soulfly: howie has done a lot on his car , i guess he wont be selling that car but only buy a new car...his kancil is a rare species with self-tuned ICE system...hehe:) maybe gf drives that kancil and he buy a monster car

I change my exhaust system.
However still feel low pick-up power.
So I wanted to change the air filter to improve performance.
Any idea?
My car is 1.5 Wira manual.
4-2-1 ext with midbox,1.7" piping and straight-muffler.
Pls advice!

Any good mod for stock muffler (Saga LMST 2004 model), not that much expensive~
thanks
The stock one is very very bising like hell when going high rev.

While that may be true in many cases, there are reputable shops (not tuners) who do quality replications of tuned extractors ie. Mugen, Spoon, TRD, etc .... what consumers have to know is how to differentiate it and know that what they are buying is not a replica of their stock extractor.

Question:
i)What are the benefits of a "swirling" type bullet
ii) Why are there "longer" and "shorter" swirling bullet?

Currently I already have a MUGEN Twin Loop exhaust (and mine is not VTEC engine) on my 1.3L with stock piping and stock center box.I find the twin loop did improve my low-end torque until 4000RPM but after that, the engine struggles to meet the 6000RPM. Sometimes it will be stuck at 5500RPM for a long time.

So the exhaust "specialist" suggested I get the "swirling" bullet compared to normal "RM 90" bullets, apart from enlargeing the pipe.

I m driving swift sport auto..thinking of changing the exhaust...any recomment?price n brand?

you don't get power by just adding bullet or midbox. adding bullet or midbox and its placement only affect the power curve. no matter how you look at it, bullet/resonators/mufflers give some kind of restriction to the exhaust flow.

remember, real max power comes from the header design and a proper piping setup. bullets/resonator box/muffler are just there to suppress noise.

my car setup currently is
3-1 extractor
flexible pipe(2")
stock bullet (1.5")
fake apexi S-flow muffler (2")

piping from extractor to stock bullet is 1.6"
piping from stock bullet till the end is 1.5" (stock piping)

wat i facing is RM50 for my viva
always be on MRR2 from kepong to setapak..
80-100 km/h , normally not over 3k rpm..
i only can get 330km for rm 50...

any suggestion?? >< Thx

helo to all the sifus,i have a question in my mind,can the satria neo oxygen sensor used in saga blm???coz currently i am using the wai xxxx 421 extractor for my car,until recently i wanna try satria neo 421 extractor on my car coz the 2 Y joint is equal height,unlike the1 i using now from wai xxxx is 1 up 1 down,so i tot it will be more balance???so i tot of putting the o2 sensor at the end of the 2 joint but found out dat it was too short,and i tink dat putting the o2 sensor at btm will have more accurate reading of a/f instead of putting on top isnt it??

so my question is can the satria neo o2 sensor used on saga blm coz its longer???and o2 sensor at the btm of the "2" joint will not have the idling not stable problem rite??and last one,isit worth it for me to replace the extractor???coz satria neo extractor is longer??thx a million.....
