bro normality......
another thing i 4got to ask you is...
my stock muffler is 1.5", the hot bit 1 is 2.0"
will my car loose power?
coz i did come across in the forum tat a better size to upgrade to is 1.75"if my can upgrade to 2.0" n no problem then i will buy from you....
rm100 oni....
where else can get....:regular_smile:

muffler, you must always remmeber this. flow and velocity. having a big big pipe no doubt will have better flow but you may lose velocity. just like our water tap. u buy normal water hose, you can see the water spray out that force. whn you tried to double up the pipe size, thn u will see the water spray out in lesser force.

there is a big debate on auto car should use sflow or straight flow. no doubt on teori, the straight flow was the one but i dare to GUARANTEE you, if u use straight flow on auto,surely habis... your car sure lembik at low band power. high fc and make suffer to drive. even my turbo also suffer the same issue. i've done it twice, proven twice so who come n tell me auto shld use straight n wun suffer lose power, ask him go fly kite.

since your car mostly standard. no advisable to upgrade the pipe size. let it be until you really mod alot on your engine. actually changing muffler dun really gain much power. more on the sound only. but of course throttle do feel lighter.

Oops......
1 last question....
normality bro....
the hot bits exhaust can fit directly to 4g15 w/o any alteration?

you may wan to elaborate the meaning of alternation. most of the muffler can fit into any car. just the inlet position may or may not in same location as your stock pipe. mostly they dun. but this is not a big deal la... those muffler guy will know how to weld it up

 

[normality78]

4g61t in my iswara......keep P&C la....later nobody wanna chiong me...sien la...

anyway...whats the difference in exhaust brands???

performance vs value-for-money??

put so expensive muffler for standard engine??? makan minyak? kuda ada naik ke??

GAME PLAN!!!!!

as i mentioned, if by changing muffler only, its more on sound thn power. but thn get the muffler wrong will result lose power and high fc. mainly take note on the inlet size. for any stock na, dun go more thn 2". else u will hear all the sound only but kereta tak gerak. whahahaha

 

[normality78]

i not sure bout the standard piping size...
but for standard 4g15 i heard its best to use 1.75" la....
i've changed my piping to 2"....
feels kindda sluggish in low rpm...
mayb its the engine characteristic....dunno la....

bro, i think 2" is too big for normal street use on stock engine la. as i mentioned, velocity. no doubt u will gain frm mid range till high range rpm but thn u still loose the streetbility. its not your engine characteristic

 

[normality78]

[calvin9683]

hmm...
i've asked another 4g91 user....
i presume he din change his piping la...
he oso says power comes after 4k rpm wor....
also the same as i read at 4g91 forum....
heehee.....

actually i dun really get to test the diff between ori piping n 2" ones dat i changed...
coz dat time after transplant....they din fix the piping n extractor properly...
end up i drive up to nilai consuming full tank of petrol....
went n get it chacked in nilai....then the guy say not connected properly....
n i also thinkin of changin the piping....
so do it at one go lo.....heehee.....

[alexklg]

Ashween, my friend told me that he might be able to put up with us. If we want to stay over also can. After TXN or TT come back also can. I don't mind either one. But stay overnight, have to come back early, need to reach jb around 2-3pm. So maybe 9-10am have to leave.

Which one you prefer?

Come back straight or stay one night?
