questions about exhaust system

[rollakid]

slower.. took me more time to go from A to B because you know kuching's road all potholes, now i have to slow down for each and everyone of them instead of ram through it like last time.

or else my bone is going to shatter.

Let me check further ok... not saying who is right or wrong here.

I believe 4-2-1 is for top end whereas 4-1 is for better accerelation? Not the other way round !!

Tri-Y vs. Shortie vs. 4 into 1- The Tri-Y design is for building maximum horsepower and torque in the idle to 4500-RPM range. They work well in motor homes and pickup trucks that need more pulling and passing power as well as street vehicles with stock to mildly modified engines.
The 4 into 1 or long tube style header are built to maximize the engine output in the mid to high RPM. This header will have larger individual primary tubes flowing into a single collector. You will find this header on high performance streetcars or at the drag strip.

Our Headers are offered with either 4 into 1 Merge collectors, for maximum power potential throughout the full RPM range, or 4-2-1 Tri Y collectors, for maximum low to midrange torque.

Am new to car modding even though I have my Kancil for nearly 6 years. After a full sound system installation, now I'm venturing into some modding, exhaust, engine etc.

I was just wondering about the exhaust recycling mechanism for my 850 auto Kancil with a carb. There's this output from the extractor which goes into a piping and then goes into a small device beside the engine which then outputs the air back into the air filter box.

One thing, if I change my extractor, the new extractor won't have this output and this 'exhaust recycling' device won't have any use anymore.

So, if I remove that device, what difference would it make?

4 - 1 is for track car wan... so basically sflow is not as noisy as straight flow wan rite? but coz i see some sflow they oso dam loud and noisy -.-"

 

[weikhee86]

erm, s flow is not that noisy. its very quiet esp during idling. even better than stock's sound. only during gear changes and when u rev it then u wud hear a little rough sound. other than that its very quiet. i've been using hotbits s flow muffler and its very quiet..even better than stock and my fuel economy has been improved. one question, is it necessary to fix bullet? what difference would it make?

 

[kelv!n]

yea.. can anyone tell me whether is it necessary to fix a performance bullet since our car will ady have a bullet ady wan... so i was juz tot changing to a longer piping, remove the CAT and put in a kakimotor sflow muffler... can anyone give some opinion on it?

A bullet is to reduce noise.

Those grooved innerwalls gives some back pressure to help N/A engine for pick up.

Go for mendrel-bent pipes, they do wonders..... :)
