If the Swift gearbox is the same as an Esteem's then you can change the final drive ratio.

2) Esteem final drive to be replaced with final drive gear PN 27511-60B01 (79T)
3) Esteem speedometer driven gear to be replaced with speedometer gear PN 23131 - 64B00 (16T)
With this you will get a final drive ratio of 4.388:1 which is the one used in the old Esteem/1000...The stock MPFI doesnt rev beyond 5000 RPM in 4th and 4000 RPM in 5th...by doing this mod alone you will rev higher in the higher gears, thus increasing your top speed, and also get more acceleration in the lower gears...
If you want even more acceleration AND top speed use 165/65R13 (Indica V2 OE fitment) tyres.
Only after doing this you should go for headers and freeflow because you will lose some low-end torque, but it will be compensated by final drive...If you don't want to invest in a full header, just change the 2 into 1 downpipe...you need to lengthen it by some and use a larger diameter pipe for it to have a effect in the usable rev-range...keep the cat and go for a straight-through glasspack muffler...I can't give you specifics for this mod because I have not tried it on an Esteem.

If its not the same box and the final drive is already in the range of ~4.2 - 4.4, then headers and freeflow need to be matched to lower rpm band.
See if you can get a remap that improves low-end.
If you go for a tyre that has more dia than your present one then you could lose some low-end although not very significantly.
