4-2-1... that not stock liao... hehehe...

shall be quiet now :-)
eh not necessarily leh. The stock Wira SE 1st batch (when they still had the exhaust mods) was stock 4-2-1 and the resonator plus muffler were special.

Eh?Ye ke?
I tot 421 is stock one,oh my bad
The mid pipe had one bullet only then straight to the rear muffler
So you're using 4-2-1 header, a bullet and a stock muffler? I assume it's S-flow? Why did you opt for S-flow?

stock is S-flow. No wonder macam constipated la. But now it's quiet so live with it lor.

okay....Because my myvi 1.5 is 4-1 stainless steel one.Pick up quite nice lahh
There's a lot of debate about this but what I know is 4-2-1 on a Myvi is physically impossible to get a proper length header done. The car is too short to do a proper length 4-2-1 and therefore those that claim to be 4-2-1 might be problematic in terms of exhaust flow? I dunno.

I've been using this gauge for like 4 to 5 months now and I always wonder is my reading of the vacuum gauge healthy? When the car is cold let say in the morning the reading is around -0.46 bar. (note my reading is in bar not cmHg or inch/Hg) but when driving for a long time or let say the engine has reach its optimal temperature, the reading is around -0.24 or -0.22 bar which is close to 0 bar! I'm using a Toyota Vios 07 onwards model. I tap the vacuum line at the intake manifold vacuum hose...
