Shouldn't be expensive to fit a Jazz muffler onto EK sedan.
It's mainly about the length of the muffler body. Provided
that it'll fit within the area of the exhaust hanger bushes and the
lower control arms, you should be fine.

Just make sure you get the piping mandrel bent and not
press bent as the latter is simply sh*t. Also i'm not sure
whether the EK sedan has a rear sway bar or not. If it
doesn't and you intend to fit one later on, make sure you
tell the exhaust joint to make enough room for this when
you're getting it done.

All up should take less than an hour and less than $150 all
up. I got mine done for $120.
