Who's exhaust smells like rotten eggs?
My exhaust setup consists of the following:
'99 Prelude
2.5" Downpipe
3" Flex Pipe
3" Carsound High Flow Cat
3" Mandral Bent Catback Exhaust
Magnaflow Muffler
I'm sure some of you have the same problem I do. A lot of times at a stop light I get that rotten egg smell. I was hoping that since I went with a high flow cat instead of a test pipe I wouldn't have a problem. Do you guys have this problem with high flow cats as well? Any solutions?

Mine smells like roses. 
My old 92 CX used to get a nasty sulfur smell every now and then. No idea why it did it. I'm running pretty much the same setup on my EM1 now that you are and I haven't smelled anything abnormal.

not 100% whatsoever, but i thought an egg type smell had something to do with the EGR system.. dont quote me on it though.. just throwing it out there.. good luck.

Mine smells like sulfur. I know for a fact I WAS running rich, now I just need to get a test pipe and remove my cat. I ran really rich for way too long.

I was told by at a muffler shop that when you get a rotten egg smell. the car is to rich and possibly the converter has went bad.

Most likely your cat converter is ****....
Go check it please before you break something else...
When the cat gets mess up you will know by a nasty smell or might be something else but most of the time you got a blow cat. Don't take my word for it but make sure!

It can also be from a bach of fuel with an exceptionally high sulfur content. Run the tank almost empty and change brands. See what happens.

My high flow cat had a sulfur smell when it was new.
All it took was getting it nice and hot once or twice and it was fine.

Re: Who's exhaust smells like rotten eggs? (Hella_JDM)
my exhaust smelled like sulphur(or rotten eggs) then it stoppped
reason
cause i blew my cat out completly, its clean nothing left
running rich does that... not good for cats
but i have a great test pipe now, looks just like a cat. the diameter change isnt optimal but for cop issues it should help a bit

That and the smell of open dump makes for an air freshener that only boosted cars have
