piping get 2.5"
i had 2.5" be4 and now using the stock 2.25" piping catback and i can feel that the car doesnt rev as freely as before.
with headers generally its 4-2-1 for better bottom to mid end power and 4-1 for mid to high end power.
the jdm 4-1 headerS are ok. i currently have these on the itr, but honestly cant really feel much difference.

yeh 2.5" for sure
if you like to rev alot go for 4-1
they only offer a margine of about 1-2 hp at redline over 4-2-1 but still 2hp is 2hp

old exhaust too loud <---- haha
Hey fai jai get a twinloop. It fixed the loud noise in my exhaust, more than halved the noise with only 1 reasonator, whereas i had 2 reasonators and it was still twice as loud! Best thing i ever found. I got mine from EgSI in the trader's forum. Now the car is only slightly louder than stock unless i rev it hard!
no more dronning hwy runs
Back to the question, i'd recommend the JDM 4-1 i just got a set and they really make a difference. If you lucky you'll get the bottom heat shield also!
