.: Exhaust Modification Corner :.

The exhaust is trapped and released slowly that is why high end suffers, but you should get better mileage....
This is similar to Saga LMST noisy exhaust - better performance, my lady friend exchange to the Saga quiet exhaust - better mileage.....loss performance but being a lady she prefer quiet....

most probably going to change it again, damn waste of money.hopefully i can trade in the stock exhaust for some buck and reduce d cost since it been used for few day only

Different exhaust guy gave different opinion on my intention to decat...

This guy recommended a flat muffler instead of the round muffler....@ RM160 stainless steel muffler

He says flat one is more silent and better power...

Any professional or views from anyone?

Is it a flat box, but the pipe inside is still round?

Things that affect the sound in a muffler is the sound absorbing material used inside, length of the box and the tubing layout inside the muffler box. The box pattern is just a design.

LA, that guy that showed you the muffler is a straight flow or S-Flow type? The main 2 types which are very common is the oval type box or the round type box. Regardless of flow pattern, oval shape box packs more wool to reduce the noise compare to a round type.

Just my 2 cent

Yup, the tubing holes design also. Straight line, swirling design, and so on...

Hi ...

Newbie here. I am driving a Toyota Corolla SEG1.6 (1996 model) here. I am thinking to modify my car now. Looking for some mods that can improve acceleration.

I am looking for Custom Banana Manifold for 4A-FE engine. Is there any custom made available out there in the market? i plan to use 4-2-1 extractor on my car and straight flow muffler also ....

Will the Modification Above improve car acceleration and pickup or not? Is there any side effect on the car and will the JPJ kacau my car o not if mod it this way? The car is for Town use and sometimes outstation use too.

Thanks

TR,
I am not sure of its flow, I think its an empty, straight flow ovally square shaped type...

Got to check further with him...

 

[TitanRev]

LA, I think the one he showed you should be those straight flow type oval shape box. I have seen some on cars before. I think s-flow will suit you more if your car is AT. Plus straight flow in long distance drive can sometimes be annoying in the cabin due to the resonance from the exhaust...the bassy hum....

OK TR,

I will ask for the S-flow, but do you think it will be suitable for my manual transmission car?

 

[vr2turbo]

Is the S flow one something like this....

Buang the swirl bullet. It doesn't do anything but ruin the flow of the exhaust, just replace it with a long straight through bullet...

Changed my exhaust system yesterday on my manual 850cc Viva

3-1 extractor
decat
1.6" piping
bullet
straight flow muffler.

Did it from kweng. Satisfied with this setup, pretty good top end acceleration, but minor decrease in low end acceleration. Just sharing :)
