Muffler

[Johnar713]

Mga pre,

What will happen kung tatangaling ko ang primary muffler ng OTO ko? yung secondary muffler is a free flow type.

What will be the effect?

Need your ideas and oppinion.

Thanks a lot.

Pros: Better exhaust breathing of your engine resulting in better performance.

Cons: Sobra naman ang ingay nito.

Better option may be to increase the diameter of your pipes or headers. ;)

Primary?! Secondary?! :confused:

Primary mo yatang tinatawag is "axle-back" then yung Secondary is "mid-pipe" [?]

Straight-through axle-back would be TOO loud. Bili ka na lang ng cat-back exhaust (with high-flow cat) or wala namang regulation sa cat converter sa pinas, wag mo na lang lagyan [?]

effect? prolonged use will leave you with hearing problems. :D

better simply replace the primary muffler (resonator) with a freeflow resonator... Nodalos typically call them powerflow. Get a "medium" to "large" size resonator to help minimize the irritating drone of your exhaust.

magakano b ung resonator? at ano mas ok na resontaor kasi sobrang ingay ng muffler ko lalo na ung long travel nagasaswa ako sa tunog.
help me naman tnx...

Well, I recently just had a custom freeflow resonator done because my car had 2.25inch pipings. I had it made at FREMUFF in San Juan and costed me P1500. But the resonator's piping is a single piece instead of the typical welded on to the resonator's body so its more resistant to the bending forces that cracked my older resonator from Nodalo's.

Comparing the sound with my old and the current resonator, my car is quieter now.

I remember Nodalos resonator typically costs around P800 to P1200 depending on size.

BTW, CPM Muffler House also has a good selection of mufflers & resonators.

BTW2, FREMUFF San Juan typically tends to overcharge a bit so be prepared to haggle for the price.

Salamat ng marami sa advice nyo...... baka nga palitan ko na lang ng free flow resonator. Salamat po ulit.

resonator is iba sa baffler right ?? is the resonator the stuff filling inside the muffler ?? curious lang ako , heard of it but never really paid atention ano ang resonator . tnx .

resonator is basically a straight flow construction with fiberglass filling the insides. BTW, this is not the muffler.

resonator: para medyo hindi maingay ang tunog ng auto mo.

somewhat a silencer ng konti.....

so to say.

[mojako]

will changing the stock resonator to a free flowing resonator improve power? May freemuff freeflow muffler ba na hindi maingay?

[Karding]

resonator is part of some muffler, as far as I know, and it's the baffled type (OEM).

SILENCER is another part to quite your muffler.
Apex'i Silencer



Straight-thru Design:

"Straight through design" mufflers are the most common import mufflers today. straight thru muffler are "glass-pack" (a fiberglass sheet wrapped around perforated tubing).
This will cause a relatively low suppression life. Carbon will attach to the only exposed side of the fiberglass mat and create a sound reflective surface instead of a sound absorbing surface. Also, most of them do not use any stainless steel wool to protect the fiberglass from burning off, which makes the exhaust louder. These types of muffler will result in a short muffler life.

Baffled/Chambered Type (Most OEM)

Most of the OEM muffler and Aftermarket mufflers for normally aspirated vehicles (non-turbo) use baffle type systems. This construction uses baffle plates to bounce the exhaust noise around inside the muffler to suppress the sound. This is a very effective way of suppressing the sound but at a high engine speed, the baffle plates becomes restrictor. The restrictor will cause high exhaust pressure and it will be difficult to gain peak power. Also, some of the baffle plates are not very resilent so it can start to rattle and produce an unpleasant exhaust sound.

Inner Silencer Type (i.e. some Apex'i muffler)

Some aftermarket mufflers today have insufficient sound suppression so they include an inner silencer. Most of these silencer have inside diameter of 35mm ~ 45mm (1.6 ~ 1.75in). This becomes a restrictor and it can cause a 5 ~ 7% power loss. Almost same as stock! It really defeats the purpose of installing a performance exhaust system. Also by having the additional silencer will increase the cost of the system. This is the reason why we do not offer these type of mufflers.

Now, look at GReddy exhaust, a very nice piece similar to Prodrive design.


I hope this enlighten some of you...

eto sample ng Prodrive Axle-back ko. First ignition start is the OEM then almost halfway ng clip naman yung sample ng Prodrive.
Boxer engine throaty sound when WOT but real quite on idle.

some say it sounds like a 3cyl motorcycle :bwahaha: and most people say it sound scary when WOT, the rumbling sound....

dude ung mga nabibili ba na muffler na di well know muffler and headers shop e nakakabawas b ng power or horsepower?
magkano b aabutin pagnapkabit ako ng full exhaust system sa fremuff?
hope you will help me with this problem.
tnx...



















peace!!!!!!!!!!!!!!!

jevy0712, depende sa construction and material used. At the end of the day, it all comes down to how much you're willing to spend to get a quality one.
