Arh headers with cats wont pass emissions test?

[stoli]

But....in FL we don't have to deal with this crap

:amen:

The smell isn't nearly as bad as you think. Plus, are you planning to be stopped in traffic with your windows down all of the time? Smh, honestly, that is the weakest excuse that I have heard. I understand the emissions issue but smell, I say grow a pair...

I really think that most people that complain about the 'smell' haven't actually been in properly tuned car w/out cats and have a misconception of the scent of raw power. ;) Most think it's going to smell like a poorly tuned diesel or a car burning a ton of oil.

What?

I guess I need to send in a request for a revision. I was unaware my car wasnt properly tuned. Thanks for the heads up. I will ask for the no burnt oil/diesel smell mod. Is it a free update or is there a $100 up charge?

Or the car just plainly sounds better with the race cats in. Im extremely happy with my numbers. I highly doubt I'm down 10-20hp as some claim either. I've personally swapped them out twice. Only difference I noticed was the car actually seemed to run better and cold start volume was reduced. You claiming you cannot smell raw fuel coming from a catless car is bogus.

sound is subjective not factual. My claim is not bogus. Tune can effect what you smell. Might want to be better informed before you basically suggest people are liars.

It was free during the week of Christmas, I guess you missed out.

A more lean running tune will have less smell. Its not untrue. Id be willing to wager a custom in person tune would be different then an E tune. Very few e tuners will give an aggressive tune that way. More smell is from a richer tune. There is no need to have such a chip on your shoulder especially when you don't know what you're saying.

You didn't mention anything about the tune affecting smell. Stoli did. I said you saying you cannot smell raw fuel is bogus. It's a very distinct smell that burns the nostrils. Do you know why that is? As I stated earlier they are noxious fumes. As in harmful to your health. I could almost instantly smell the difference when I switched to E85. I was stating an opinion on what I preferred and my experiences. You however were using grade school puns to establish some kind of alpha male status of being catless. That is where I found humor and fallacies in your statements.

I got the FlexFuel tune also. Its been great so far. The corn has a sweetness to it. Reminds me of a diesel running vegetable oil.

Yes i did. I also said ive rarely ever smelled anything for the most part and when i have its been on the faint side. Its no exaggeration. Ive owned dozens of catless cars over the years. My cars have always ran on the very aggressive side of tunes though. I also included either some have a sensitive nose or they are a candy ass. Its not grade school puns. Some people legitimately have a sensitive nose. Some are just wussy boys. I didnt state which you were. Why you felt the need to be that way was unwarranted. Had i called you a wuss puss i could get that. There was no sophistry in my post.

That escalated quickly. Anyway, it's a personal preference. Unlike some people who choose to have catted for inspection reasons, I am not obligated to, and I have no emission regulations. But that doesn't mean I would like to smell like fuel, also I would like to avoid any raspiness in the sound (or at least keep it to a minimum) which is usually associated with going cat less. I've read a lot of threads here about catted vs. non-catted, and for the power difference it doesn't seem worth it to go cat less, but that's just my personal opinion.

According to my shop my 93 tune will pass the OBDII check in MD with my catted headers. We'll see. If it doesn't I'll have to get creative.

After reading some of these header threads, I'm not sure I want to bother dealing with the possible headaches of passing emissions/inspection, which kinda sucks...

For real. Im kinda pissed after reading this thread. Was looking forward to getting headers, but they will be a complete waste of money in 4 yrs once emissions comes around.

If you really want headers go with the Kooks 1-3/4" primaries and Green Cats. I just had a local guy install this setup with the stock tune and still has no CEL. I don't know if his monitors are 100% ready but so far no CEL.

With more driving there is a good chance of that happening. If it does throw a CEL then we can install these between the rear O2s: JDM O2 EXHAUST BUNG EXTENSIONS NON FOULERS FOR OFF-ROAD USE If that doesn't work then we are SOL...

Like others said, there is no guarantee. To ensure the car will be able to pass when the time comes stock manifold with the stock cats is the only sure fire way.

A lot of mis-perceptions cited in this thread about the testing and what will work/not work. In the following, I hope I can add some clarification.

All modern automobile ECU's by OBD2 standards, employ readiness monitors. The ECU is continuously performing tests of emission components and is programmed to turn on the CEL if a test fails. If the test continues to pass, everything is fine and no CEL. All good so far, but the purpose of the readiness monitor is to state if the test has been performed. So, for example, if you live in a state that does SMOG testing by connecting to the OBD2 port, there are only two things that are being checked. No readiness monitors are on (indicating that an emission components test has not yet been performed) AND that there are no CELs. The OBD2 connected test CANNOT determine if the rear O2s are on or off, but IF they are off, either you will have a failed but suppressed fault code, or the CAT readiness monitor will not be set and you will fail the inspection.

Many tuners readily have access to turn off the rear O2's and further, they can SUPPRESS the CAT (or virtually any other code) from illuminating the CEL. This may give many the FALSE sense of security that all is good. To the best of my knowledge, tuners DO NOT have the ability to muck with the readiness monitors so currently there is no programmatic way around this.

Many modestly priced code readers will now also report on the state of the readiness tests. This is cool insofar that you can plug one of these code readers in and know whether or not you will pass this component of the SMOG check. You must have NO codes, and all of the readiness monitors must be set (indicating that the internal tests have been performed).

My $.02 on the aftermarket headers/cats based on our rather considerable emissions testing with the Boss 302 (wideband-controlled) Coyote engine. I'd estimate the MOST aftermarket CATs are not near-enough the OEM density/quality to pass the internal CAT testing and would therefore represent a fail condition. Our experience was with Kook's latest (at the time) "green" cats. In fact, Kook's worked with us and created a system with (2) of the green cats in series per side - 4 cats total, and this worked for us initially but failed again within a year.

I'd be (pleasantly!) surprised to learn of an aftermarket header/CAT solution that would work in compliance with late model (2012+) Mustang ECU which seems to be extremely adept (unfortunately) of detecting sub-OEM quality CATs in lieu of the OEM CATs.
