just finished my new exhaust setup at kweng (wai heng kaki exhaust serdang HQ) not too long ago. fully stainless steel, 4-2-1 extractor, 1.6" piping, 2" oval mid bullet, sflow muffler

My old extractor and it's cover, rusted to hell now, and notice the carbon on the cover? It's leaking D: http://twitpic.com/8oeeis
Old middle silencer versus the new bigger, more quiet center bullet http://twitpic.com/8oef6f
New s flow muffler, bigger and much more heavier than the old muffler http://twitpic.com/8oefij
Here's the old muffler, a lot lighter than the new s flow I'm getting. Piping on galvanized steel, so no rust. http://twitpic.com/8oeg7z
New extractor from the bottom view with flexible pipe attached http://twitpic.com/8oeki1
Hmm the welding on the pipe isn't as clean as the premade parts http://twitpic.com/8oexvu
Same goes for this one http://twitpic.com/8oexyp
How my new exhaust looks like on the "surface" http://twitpic.com/8p226p
Fake twin outlet lol http://twitpic.com/8p22bq

all an all, really damn dirt cheap and cheerful setup for MYR770 lol

Really loving the sflow back pressure/scavenging effect, i can see how this shit can dramatically improve my FC already.
RPM doesnt drop like a rock and i can just let my foot off the accelerator. the car still continues to hold its RPM and speed. which feels amazing LOL

of course, pros and cons, while the low RPM/power band is awesome, my upper power band/top end suffered
torque didnt seem as high as before after the 5k rpm. havent got the chance to fully try it out though.
that, and Malaysian roads' traffic jam, i guess i *CAN* live with some minor setbacks ^^;

oh as for the noise level, from within cabin, A TON quieter lol. and engine vibrations seems lesser maybe cuz the car breathes easier?
from outside especially near the muffler, it seems noisier. i think i can conclude that, the exhaust pitch is lower (more bass/less treble per say)
lower pitched sounds are harder to notice after all, especially within the cabin with more "resistance" from it.

i think my exhaust is pretty "burnt in" now as the entire extractor is brownish/bronze ish in color

but yea, in the future i might be playing a bit more with something like a 4-1 tuned length or something, but thats prolly something in the really distant future
thanks again for the setup

and yea, ah hung is a good mech, the foreign looking workers not so much though
ah hung did the piping bending/cutting/rear trims, basically almost everything while the welding are done by the foreign looking workers

discussed this abit with a few people, they also agreed that its better that way, as welding faults can be fixed easier than piping bending faults

aye thats what sifu told me too so i can ignore the cosmetics on the welding
touch wood no issues in the future
