Extractor mod... Mod or not mod??

[Mroonws]

My original spring rate was 230/40...but saw my friends 230/45, very stiff. i think its better because the 40s is a bit soft. And what kind of up-grade should be done? Changing the whole interior?

[Speedworksjb]

bro, best if you have time to come down to speedworks jb, we are able to do the setting and servicing all here. gimme a call before you come . so i am, able to arrange the work here. best time to come is during the week day as servicing and setting take about 6 or more hours.

Theres 1 in speedworks sg. I saw it b4, its a crome one ...Cost about 100plus

[Koren]

speedworks in sg? where? 100+ seems like a good price.. but chrome is a bit attractive.. i'd rather do without the finishing..

[Mroonws]

Didn't have the actual adddress but its somewhere in the genting lane area. And he only sells spareparts. Think should be like another road after Miki's... gotta check the hotstuffs...

[Koren]

wats the gain for modding the muffler?

 

 

the gain depend on ur mod also....normally between 2-4 bhp....godd ones can give 10-15bhp

some dun even give any gains....btw,4-1 is for high end power...better for manual cars...

 

For Auto cars? 4-2-1 best?

[Speedworksjb]

its not saying for auto or manual good, 4-2-1 is for normally low to mid end and 4-1 for mid to high end power.

mr mark, for the s'pore expressways, will the 4-2-1 be good enuff? cos i stay @ west and travel to town daily, avg 100 kmh.

 

if so, wen i go up north on the ns highway, going at btw 120-150 kmh, how much diff would it be if using the 4-2-1?

 

how much is it for the 4-2-1 n 4-1 for a 1.6l car?

if change silencer too, do u hav the s'pore approved type and how much?

cat muz remain orig??

hi mark, juz a joke - if u follow the marks & spenser advertisments

 

 

if so, wen i go up north on the ns highway, going at btw 120-150 kmh, how much diff would it be if using the 4-2-1? <--- wat different do you mean?

 

sorry, maybe i did not word it properly - using orig pipes, say 5k rpm at x kmh, wat bout using the 4-2-1, since it helps in the lower-mid range, but now at high range, will the rpm be higher to reach the said x kmh? would it b like the tyre theory, bigger tyres but top speed suffers?

 

will pm u the rest

 

thks
