Cap ayam wegow

RM150 .............. angpao money pls cover it lol

icic... now i got it already. in term of the performance, decat and change the whole extractor, which 1 better?

the best way is to feel it yourself...

aiyo... share a bit mah...

Put it this way lo... Extractor big mod, decat small mod.

Cost also big different, Improvement differences i dont know...

Got ask all also same manufacturing period?

I very innocent leh. Where got cheong and fnf. fnf hammie lo

Time to find new sos

Decat = 4-1 why? because 4-1 extractor if buy long ones also no matter what have to remove catcon also unless u plan to put at middle of the car la. so decat + stock= 4-1 system with super budget style.
Difference? air flow. There are reason why those branded extractor keep saying their internal pipe is smooth, using mandrel bent, just to make sure inside pipe is smooth and consistent internal diameter from engine block to your exhaust muffler to avoid turbulence. so if your system got a lot of cut here and there then screw here and there, it will affect since not smooth and consistent but difference very little in our car la. like few percent only. if changing whole system to jba that uses laser welding to avoid those unconsistency also gain like less than 10hp? then few percent of 10hp is like so little...... unless your car is supercar which affects a lot

tmr kl apahal a???

btw today i saw a 5zigen midbox in the middle of the flow there got bump up, what's the effect arr? it's like this (> <)

Got demo la..

Let's say u turn the water tap on. Water will be flowing out of the hose at a constant rate. If u squeeze somewhere in the middle of the hose, what do u think will happen to the water flow?

Brooooom!

Only sound diff or power diff?

why don you try both car with decat and change whole exhaust?

Sound not much difference lah.. Power difference also very minimal... Improves a bit, but at most around 0.2-0.5 hp..

Oic.. After put in 5zigen my car from tiger become cat already.. Vy quiet..

U took the silencer bullet?

I think so... The inner part is straight flow, no swirling... Now smoother and less rough, reset ecu as well just now.
Hopefully can rest my case this time.. Coz 5zigen s flow freakin expensive >400 per piece
