I do my exhaust in Bercham area. Forgot the shop name but speciallized in turbo car. I go there feel so small coz mine only NA 1.5 car, they all turbo edi.. big2 intercoller on the bumper... ooo...  . They do job very fast. 30min only all done. Change piping and spiral bullet...

but how do i take out the old radio?do i have to open up the whole panel?cant seem to figure out how..its the old blaupunkt cassete player..

general guideline is, if muffler is straight-flow, then the hole at the input all the way till the output on the muffler is a straight-line. that was why last time when we ask u to check ur muffler, we ask u to poke a stick through 

for S-flow, usually the exhaust gas has to travel in a S-shape manner between input and output of the muffler. mind u, usually for S-flow it is not a pipe bent into an S-shape, but usually straight pipes connected by 2 chambers (or rooms if u like) and thus creating a S-flowing path for the gas to travel. picture below is an example of the many variations lor. good for increasing gas velocity, but bad due to backpressure.


for the mugen twin-loop type, if not mistaken, is bent pipes, but i could be wrong (havent seen a cross section of mugen's twinloop yet)

got de, example, i realize that WiSE stock straight-flow muffler is not noisy at all.
but i dont wanna buy those la, not "original" from the rest on the street
btw i'm seeing more and more of these designs from local manufacturer. i think the tabung is to reduce noise?
but dunno how much that tabung helps, if at all    i like to call these type the "lan pha" muffler
