If you'll notice, most of us that have "stinkin' cars" have a bigger cam...the overlap at idle dumps a little raw fuel into the exhaust making the much stronger smell. You guys running catless with the stock cam don't know what strong fumes are.....

If I sit in traffic too long I almost get dizzy

Yep, it stinks just like an old 1st gen would!

haha...well that makes me feel better about my cam. Must be a good one since my car stinks like a ****!! hehe. So the fuel smell is mostly due to the cam specs? No way to tune it to smell any better? I mean...Im not going to go to rapid and say..Please tune my car so it doesnt stink.. Im just curious.

If the sound doesnt warn the slow people that its not an everyday thirdgen...the smell sure will !! haha.

I love it.

Could (or does) this also cause flames to shoot out the exhaust when you back off suddenly at high revs (especially with dumped TDs)?? Or would that take a cam way too radical to even idle, or be streetable??

doesnt the cam add to most of the smell? Seeing as though with a cam you have more unburned fumes? Or am I wrong. My friends T/A didnt stink till he got his new cam and now I refuse to drive behind him.

It is like someone stated before - the valve overlap causes most of it as it scavenges the exhaust out and may take some fuel with it.

I have a cam somewhere around 238/242 .614/.623 on a 112* and it smells pretty damn bad. We had to up the fuel on idle though to keep the pig running. My centermount tips are black and much like someone else said, walk behind the car and you'll smell like exhaust for the rest of the day

I never noticed any smell until I put my cam in either. If I stand behind my car with it running, it will make my eyes water. Just sitting in traffic, there's no problems.

My car would do that with the stock cam. When I went to the track, I would take my muffler off because it was flanged, and everyone would tell me that they could see fire shooting out from under the car. Since that flange was directly below the gas tank, I opted to stop doing that.

i found if idle is richened up the smell goes away, not completely but definitely noticeable....i believe the smell is caused by an incomplete combustion cycle, to little fill air not enough gas...unfortunatly after a car is tuned the PCM will command a ratio of 14.6:1 in closed loop, to get a reduction in smell, idle needs to be around 13.8:1 or so.....my .02

Burn your eyes? Try running some 108 leaded VP C12 and then come talk to me.

How about 100% methanol for a good eye-burning experience

The previous guys are right, the aggressive overlap cams produce the "stink". I did the stock cam to F13 back to stock; no stink with the stock cams.

I hate it! It is something that cannot be tuned out. I have been thinking about some kind of cats.

Mine stinks, in closed spaces. I run a lean idle due to the 10* overlap. But hey, that's where it likes it. No idle, surging or other part throttle issues whatsoever. Unfortunately, smooth running and non-smelling don't always go hand-in-hand.

Perhaps some people shouldn't spend so much time snorting exhaust fumes and just drive the sucker...

It actually bothers me in traffic and when I let the car warm up a bit when it's cold. It will literally choke me out.

i don't think anyone else has mentioned this, but what you are smelling probably isn't gas. the magnaflow catback is stainless steel. stainless steel tends to smell really bad the first few times it is heated. it has a coating on it that must burn off and may take a few days and maybe 100 miles to do it. i can vouch for this first hand as my car suddenly smelled bad as soon as my stainless cutout was put on, but went away completely 50 miles later.

what you're smelling is likely the newly installed magnaflow catback, not gas from the ORY. the gas fumes aren't enough to burn your eyes with an ORY, unless you're idling in your garage with the door closed like tom from office space...but he was trying to kill himself because he got laid off.
