Dear Guys,
This question has popped up several times!
I wanted to cut off my L/R oval shape exhuast tips on my previous E250 to the "AMG Sport Trapezoidal Shape Exhaust Tips)
This has prompted me to write to LTA to clarify the mods pertaining to modifying your exhaust tips.
According to LTA as long as you do not "touch, weld, drill, etc" on the rear silencer/muffler box is OK with
what you want to do with your exhaust tips.
You may have twin exhaust tips coming out of your muffler, you can cut one or two of your exhaust tips and reroute to Left & Right with dual single L/R or quads L/R.
Anything on the muffler box and before on the exhaust system you will need prior approval from LTA.
This is my email to them & their reply!

Subject: Modification of muffler exhaust tip
Dear Sir,
I understand that changing of the car exhaust muffler needs LTA inspection
and approval.
This I am clear and aware of LTA's policy on car modificadtion.
I have a question to ask pertaining changing only the exhaust tips of the
exhaust mufflers.
If I will to cut off the existing oval shape exhaust tip from my exhaust
muffler at the pipe after the exhaust muffler, replace and weld a
trapezoidal shape exhaust tip at the pipe, is this legal or illegal?
If it's not illegal, do I need to seek LTA's inspection and approval as I
do not do any modification to the muffler box but replacing only the
exhaust tip on the pipe after the exhaust muffler by welding another
exhaust tip on the pipe?
There will be no welding onto the exhaust muffler box but only welding on
the pipe after the exhaust muffler.
Looking forward to your kind enlightenment, I remain
Yours Faithfully

Dear Mr XXX
Please refer to your email dated 12 July 2011.
We would like to inform you that we have no objection to the fitting of
exhaust pipe outlet attachment (by way of welding or screwed on) onto the
original exhaust pipe after the rear muffler so long as this does not
adversely affect the safe operation of the vehicle and the exhaust pipe
outlet attachment is not welded directly to the silencer/muffler. Please
also ensure that the followings are complied with when fitting the exhaust
pipe outlet attachment:
a) the exhaust pipe outlet is installed with sound engineering practice and
must be adequately supported;
there is no modification to the other parts of the exhaust system,
unless approved by us;
c) the exhaust pipe does not protrude longitudinally or laterally from the
vehicle;
d) the exhaust pipe outlet is on the off-side or rear of the vehicle; and
e) the vehicle exhaust continues to comply with the applicable exhaust gas
and noise emission standards
