can any one suggest what can i do for my exhaust(currently driving mivec 1.8)?? sound really loud until i pening after cruising 50++km back home, although i use mid silencer(mid muffler), piping 2.5 " but dunno y no power when mivec on ..... not enough tarik force at all like last time before bot.... is it maybe the exhaust guy do wrong or the mid silencer kacau since i know my air is not smooth, like bike, if press pedal to rev and release, got bob bob sound, air struggle to escape, how about the performance and sound if i change to use 2" direct with s.flow at the end? how can i overcome this?? pls advise

peter..your exhaust setup was from previous BOT system right????


maybe u need to change overal piping size with 2" diameter first and see what' the result....

 

[Newbienissan]

dude,

change to my setting, it cater me very well!

4-2-1 >>> pineapple >>> 2" piping >>> FGK 2.3" inlet midbox >>> 2.5" piping >>> 2.5" inlet S-Flow

engine is 2000cc stage 3 mods. i felt is is good for city driving n highway. most noise level comes from the engine bay not the exhaust. if all window closed, the noise is low below 4000rpm, good for long distance cruise

 

[peterj]

what is pineapple?? sory i m a newbie .... i using 4-2 and the set up is like what i say.. will going to see the exhaust redo today, c can i do something or not....

 

[Newbienissan]

pineapple is actually the flexi pipe connected between 4-2-1 to the short pipe before midbox

 

[peterj]

ooo... i use to call that downpipe ..

 

[Newbienissan]

oooo, haha, my bad....anyway, do try my setup, it works for me well.

 

[peterj]

bro, i have done all redo to make back to mivec n/a , exhaust set up as i say + i added 1 more midbox to reduce noise, but, the pick up is nice from rpm 1k to 4k, more then that is like no force at all... yes , it is true, even with my mivec roaring already my car keep slow and steady even kancil or stock 4g15 can potong me like that if they wan how can this be?? my piston anything already change to n/a (high compression), and service necessary parts, is the engine timing wrong affect this?? or like my mech suspect of, block damaged by previous BOT? need help pls

 

[Newbienissan]

hmmm,
then i think you need to find out whats wrong with the engine liao. anyway mind to show whats your exhaust setup now ?

 

[peterj]

4-2 header with 2.5" piping all the way with 2 mid box and 1 rear s.flow

 

[Newbienissan]
