Longtube headers and emissions testing

[Greg Hazlett]

As long as you stayed out of boost/WOT for the trip to/from the inspection facility I am 99% sure you would be ok.

OK Greg. Im taking all this in lol. What I don't like about going without cats though is it is too loud, and tends to smell. So, I really would like to keep them, if possible

 

[Greg Hazlett]

True but you learn to live with the smell and the noise can be toned down depending on the mufflers.

understood Greg. But i am considering Kooks, with the green cat H pipe option. It sounds like a good set up.

I emailed Kooks directly, and they said that the starter and or the transmission would come out with the headers installed, which is contrary to what Ive read on forums.
Also, if I install Kooks headers on a hoist, im wondering if the K member will have to be dropped.
Do you have any experience with these situations ?

 

[Greg Hazlett]

The only LT's that I have read about that does not require the K member being dropped are JBA but I cannot verify as I have never used/installed JBA; other than JBA to the best of my knowledge the K member needs to be dropped to install the LT's.

[...] ...he said I don't put enough miles on the car to be concerned ( I drive it about 1000 miles or less a year)...

But you think about 25,000 miles a month, right? That thousand miles must be extremely joyous, to make all the foofaraw worthwhile. You need a Smart Car.

No need to drop the k-member for the American Racing Headers. Actually the only longtubes that I know of where you do need to drop the k-member are the Kooks 1 7/8.

Those equal length primaries make their headers very broad.

UltraKla$$ic installed his SW without dropping the k-member also.

Non-foulers with the o2's on! Passed for me and I have no cats.
Tell them to turn the rear o2's on and get yourself to vatozone and get two packs of these.

Then do this...

Again, passed after a drive cycle with my rear o2's on in the tune and NO CATS.

Thanks for the info bro ! I am not sure what you meant by passing a "drive cycle" I have to pass plug in OBD II testing so as long as it doesnt throw codes, Im ok.

Ford Motor Company Driving Cycle

Description of OBDII Drive Cycle
The following procedure is designed to execute and complete the OBDII monitors and to clear the Ford P1000, I/M readiness code. To complete a specific monitor for repair verification, follow steps 1 through 4, then continue with the step described by the appropriate monitor found under the "OBDII Monitor Exercised" column. When the ambient air temperature is outside 4.4 to 37.8°C (40 to 100° F), or the altitude is above 2438 meters (8000 feet), the EVAP monitor will not run. If the P1000 code must be cleared in these conditions, the PCM must detect them once (twice on some applications) before the EVAP monitor can be "bypassed" and the P1000 cleared. The Evap "bypassing" procedure is described in the following drive cycle.
The OBDII Drive Cycle will be performed using a scan tool. Consult the instruction manual for each described function. NOTE: A detailed description of a Powertrain Control Module (PCM) Reset is found in this section, refer to the table of contents.

Drive Cycle Recommendations:

• Most OBDII monitors will complete more readily using a "steady foot" driving style during cruise or acceleration modes. Operating the throttle in a "smooth" fashion will minimize the time required for monitor completion.
• Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.
• The Evaporative Monitor can only operate during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to minimize "fuel slosh".

WARNING
STRICT OBSERVANCE OF POSTED SPEED LIMITS AND ATTENTION TO DRIVING CONDITIONS ARE MANDATORY WHEN PROCEEDING THROUGH THE FOLLOWING DRIVE CYCLES.
For best results, follow each of the following steps as accurately as possible:

