganda yung pag kakamodify ng SiR ko noon kinuha ko parang bara barang modification... at mataas yung fuel consumption ko every week...binalik ko sa stock yung headers and muffler laki ng natitipid ko...same thing lang din kong maayos yung pagkakamodify...
