Btw, can anyone tell me where i can order open pod's piping for satria neo campro? If you remember my previous post, i want to do something like in the 2nd pic

Also, who can i find to make a heatshield ah?

Thanks a million guys

Guys,
If i remove my mid bullet,no top speed?

my daily ride is a waja 4g18, i changed the exhaust to wegow 4-2-1, wegow 2" piping with 2 bullet(similar or same as r3 piping) and top cat sflow muffler. the idle sound is bassy and not loud. is there any way I could reduce the bassy sound and make the muffler sound loud only when accelerate? just like those FGK muffler that is very silent when idle and loud when you accelerate hard?

also, i'm on auto transmission and seems my low end suffer abit, do you think it'll be good to change one of my bullet to a midbox to have more backpressure and at the same time reduce the exhaust note when idle?

please help.

I'm driving a Gen 2 1.6 Campro IAFM engine. All stock parts but planning to start changing the exhaust system.

I need advice on what to change / buy.

and if possible recommend some shops for me to change it as I live in K.L area.

Thank you.

oh, okay. thank you.

but apart from him, is there anyone else?

any other reccomendations?

Can also look for the pressure activate valve muffler like the one in the FD2R. Low end works as normal muffler, and when pressure is high it opens and works like straight through muffler.....

That one is a silencer, he's referring to something like mugen twin loop(original).

so in other words mfa quality is better compared to kweng?

Good sh*tty?

omg. means i must choose between good workmanship and good quality?

guys, need professional opinion here..
my current exhaust setup is:
4-2-1 (wegow)
twist bullet right after the pipe joint (after flexipipe) =2.0" inlet/outlet
oval midbox after bullet =2.0" inlet/outlet
everco s-flow muffler = 2.0" inlet
1.6" piping

may i know what effect should i expect if i change to straight flow muffler?
or a long 4-1?
btw, car is 1.6l campro auto
current setup got nice pickup but top slightly suffers (quite heavy near 170kph onwards)
please advise, thanks

bro eventhough you limit your car at 190kmh, i'm sure that you can outrun cars anytime you want to.. because of your 'siput sedut' there
as for my NA car, AT some more, i need slightly higher top end to do so, i suppose..
various shops, and no its not secret recipe from any tuner or whatsoever, just a mix of some recommendations with own experience of trying few type of extractors with few configs of midsections..
but i havent try straight flows yet (kinda noise/beng factor).. thats why im asking here first

btw, the 1.6" piping size is derived from r3 piping setup..

i already got good pick up (satisfy me enough for an AT NA), just need top end a little bit more that might be useful in the highways.
I think so too, but still i need to consider first whether to change back to 1.7" (stock size) or 1.8" (with relocate bullets & midbox further back a bit hoping to gain back pickup loss due to bigger piping).. I'm in dilemma now
Please advice.

btw, i seldomly drive over 5k rpm (mostly till 4.5k rpm like that only) unless when i wanna get top speed.. will a straight flow muffler gives me advantage in this 4.5k rpm region? btw, campro redline is 6.5k rpm iinm, gotta check back..

Extractors power:-

3k rpm below : good 4-2-1 > standard > good 4-1

3k rpm above : good 4-1 > good 4-2-1 > standard

Highest rpm (normally above 6.5k) : all the same

Need at least 1.5k idling and the engine is totally different oso~

Hmm... Can 4g15 SOHC change to DOHC without changing the carb into fuel injection?

I think quite accurate as my 2.0 turbo only using 2.5"

I think bro. low yat 82 can advise you better on this, but basically older days we call them 1/4, 1/2, 3/4 and full cams.
The higher the cam the rougher the idling but power gain is much better in the high end but poor in the lower end.
Lower cam have better idling and good lower end but high end gain is less, so you have to choose properly.

For mushroom type or open pod, best is couple with Cold Air Intake (CAI)

i disagree with it...piping size doesnt always relate to CC...its more on the amount of power u have and where in the rev ranger is that power at.

take for example 1.6...campros and CPS goes up to 2.0 and the gain is pretty decent... even CPS stock piping size is 2.0....go bigger and kaput...

but when it comes to the 1.6 MIVECs and VTECs...although the 2" pipes is pretty decent for those engines but they benefit more with 2.3" especially since most of the peak power is at the higher end of the rev range and the bigger pipe size really benefits the higher rev range.

my 2.0 VTEC is running 2.5" pipes.. and its good...so good.. 4-1, 2.5" pipe, 1 midbox, no muffler.

i also have an exhaust cut out valve.. so when the valve closed the exhaust is forced from a 2.5" pipe into a 2.3" pipe and s-flow muffler.....i lose 15hp about 1.2kg torque. tested this on the dyno just yesterday

so max n/a is 2.0"??? big big no.

In this case, how do I improve back my low end? add mid box?

current set-up, 4-2-1 , 2 small bullet + s flow muffler. running on 2.0" piping.

owner claimed with 2 mid box top speed 245km/h, with 3 mid box up to 265km/h 

larger pipe will be straight flow, this mid box is 2 way system..not sure how 2 way system mid box works though..

u can drop by at Exss Work workshop in Setapak for further info..

hmmm...
put 8 how? haha trololol
ok la so put 2 top speed nice?
sound also quite a bit right?

dei..i'm not that gila mau 265..i mau 200 enough..190 pernah dapat..

Our DYMM King Amir's of course takda feeling.... He berani gila babeng and his car is 1.3 but his 1.3 modded one  ...

Even my Neo 1.6 has tough time chasing him.....

huge difference ah between normal muffler and blocked muffler?

Those mid box with raised holes have to be fitted the correct way, but what is blocked muffler?
