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.

 

lol make sure a dead animal isnt laying up in that ****,

 

if it smells like eggs...doesnt that mean u got some good gas?? i heard this once..not sure if its true or not

 

mine never smelled like rotten eggs, but reeked of fuel all the time. deff not ozone safe.

Same here. I love that smell. Everyone else who comes in my car is like WTF??!

 

lol. mine has gagged a few people too. Usually the ones who begged me for a ride in it. Then i tell them eithe sit back and quit complaining or start walking. I didnt like to waste my gas that much

 

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!

i love teh smell of cam2

 

rotten egg = bad converter (on a stock car anyway)

 

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.

 

Mine smells like burning wax

 

I believe that is a converter burning up, especially if it is new. My rx7 did that until I took it off. It was a 2.5 inch hi flow cat. POS.

dude...i have that smell as well...wtf?

 

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.

 

i was always told rotten egg smell = dead catalytic (sp?).

 

its the high sulfur content in the pump gas. same problem with new cars.

 

my exhaust smells ******* great . i love c16....

 

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

 

110 + no cats = i smell power

 

My exhaust usually smells like sweet cherry flavored vodka


Gotta love 117 octane!!!
