yup..TA22 old and full of rust..

While that may be true in many cases, there are reputable shops (not tuners) who do quality replications of tuned extractors ie. Mugen, Spoon, TRD, etc .... what consumers have to know is how to differentiate it and know that what they are buying is not a replica of their stock extractor.

For those Honda or Toyota, that might actually be a good thing.

but as for Proton, or Perodua... there's almost no real tuner item to replicate

Question:
i)What are the benefits of a "swirling" type bullet
ii) Why are there "longer" and "shorter" swirling bullet?

Currently I already have a MUGEN Twin Loop exhaust (and mine is not VTEC engine) on my 1.3L with stock piping and stock center box.I find the twin loop did improve my low-end torque until 4000RPM but after that, the engine struggles to meet the 6000RPM. Sometimes it will be stuck at 5500RPM for a long time.

So the exhaust "specialist" suggested I get the "swirling" bullet compared to normal "RM 90" bullets, apart from enlargeing the pipe.

how much power do u to get from a bullet? be it rm 90 or rm 200?

any forummers care to share their experience on installing bullet?

swirling bullet is purely gimmick. the best way is not having bullet at all. or at least get a bullet with the smoothest inlet.

I would like to stress over and over again. Bullet does not add power. Show me a dyno chart to prove that bullet adds horsepower or torque.

That is what I wanna hear, the truth is out there and now the truth speaks for itself. Thanks SoulFly.
Okay, that really clears the air of my doubts cause the exhaust shop man (a 40-ish year old man) keeps promoting about this "swirling" bullet.

I keep on searching in Google for "swirling bullet" and only found 1 which basically praises the product itself. Damn.

So from your answers, I should either:

i) Get a straight flow bullet (and I think thats the cheapest)
ii) Straight Flow mid box, but fear it will be noisy. A little noisier is acceptable, but excessive noise enough to drown my ICE is not acceptable.

and enlarge my exhaust piping to around 1.8".

OK, now where can I find this (or equalvalent)





I have a feeling this stock standard bullet is really "empty" (no fibre) at all.

a midbox would be a better noise supressor than a normal bullet. I personally use a straight flow midbox which is modified into a rear muffler. i have another bullet in the center of the exhaust piping

my car exhaust setup is:

[extractor][2.5" piping][bullet with 2.5" inlet][2.5" piping][midbox straight flow 2.6" inlet][2.5" piping][4" exhaust tip]

... and it's not noisy. i pass every JPJ roadblock so far.

as long as the bullet/midbox have good quality fiber inside... noise reduction should be good

wanna ask, for a Nissan Langley sedan with engine E15T 1.5 turbo, which setup is better? 4-2-1 or 4-1?or it doesnt matter, just according to my driving style?



i just got the car from my uncle, and im completely clueless about turbos and nissans

how could you choose between 4-2-1 or 4-1 while you have turbo?

seriously, have you checked the engine bay itself? and imgine how would you want to fit that 4-2-1 or 4-1 headers later?

hehe, thats y i told u i had no idea about turbos and nissan cars

i just received the car, and due to the time constraints of my studies, assignments etc, (right now oso doing unfinished assignments) i was unable to completely "study" the car yet.so im just guessing it based on my dad's Saga LMST

edit: i just saw the sub-title "for normally-aspirated car" guess my question is not valid eh..

urm.. not really not valid. Its just not quite reasonable.

For turbocharged cars, there is a turbine that being stuck there at the exhaust manifold. The turbo runs by the gases that coming out from the engine. Basically, the setup is like this:

[4]-[turbo]-[1]

hehe..thanks farique for the info

E15T eh?? tat's 1 rare engine...

join www.retronissans.com

we are a bunch of nissan drivers.. some have E15T in their sunny's engine bay..

has anyone hear about the Cyclone2 selling in Eneos? Is it useful?

Sorry, do not discuss anything about gimmick products in here ok. Strictly 'real man' intake/exhaust modification discussion.

how bout the twin entry turbos? i think it's 4-2-turbo-1..like the one used in the 3sgte twin entry system also like 6-2-turbo-1 also got..eg..t88 turbos..correct me if i am wrong..thanx

Precisely what i've always emphasized.. even if it does make a difference.. it's very-very minimal almost to the point where it's unnoticeable..

What are the modifications that I need to put in my LMST 1.3 in order to bring down the noisy sound from the current stock exhaust system or maybe to a silent mode if possible? At the same time, I need to maintain:

1. current FC
2. pick up power
3. maybe some performance boost

thanks
