just wanna know whether your car is auto or manual....
hhhmmm.... i think running a 2.0" piping on a 1.5litre enginer should be
too big liao... try use around 1.6" or around 1.8" piping
or another alternative is combine 1.6" and 2.0" piping... some exhaust
guys should have tried this setup...
try not to use any bullet, although it will be louder, but find a muffler
that is not that loud...
ok, after you change the filter and exhaust, did you send your car for
tuning? ignition timing ? air and fuel mixture?
how old is your wira? send to your mechanic to tighten your tappet..
hhmm.. try and see... should done some tuning to your engine to get a
better performance...

i used a muffler and at the center of the piping, there were another
muffler(dono what they call it).
after the change, i never send it for tune up. the car using a
carburetor, so, i'am not sure is there need for the mixture adjustment.
normally i send the car to proton services center when it reach 5000Km.
i don't have any idea, where to start. what should be modify first and
what the effect.

since your car is carburetor, then you better stick to your original air
filter. even if you modify the air filter, it will suck in hot air which
will result in a major loss in power, somemore fuel comsumption goes
higher.
but i still think that 2" piping is too big lar..
nevermind lar... u can have a try with it first...
send your car to a mechanic and ask them to tune the engine lar...
normally, they will tune the CO level(which can consider the mixture of
air anf fuel), and they will adjust the ignition timing and also the
idling speed for you..
i think any mechanic should be able to do it for it...
the cost for tuning should not be more than RM30

4x2x1 exctractor...
the mixture also had been retuned...
so now my top could touch around 180Km/h, but the acceleration still
hampeh la. take about 2 minutes (i guess) to touch the top speed. So, im
considering to improve the acceleration la. Changing the engine is one
solution, but cost me to much, for i'am still a student. so I thingking
to using the force induction, but would never consider a turbo for i
don't like the wasgate sound and the lag... I am thingking about
supercharger, maybe a low compresion one la, (less than 2bar(max))...
can my standart 4G15 wira 1.5 (manual) be fitted with those supercharger?
is there any modification to the cylunder need to be make? or the
standart piston need to be change to high pressure piston (including the
piston ring and head gasket)...?
if yes, do anybody know any garage in Shah Alam area can installed those
thing, and how much it will cost la?

force induction = turbo !! hehehe....
2bar boost is a LOT!!! hehehe...
your car can fit lar.. but you have to change a lot of things
so, it's not worth it.. transplant one engine more worth it..
