nitrus said:friends and bros ... i reli reli need help ...
i juz changed to 4-2-1 extractor and replace one thing (look like small-muffler box liddet in the middle underneath my car.. Wats this box ar?), replaced that with a bullet silencer...
then now i noticed my bassy exhaust sound not so loud ady. .. but now it has this sssssssssssssss sound .. like "zzzzzzzzzzz" kind of sound .. quite annoying la ... only when my car moving will have this sound, why ar? If my car not moving and i Rev, dun have that "zzzzzzzzzzzzz" sound ..
What happened?
I sent back to the shop 1 time last week ask him check, there was a leaking in the pipe near the CAT in front there .. so he weld back ady..
Then after that still got the sound.. send again today he said the sound is from the pineapple (CAT converter) below front there... he say gotta change shorter CAT coz my CAT too long... true ar? my fren said it's not true..
damn annoying la the sound especially when i moving slow and not hi-revving ... like got "zzzzzzzzzzzzzz" when slowly picking up.. :frown:
can anyone help me plzzzz... Or issit normal to have that sound after changing extractor/bullet for my Proton Saga LMST ?
One more thing is, my car idling is at 1000rpm, he say it's quite high. should lower... if not waste fuel and dunno wat .. Next time service shud i ask Proton service lower the idling timing abit ?
sigh.. i hate problems... :help:
gavan said:eh, aint the pineapple the flexible arrr si foo cookie?? if it is? why got sound wan if its too long??
wait wait, bro, your car got CAT ar????? thought yours is a carbie? got CAT wan meh? but anyhow, its kinda normal lar if you had just only remove the centre bullet but still is using the original muffler, cause my colleuges car sounds the same, he removed the centre mid box on his waja...so his car when start also got this "zzzzzzz" sound, alternatively, please check to make sure your piping isnt touching or near any metal parts as when the pipe vibrates, the thing will produce funny sounds if touching metal, you know, metal against metal, soft touch sometimes is "zzzz" mar instead of "kok kok kok"
yea i removed the center one box thing underneath ..replace with a bullet .. 
nitrus said:cookie: i dun think its leaking, coz i went back ady one time before this and they fixed a small leaking..
anyway, the pineapple thing is not the "jagung" looking thing below my gearbox there meh? that isnt the CAT...? :hmmmm:
