caaaannn..wei apa lu dah bikin kat kereta? LCP sudah ah?

if u after a wide powerband:
what about readjust collector length to tune at 4k - 4.5k rpm to raise the torque dip and adjust pipe size so it still maintain high flow velocity at 3k rpm?
if u after for best power:
tune length at 5k u will get high boost when u reach max torque, the dyno curve will form a steeper hill, have to change gear often to stay "tuned" but peak power is increased
small pipe needs throttle control for pickup, big pipe can floor the pedal for instant response
my humble opinion only hehe
i 2nd that, u are indeed a wise person to kitai back the exhaust guy hehe
wide powerband is my main aim now... coz when tested actual run, when enterin 4th gear at 4k rpm (3rd gear at 5.5k rpm), d accelaration is abit stagnant..what about readjust collector length to tune at 4k - 4.5k rpm to raise the torque dip and adjust pipe size so it still maintain high flow velocity at 3k rpm?

not sure d exhaust workshop able to do dat or not oo... coz change bullet location, n need add abit pipe back...
dats y i thought easier jus change d whole piping to 1.6".. by changing it also, m gettin more hp for rpm more than 4.5k rpm..IF all makes d 3k rpm really sucks, mayb i opt to change longer intake runner to tune it at 3k rpm..

Guys...hope i change my bullet to 1.6'' according same diameter as piping...in n out...hope powerband will b bck....
by changing d swirl type to normal bullet will do... for placement, can ask mfa... or any workshop dat know wat they doin..
