How can i modify 98 auto 4dr civic lx?

already done intake.

girl doesnt want more noise or lose gas mileage. What cheap mods besides JET computer upgrade can I do?
1 st if you like your gas mileage then invest in a quiet catback system, it improves gas mileage

2nd if your thinking of getting a ECU upgrade I can garuantee it'll suck the gas right outta ya tank.

keep everything stock - throw in a b18c5 and get some toda cams and engine work - just leave the exhaust system (header, cat, muffler) stock
