Strange Popping Noise from My Exhaust

When I step on the accelerator and leg go there is some popping noise. Any idea why is there a popping noise? There is no engine check light though. Did a search on youtube and other Satria Neos that have after market exhaust seems to have this popping noise as well. Is there a defect or something?

Btw, there is quite a bit of smoke as well. No idea why.

Yeah, that sound is good. I like it.
Is there smoke everytime you rev? Or just cold start?

Hi! Its only cold start. No visible smoke after I drive the car for around 20min today.

bro hv ur spark plug checked

bro hv ur spark plug checked

OK Thanks but my plugs are new though. They are only around 1,000KM. Also the sound occurs only after I change exhaust. Stock one no noise at all. Thats why I find it weird.

looks like ur car is normal

white smoke during cold start could be from condensation...signs of a healthy engine

popping sound after change exhaust is also normal... mostly due to unburnt fuel..also normal since car manufacturers tend to set the a/f a lil rich for reliability purposes

Hi Thanks! I believe its due to condensation. Cause right now there is no smoke at all.

if you hate the popping sound, you can get a tuner to use PDT and slightly tune your ecu for a smoother exhaust note.. last time when i went from stock to full hotbits system, it pops like mad and i felt the car loss power when it pops during driving (could just be my feelings).. so anyways i went to my reguler tuner for PDT and it was smooth driving later..

 

[holysniper]

Sorry bro what is PDT? Any 4-2-1 extractor to recommend but still maintaining stock mid n muffler?

 

[reefdee]

PDT is short form for proton diagnostic tool if i'm not mistaken.. its the tool that tuners use to connect to the neo's ECU and adjust some parameters in the ECU.. most branded 4-2-1 extractors are good be it marco, everco, hotbits, powerzone and such but to use those extractors with stock midsection and muffler is a big no unless you dont care how your muffler will sound.. because both the stock midbox and most probably the stock muffler too has no or almost none fiber material, your exhaust note will sound like, how should i say it, empty tin can sound.. it will sound like an old school 2 stroker kapchai.. :)

i would suggest u atleast change your rear muffler with the extractor upgrade and then later add a midbox to reduce the exhaust volume if you find it too loud..

So neo has only 1 cat converter at the extractor? I wanted to change it out as I find it very restrictive and rev climbs very slow.

Or should I change final drive or gear ratio lcp :(

Sounds quite tip top to me. It's like that la exhaust note. I'm not sure why but most exhaust also like that. I'm guessing it's partly due to you suddenly release the gas and that causes a sudden change in exhaust gas velocity. Try you release slowly.

remove catcon, change final drive and lcp all helps acceleration.. but their cost differs..
remove catcon ie install 4-2-1 header will cost u around rm400..
lcp around 400-700 depending on brand..
final drive? this is the most expensive but also give biggest performance increase..
this cost around 2k more or less.. depending on which garage u go to..
