modify your airfilter would be better,not open pot,but drop in.
iridium plug and change to 9.8mm plug cable
feel more different,port and polish and cam all bla bla bla
if dont want..just use back your original piping size,cut off catcon replace with bullet
change the 4-2-1 back muffler change to direct flow for manual,sflow for auto
shao kong
straight flow is best. don care auto or manual lah. but, dont use too big diameter. for example, 1.5 engine put 3 inch straight flow, sure lose pickup..
bising saje.. tapi tak jalan (like most kancil i see on road). keep stock diameter
enough. unless u put turbo, then 2inch above is suggested.
key point: back pressure is killing the engine power, but losing all back pressure will also kill it. we need the right amount of back pressure to maintain all range torque.
(correct me if im mistake, thanks)
Bro, auto tranny shouldn't go all straight flow. It needs to detain some pressure back so that the power comes at higher rpm. Auto tranny should go for sflow muffler. If straight flow all the way, overall power loss. As for manual tranny, we need to make as negative pressure as we can, the best is totally no back pressure at all. So, i say the best muffler for manual is no muffler at all. Well, depends on people, if you quiet type straightflow, choose proper setup with as few muffler as you can. Choose wisely :)
so, how much backpressure we should maintain so we have torque at all rpm range??...
Bro, we can test it via dyno like kent20 said, or you gotta trust the experienced exhaust specialist as they know what type of mufflers is the best for your car. Just state what power you want such as pick up ,top speed or even overall gain. Just simple as that, but the hard thing is that you need to get someone who is darn good at his job.
hi, i am newbie here too. would like to know is it a turbo car must use a straight flow muffler to utilize its power?
is there any setup for quiet exhaust system suits turbo car? maybe twin exhaust system?
Hi ahren, for fully utilize the built-in turbo in your ride, we should eliminate any back pressure that will occur in your exhaust systems such as small piping size, empty midbox, sflow mufflers and etc. So, it would be the best to understand how much power does your engine produce. By that, we can determine what piping size you should use. Twin exhaust system is also a solution as more pipings give better output and faster exhaust flow. However, muffling effect plays a bit role in silencing the exhaust noise. So, choosing the right bullet or midbox is crucial thingy.

depand what type of turbo u using,
TD04-TD06 exhust setup all different,turbo car wont be noisy one,normaly use 2.5" inlet muffler
no sound one
Remamber 1 thing N/A using straight flow is always noisy then turbo
thanks for 2 sifus help. I think of getting my waja a GSR turbo, wonder if i need to change the whole exhaust system or not.
use back the original GSR Piping that u purchase from the half cut..
if u never mod your turbine,then go for 2.5" piping all follow your waja original way
do not make it ----------------------------------(fuel tank)--------(muffler)

m3power, no need to refiber ler...refibering is more expensive than you getting a new one, else you wanna refiber those big mufflers like Drager. Refibering costs around 200+ for a big muffler. The midbox that i recommended usually can stands 2 year more.
