Muffler water drain holes

[dom14]

Just putting it out there
but I think that any vehicle
operated in Vic on
a Fire Ban day is required
to have 100% of
the exhaust gases to
exit the system via the
tail pipe.
If you have holes in the
muffler it would be unroadworthy
wouldn't it?

I don't think weep holes are illegal. Many stock muffler designs seem to have it.

Just checked my new exhaust system that is sitting in my dining room and the muffler has no holes in it at all

You can't eat without having the new muffler next to you?!

Start saving for a new free flowing muffler/hotdog whatever you want to call it.
Pointless trying to repair it unless funds are tight.
I good exhaust is better on your tune and fuel figures to.

Yes. I learnt it the hard way to find out few of my engine hiccup issues were partially related to exhaust leaks from flanges near the exhaust manifold.

Are they noisier than the stock ones?

If your car is a turbo diesal just remove muffler altogether and put a hot dog whitch has no restitions or replace with pipe same size i took my mufflers off my GU 4.2 turbo spools up better an engine runs better i know of other people who have done the same and get better fuel as well//hope this helps.

Wouldn't that cause excess noise? How do you address the noise issue?

Turbo acts like a muffler.

Tested this when we fitted the turbo by starting the GQ with the turbo bolted on but with no exhaust pipe attached. I didn't believe it either until we did it.

No kidding! I'll need to do some homework on that. I'll go turbo eventually, but first need to go EFI.

Turbo breaks up sound waves, result is lots less noise.

Yeah, so the excess noise I hear from lot of turbo charged cars is from blokes messing with the exhaust to make extra noise??!!

there's legal and nearly, probably not legal noise your quoting.
more likely cheap fleabay and then just cheap what ever

I parted with a GTR skyline last year and trust me,
If I took the turbo's off it and left the same 80mm pipes with large cannon etc It would of been 3 x as loud.
at 4ooo rpm it was surprisingly quite, you could actually tell when the turbo's were cutting in to break up the noise.
don't ask what it was like at 8000rpm, different horses for courses.
(short answer fun fun fun 2x garretts & huge induction noise also).
sob sob.
