This one...

Sifus,

Need yr advice here. I hv a ten year old Proton car. (fuel injection)

I hv never made any modification to the exhaust pipe. Recently I have changed the mounting bracket for the exhaust pipe as it has wear off.

After ten years, do I need to service my exhaust system ? Is there anything that I need to change as my exhaust pipe is not noisy ?

Do check your exhaust system for any leakage every 2-3 years

If your exhaust with catalytic converter is actually need to be replace after 10 years but we don't really care, so check whether your exhaust system got any leak, else it not necessary to replace beside you have done quite some modification to your engine and need bigger diameter exhaust pipe.

hello all..want to ask..

perodua alza ezi, changed k&n drop in, denso iridium spark plug and a VS installed...for exhaust stil stock..

any recommedation to upgrade performance on pick up and FC ? changed to 4-2-1 extrator?

dear all sifus minta tunjuk ajar

pic1
pic2
how much to change to a new one because it cracked already as you can see in picture
pic3

i visited to 3 shop already and 3 shop told me different story
1st: they called it as manifold and charged RM280 for it <<this one like conning me because he told me the pipe also got leakage but i know it isn't.
2nd: they called it as cat converter and reckon at least RM500
3rd: they only pointed it and asked for RM230

the link is not a virus i can assure you because i cannot put image here using my fb link

no need change. keep stock

Exhaust manifold... looks like a crack in the exhaust manifold at the O2 sensor there (pic3).

You can try ask if the shop can 1) weld back... 2) find halfcut parts/other old manifold from same model... 3) replace new one (dunno if still got stock).... 4) replace with custom made manifold (the most expensive option)

I would recommend option 2.... if you can find the part, maybe get it for a few ringgit... normally when the owner of the same model change to aftermarket custom made exhaust manifold.. the exhaust shop just throw away as scrap metal. Half cut maybe more expensive a bit than getting scrap metal part. But they work the same.

cracked lar boss... keep what stock?

this problem exists long time ago. But recently the foreman which is trust worthy asks me to repair it because the condition is getting worse.. if not makan fuel

hi thank you so much.. but my car is old model city 1998 so i think i only manage to get a half cut one

guys thank you so much you all are great

that looks like an old city... dun even know if can still find any discarded stock manifold or not nowadays..

i second this

personally, as the crack is not significant enough to have leaks, i would leave it alone as it is and *PERHAPS* at the same time find for half cut/replacement (as per bro unitron recommended)

if the crack is serious enough to leak, your exhaust manifold area would be darkened with basically exhaust leaks and it would be very obvious which your pictures did not show.

if you're that worried, consider option 1, weld it for the time being

hi guys wanna ask it is legal to put on 3 inch piping for my car?

the regulations is on noise, not on size... put as big a pipe as you want.

Current car 1.3 manual saga, highway driving and emphasise on rpm 4k and above since travel aroun 120 km/h ++, 4-2-1 extractor better? Exhaust still stock.

ok nice... if i put apexi n1 ok hoh?

@Quazacolt @unitron please give some opinion

i visited to an exhaust shop in batu caves and their consultation

-manifold crack... serious as it is near to engine.. cause power loss+eat oil
-old honda city one the manifold attaches to cat con
-they advice me to remove manifold+cat con and replace with 4-2-1(my car AT gearbox)
-the 4-2-1 is galvanized steel.. nothing special
-siap pasang Rm380, negotiable with the boss

my car all stock, if i chg to 4-2-1 is there any more i need to remove/upgrade as well?
good to remove cat con?

this one?

i've heard many good things from them, however they don't accept credit card so it's a pain to deal with them as they aren't cheap also.

-manifold crack shouldn't eat engine oil (unless you mean petrol)
again, refer our previous replies, chances are exhaust shops just want to scam the shit out of you for business

- yes they just want your business

- no good to remove cat con.

please check your o2 sensors etc properly and/or bring to proper workshop check/diagnose.
