hai bro...i drive caldina NA 2.0...my current set up is ;

4 IN 1 (4-1) extractor costume (catalytic deleted)
downpipe ORI
mid catalytic converter beside mid box deleted...change to straight steel piping
mid box ORI
S-Flow muffler
piping ORI

my problem is...my muffler suara macam mau PECAH....if start to accelerate...no bassy sound....whats the problem ?
should i replace my straight piping (coz delete the catalytic converter) to swirl bullet to reduce the PECAH sound and get the bassy sound by my muffler or any other suggestion/recommend ?

i'm glad to come to your workshop...but sadly i live in Sabah...hurm...anyway thanx in advance bro...
