thom_chai, for ur 1.3 wira, there's only one sensor which is before the cat, so i dont think it'll screw up the sensor.egiewan's driving a civic meh,different from our proton. but u must know that removing the cat will increase the noise a bit..im still modifying my setup to reduce the noise

I would say.... adding more than one bullet is idiotic. 3 bullet is....

Better spend on good muffler instead of adding too many bullets. Bullet restricts exhaust gas flow and installing too much of it is just a waste.

You get better performance/noise ratio with good muffler plus 1 bullet, compare to crappy imitation muffler with 3 bullet.

Loud exhaust (esp those N1 type like APEXi or 5Zigen) are originally meant for track usage, not road... that's why noise is not a concern.

For good workmanship... go to William Exhaust @ Kg.Wireless.

As for exhaust tuning (exhaust diameter, header type, mufflers etc.) you might wanna ask the experts.

Anyway.... you mentioned that you're driving a Wira 1.3 w/ mmc system... right?

You can remove the cat... no problem.

my car(4g93p powered) is currently running on a 2" piping(original route from engine, no bullet) with a hks drager lookalike muffler. Not that I have any problems with it(except being loud), is it a recommended setup?

My system is pretty much stock. I removed the CAT only. From my ears...it sounds pretty much like stock but when I rev abit high...the sound is more garang

Haha the sound of vtec and also help destroy the environment.

thx for ur insight.anyway,i managed to find a halfcut muffler from a mirage (IIRC got jasma tag ).izzit advisable to install it?can i expect noise reduction compared to my stock satria muffler?

JASMA certified muffler are street legal in Japan and the noise is usually quite low.... unless the fiber inside already finish.

Who cares about the enviroment...this is not Europe Better ask those JPJ to tahan those damn lorries and buses with thick smoke than my car

-By removing the center bullet n using direct pipe setup:
1) Is it will effect the fuel consumption?
2) Performance wise?
-Recommend me exhaust house in serdang, anybody?
-Thanks

Any recommendations for a wira 1.5 auto?
My mech told me not to do anything to the exhaust system as its quite sufficient already. He advised, If i really want to upgrade.. Get a bigger bullet. Leave everything stock .
Cause if you mod the wrong thing, your fuel cud go up and loss in power.

I feel the Engine is a bit sluggish to rev. Tought maybe By changing an extractor or sumthing will improve it. Especially between the range of 1.5k -> 2.5k. Above that its quite ok.

Changing extractor definately helps, it frees the engine up and gives better torque at low revs for a 4-2-1 config, just don't oversize the rest of the piping.

guys, what do you think of this setup for my 1.0 A Kelisa.
-3-2-1 exhaust manifold
-1.8" piping from exhaust manifold through 1 centre bullet until the muffler
-using original piping route

what do you guys think? shall I decrease the size of the piping? what a good decent muffler brand that really recude the noise?

Thanks.
