Exhaust Silencer

PART 3 - COMPARISON


BIG HOLES VS SMALL HOLES with almost same hole area

1) noise suppression
SMALL WINS

2) back pressure
SMALL HIGH BACK PRESSURE

3) power
BIG WINS

so, the conclusion is
POWER = LOUD = HIGH CONSUMPTION = MINIMAL BACK PRESSURE


small holes are like a crowded stadium with small small doors for audiences to escape

big holes are like a crowded stadium with a large door for audiences to escape

although all small doors' size all together = 1 big door's size

the big door would clear the audiences faster

THE END

No bro, mug sifuu~
Want join the mug's world?

New technique.

Drill sufficient holes to suite your taste.

The process will be DRILL --> TEST --> DRILL --> TEST until you are satisfied.

After all those test and drills, i end up like this.

I am satisfied with this setup. The LMST big exhaust is louder than mine.

Power wise, dropped dramatically. Use until bo syiok only take out. :slug:

 

[Northiswara]

ur this setup blocks a lot of the muffler tip mouth. i think ur previous setup with 2 big hole looks better than this setup. this setup sure give u a lot back pressure. FC wise got improve??

Ya bro, high back pressure. I am not sure about the FC but car moves like turtle. I am testing it right now.

 

[Northiswara]

move like turtle? for sure one larr. if u got vtec engine die lor............ vtec canot open. haha.............

hahaha... no need silencer lah... u power freak dun induce so much backpressure... ur turbo need to push out air as fast as possible so can boost properly.... kekekeke...

 

[ken12292703]

This is just a temporary relief for my ears.

The sound is killing sometimes when we are not in the mood. :sleep:

 

[Northiswara]

so how is the FC?

 

[ken12292703]

so how is the FC?

Hi bro, a couple of days the results will be out.

Still monitoring.

 

[Northiswara]

okok.............
can u get used to this exhaust setup? i mean less power.

 

[ken12292703]

How about you?

I don't mind if FC improves. A quieter exhaust also can save us lots of $$$

So far still okay, don't have the ummpphh like last time but still acceptable.

You want try bro?

 

[Northiswara]

i feel like to try but after i drive waja, sentra, vios with stock mufler i feel that stock mufler sucks cozs the power not so smooth coming out. haha....
still i like my S flow. my s flow not so noisy larr. but my power from 1,000-2000rpm is kinda slow. if use stock mufler sure my 1,000-2000rpm will be more powerful but after 3000rpm it will sucks.

i think it lookd kina weired lah with those lubangs..... why dont spray them matt black to make it looks like a hole it self...
