What extractor u using? Your twin loop muffler is how much inlet? 2.3" piping should be good enough. I'm concerning more on your muffler and extractor piping size.

i'm using original dc2 muffler. b18c gsr.
n btw,if i want to put back the bullet,where should i put it?at d front or the back?if want high end power.

It should be the same but my own opinion will be fitting it in the middle.

CAI -> stock filter -> -> 4-2-1 powerzone -> nenas -> str8 flow bullet -> stock centre pipe -> Wira-SE standard str8 flow muffler.

Exhaust setting okay already. Maybe not a good idea to WISE stock muffler since it will soon produce funny metal sound.

Hey bro, the setting okay. But as for Campro engine, best if you use straight flow muffler at the back with silencer on or you can try using a swirling bullet right after the flexipipe before the piping leads to a straight flow bullet. That's best if you use 1.8" piping, 2" will reduce you pick up(worse coz' campro engine pick up is slugging). My 2 Cents. U can call me if u need more of the references.

ya! manual~ d setting ok?

Since WISE muffler is straight flow, change if you mind the sound(after 4k, some hollow metal-knocking sound) and of coz' if you wanna feel a little better throttling response, don't hesitate to change your stock midbox with a bullet.

thanks kweng84..

No problem :D

1 question, what's the difference between those straight flow n1 style mufflers compared to straight flow mufflers with tabung other than the sound?

Performance wise, there is slightly different depending on the "tabung" size. N1 style muffler usually has better response compare to the muffler box type. My 2 cents.

Bro, what rear muffler r u using? Piping size i suggest is 1.7" and if you have Stage 1 mods, go for 1.8". If you want it quieter, go for long midbox(flat type) and if you want better response in pickup, go for straight flow bullet. My 2 cents.

Erm, just to confirm, is this L2 ENGINE or it is just a BOT with L2 TURBO? If L2 engine + manual tranny, you can go for 1.8" piping(a little bigger size for the downpipe) with one straight bullet and one N1 style muffler at the back. If auto, u can have 1.6"-1.7" piping with swirling bullet and straight flow muffler or u can have sflow muffler with a straight flow bullet. My 2 cents.

my frens car is a cefiro auto 3000cc engine. going to mod his exhaust setup to something like this
engine(modified air intake with CAI)--extractor(stock)----small swirling bullet---swirling bullet---straight flow muffler...piping all remain same
is this a good setup?

Hi Bro, thanks for your advice.
Well I think I might need to change my muffler,
because it is freaking loud at the moment,
and I can feel the shaking under my seat when I rev high..

I will come and pay u a visit by next month to tune up my exhaust system..

 

[kezman]

kweng, my muffler is kinda loose. whenever i go over humps & bumps the muffler will hit the rear bumper. is there any way to minimize the movement? can i weld the muffler (now i'm using those rubber connectors) to secure the muffler.