Preparation1. Install scan tool. Turn key on with the engine off. Cycle key off, then on. Select appropriate Vehicle & Engine qualifier. Clear all DTC's/ Perform a PCM Reset.Bypasses engine soak timer. Resets OBDII Monitor status.2. Begin to monitor the following PIDs: ECT, EVAPDC, FLI (if available) and TP MODE.
Start vehicle WITHOUT returning to Key Off.3. Idle vehicle for 15 seconds. Drive at 64 Km/h (40 MPH) until ECT is at least 76.7°C (170° F).Prep for Monitor Entry4. Is IAT within 4.4 to 37.8°C (40 to 100° F)? If Not, complete the following steps but, note that step 14 will be required to "bypass " the Evap monitor and clear the P1000.Engine warm-up and provide IAT input to the PCM.HEGO5. Cruise at 64 Km/h (40 MPH) for up to 4 minutes.Executes the HEGO monitor.EVAP6. Cruise at 72 to 104 Km/h (45 to 65 MPH) for 10 minutes (avoid sharp turns and hills) Note, to initiate the monitor: TP MODE should =PT, EVAPDC must be >75%, and FLI must be between 15 and 85%Executes the EVAP Monitor (If IAT is within 4.4 to 37.8° (40 to 100°F))Catalyst7. Drive in stop and go traffic conditions. Include five different constant cruise speeds, ranging from 40 to 72 Km/h (25 to 45 MPH) over a 10 minute period.Executes the Catalyst Monitor.EGR8. From a stop, accelerate to 72 Km/h (45 MPH) at 1/2 to 3/4 throttle. Repeat 3 times.Executes the EGR Monitor.SEC AIR/CCM (Engine)9. Bring the vehicle to a stop. Idle with transmission in drive (neutral for M/T) for 2 minutes.Executes the ISC portion of the CCM.CCM (Trans)10. For M/T, accelerate from 0 to 80 Km/h (o to 50 MPH), continue to step 11. For A/T, from a stop and in overdrive, moderately accelerate to 80 Km/h (50 MPH) and cruise for at least 15 seconds. Stop vehicle and repeat without overdrive to 64 Km/h (40 MPH) cruising for at least 30 seconds. While at 64 Km/h (40 MPH) , activate overdrive and accelerate to 80 Km/h (50 MPH) and cruise for at least 15 seconds. Stop for at least 20 seconds and repeat step 10 five times.Executes the transmission portion of the CCM.Misfire & Fuel Monitors11. From a stop, accelerate to 104 Km/h (65 MPH). Decelerate at closed throttle until 64 Km/h (40 MPH) (no brakes). Repeat this 3 times.Allows learning for the misfire monitor.Readiness Check12. Access the ON-Board System Readiness (OBDII monitor status) function on the scan tool. Determine whether all non-continuous monitors have completed. If not, go to step 13.Determines if any monitor has not completed.Pending Code Check and Evap Monitor "Bypass" Check13. With the scan tool, check for pending codes. Conduct normal repair procedures for any pending code concern. Otherwise, rerun any incomplete monitor.
Note: if the EVAP monitor is not complete AND IAT was out of the 4.4 to 37.8° C (40 to 100° F) temperature range in step #4, or the altitude is over 2438 m. (8000 ft.), the Evap "bypass" procedure must be followed.
Proceed to step 14.Determines if a pending code is preventing the clearing of P1000.Evap Monitor "Bypass"14. Park vehicle for a minimum of 8 hours. Repeat steps 2 through 12. DO NOT REPEAT STEP 1.Allow the "bypass" counter to increment to two.​

Thanks Gremlin !

Thanks for the info bro ! I am not sure what you meant by passing a "drive cycle" I have to pass plug in OBD II testing so as long as it doesnt throw codes, Im ok.

Drive cycle is when your vehicle performs a series of tests to make sure all the emission equipment goes to ready status. If it says not ready you fail....drive cycle is driving at a bunch of different speeds and times etc...I have ford drive cycle here ill forward it.

OK Qwk. Thanks !

 

[fdjizm]

I failed the first time because I didn't do a drive cycle, the computer says the o2's aren't ready or something, it took me like 30 miles to complete a drive cycle, went back with no other changes and passed.

Do you have something to monitor the drive cycles?

 

[skwerl]

Well no wonder I was never able to clear the P1000 code. It says that the EVAP monitor will not run when the ambient air temp is between 40-100 F*. I live in Florida, temps are between 40-100 about 362 days per year. Luckily my tuner was able to eliminate the code permanently.

What do I need ?

 

[BadHabit2Break]

What do I need ?

There are different apps for smartphones that work great.

If you are on Android, then there is Torque. You will need to buy a BT adapter to connect to the ECU.

If you are on iOS, there is Dashboss. You can buy their BT adapter and download the software from the app store.

Both work very well.
