without muffler the sound sure dam shiok and the top end would be more powerful as well
however you would lose quite some torque from the reduced backpressure
which means u will have to downshift more often in daily driving situations coz u will be lacking torque down low
so the choice is urs
but basically for daily driving try to use a muffler for better torque
but if its a all out drag car just dont bother
instead u can try to make a side exit exhaust so exhaust gases can escape even faster :top:

u can go without muffler, but it would be damn loud, sure will kena tahan by JPJ or polis traffic.
most of them are using muffler, but its placed in the middle. if u bend down u could see it.

Turbo cars aren't that loud with open down-pipe if you compare them with N/A engines. Sound is reduced because turbo takes most of the exhaust. Don't know weather JPJ or Polis will have issues or not as I am not Malaysian. :) But you will love the top-end and you will be in love with the sound when turbo kicks.

i prefer the torque to be on tap, so i opted sflow muffler design for ALL of my rides, be it na or charged

Indeed for low-end you need torque but for high-end you need more HP rather then torque and with short open down-pipe to push the vehicle more fast. As exhaust departs quickly turbo spools more efficiently. But in the end with open down-pipe you'll be missing your BOV whistle :D. As the engine sound kills BOV whistle :P

oh yeah i know this sound
and i think xtremeleo also knows this sound pretty well

hehehe, and even dat gonna be quiten down soon bro, hehe

hehehe, and even dat gonna be quiten down soon bro, hehe

heheh sadly yes
but let me test first with the sound on full boost
kasi steam sikit
then we go s flow for added torque :top:

Why don't you guys do a DIY. Make a electronic throttle at exhaust pipe. When ever you want you just press the button throttle will open and exhaust will pass quickly and when ever you want to close its on your wish.

 

[xtremeleo]

okie dokie bro :)

i think Police/JPJ more attracted with big size mufflers compare to straight...

 

[peterj]

1 problem using diy electronic exhause valve is(diy using power window motor and switch), the jamming problem....if the thing jam, need to do some wrok again ...... since we know the exhaust really hot

 

[boi]

why not use manual one using bicycle gear cable + throttle body...

not really
it doesnt matter how big ur muffler is coz JPJ call u for inspection based on the size of ur muffler there is no law against the size of the muffler
however the sound the muffler produces is a whole other thing
they will rev ur car too test the sound ur exhaust system produces then if too loud ur in trouble

i mean not after u have been hold by them...i mean for physically watch during we approach any roadblock thats mean normally when we approach any roadblock of course the traffic will be slow and normally we will running in idle rev so the sound not loud yet...thats why when they saw your muffler small the will say "ok jalan" otherwise if they saw something big they will say "ok tepi tepi"...

but the fact is after they rev your car after that only we will know we "kena" or not...they also always "kena" with big2 type off muffler such as SuperDragger, Blitz Nur Spec, Hyper Medallion, Silent HiPower etc after they rev the car..."oh x bising pun ekzos ni...ok jalan"... that time all the "prang prang" already pass them...hahaha

yeah u are rite the chances of a bigger muffler getting stopped are greater than for a smaller muffler coz they will assume that bigger muffler will produce louder sound
but that is not the case it is also dependent on the exhaust piping from front to back
but hell they enforce the rules so what to do
