Mane ade logic camni.

Exhaust setup also involves the extractor design, muffler type (straight flow, S-flow), piping diameter etc. etc. Which in turn is influenced by your intake setup and engine displacement as well.
in fact the size of your muffler tip probably has the least affect on the car's performance

not sure but i've followed alot of car that have modded their muffler to big ones
each and every one of them have no power at all....no pickup at all when they accelerate..the sound very loud only
even my underpower BLM have to break becuz they're going so slow
the ones that are unmod, i can see their pickup is somewhat normal/fast
not sure is the muffler's problem or the driver problem
i've also driven a proton arena with modded muffler..rev until 2.5K RPM also no power...sound loud only
i can basically archive the same pickup with my waja @ 1.5-2k RPM
if u say won't have effect, thn it must be the driver's problem

My car got the tak tak sound d

always happen during cold start or morning..some time afternoon or after awhile of driving also will hear the sound...it is coming front the engine there, dont know whether is it timing belt or what..
Is this tak tak sound normal? recently 1 month back started to have this tak tak sound.
how old is your car already?...how many KM already?
my case, the mech say its the belt problem...yesterday change, the sound did dissapear but have to monitor awhile longer on cold start and when its hot...see if the tak tak sound still there or not
