hi,

I just did my 4-2-1 extractor in wai heng exhaust shop (erm....in puchong location near tesco. but the shop name how come show as Xin exhaust? they wear wai heng shop T-shirt wor) last friday and change the muffler.

I am not very happy with the muffler lar....

last time I used the spoon N1 damn noisy. they recommend me to take the no brand but a bit looks like S flow (but still straight flow muffler).

after change the extractor, I am too excited and forgot to test the muffler...
