Quietest possible muffler for our cefiro

[ceffy32]

Hi guys,

I have a A33 VQ20DE. Changed my Y-pipe and put a bullet to replace the center box. I noticed the surface of muffler is rusted and there might be a hole soon as it's getting much louder since the day i fixed the y-pipe.

Wondering anybody here put a sport muffler on their cefiro? Currently im eyeing on Tanabe Hyper Medallion and Fujitsubo Legalis R. Uhm, mind me asking, are they straight flow or S-flow? I searched through the marketplace and noticed some Legalis R have their outlet near the arc of the oval, which stated as s-flow and some at the center of the oval. I assume that s-flow is more suitable for our cefiro, correct if i'm wrong.

Anymore recommended muffler in your mind for our cefiro? As quiet as possible, really hope to remain the 'silence' of our car..

Thanks a lot guys. :respect:

Add: I'm on 2" piping.

d hyper is straight flow & thats wat im using now..consider loud oso
don know if they oso produce s-flow for hyper
for more quiet recommend 2 install a silencer(pre-muffler which usually in d middle)..u sure smile on ur face with s-flow

you replace the Cat, that why it get louder, the cat is also use to damper the sound. the bullet is a straight flow, it sure loud. Change to a good center box that will reduce the exhaust noise.

I guess there's different type of flow for hyper medallion, but not sure if there's s-flow. I was offered by JFA with their s-flow, which one is better actually, sport muffler or aftermarket muffler?

i removed the center box because it had faulty, FC drop to 350km/tank and the exhaust sounded too rough and loud. hopefully a good muffler will make the sound tolerable, or adding one more bullet perhaps.

Yes, it's stock muffler. not lubang maybe, just the surface is peeling off. any area around selangor has a lot of chop shops?

thanks for those replies guys...

Thanks for enlighten.

there is a bunch tht will help

tanabe gmedilion
hks silent power
rsr invidia
hks super dragger is bassy

 

[ceffy32]

was looking for HKS silent hi power as well, but since our cefiro's muffler is visible even from far, putting a circular shape muffler would not be that nice in my opinion. and therefore i go for oval shape muffler. Thanks for recommending though...

did mine at JFA with 2 flex pipe and 2 inch piping, cost me 480, which is a little expensive i felt.

Simple get a stock muffler , whether chop shop or brand new , end of the story. Quietest of the lot. Any sport/performance muffler will produce some sort of sound . Believe me, I have been toying around with exhaust systems since my 1st car (Mazda RX-2), hehehe..
Btw, quietness of our cars makes them sounds expensive..(especially inside the cabin)

Just my 2 cents.

my one no more cat when i bought it, may be pre owner took out..

Aiya , no need catlah , no mouse around wat, hahahaha , just joking. OLd cats r very restrictive to the flow of the exhaust especially during high rev . There are no regulation here in MY to install or compulsory for a car to have one unless you are living in USA. So wtf, just DE-CAT the cat and feel the power difference!

Cheers!

Thought of De-CATing the exhaust too, but worried on the effects that might have on ECU/etc... is it just take out and drive thingy? no need extra tuning whatsoever?

Anyway, after removing the CAT, what do u guys replace the section with? Just a connecting pipe of similar diameter will do??

Yea, de-cat and drive. But i think it's best to reset or ECU, letting it to retake all the readings.

I doubt if u can just reconnect a similar diameter pipe. Most of us will remove the stock Y-pipe, and redo a new y-pipe. Exhaust shop will know what to do. After removing the cat, if u still want the silence, replace it with a bullet or high-flow cat.

reset ECU means take off the battery + and - terminals right?
