Since putting on my Pacesetter LTs with the TSP catted y-pipe I can't pass the e-test. Failed all three tests at load, but pass at idle. I always passed before with all my other mods and tune.

Anyone who has the same y-pipe and passed? Also, what high-flow cats are other people using and passing the test.

What mods are on your car?

I passed '97 standards with:

6.0L LQ4
Stg. 1 LS6 cnc heads
222/224 on 112 cam
FAST intake
underdrive
Pacesetter race headers
Y with magnaflow 55959 bullet cat's

passed easy.

ASM Test
HC ppm - 18 - 242max
CO% - 0.03 - 1.92max
NO ppm - 169 - 2520max

Idle:
HC ppm - 195 - 300max
CO% - 0.09 - 1.50 max

Hot rod standards are listed. its about 35% higher then 97 standards, but you cans ee it would have passed with flying colours either way.

I've got every bolt on possible and tuned. It passed with flying colours as well before changing to the TSP cats. They are very small.

wonder if you could put magnaflows in place?

I based my Y off the TSP one, i fabricated it myself. its got awesome ground clearance, and the cats work like a champ

I know a couple guys in KW that passed with the TSP catted y and have a cam. Stock cam you should be able to pass with it. How old are the O2 sensors, spark plugs?

Fresh oil change?

What grade of fuel did you run? Can you run something lower (ie: 89 or 87) at least until you've passed the e-test? High octane fuel can be a killer for the sniff test.

beaSSt

Oil's fresh, plugs new, no trouble codes, etc.

I'm going to try leaning it out around 2000-2500 rpm and the gas line antifreeze / methanol addition.

TSP now says that these cats are not e-test friendly but I must be running a bit rich at the load test.

I did have 87 octane in it as I failed a couple of years ago with Sunoco 94, switched to Shell 87 and passed like a champ.

If all else fails it looks like the magnaflows could be the answer. I'd rather do that then just give McGuinty $450!!!!

I am gonna keep watch on this one, as I amy move to Ontario with my cammed 224 112 car (no cats), will most likely try the magna flows.

My car passed magnaflow cats no muffler you wana get your car really hot and don't put fresh oil in it a buddy of mine works at a drive clean centre says new oil is bad cause it actually puts out toxics to make it fail older the oil the better cause all the toxics are burnt off anyways ya the magnaflows sound great and pass the e test and my car runs rich on the motor cause I cruise around on a nitrous tune

beaSSt

Which Magnaflow cats do you use? If my leaned out tune and alcohol blend don't work replacing the small Carsounds with proper Magnaflow cats is the next step I think.

VIPERSLYR

The cats are 3 inch highflow magnaflows off the shelf from a local napa

Make sure you get those things really hot before you go. They are far back so they don't heat up as easily as stock ones.

since its an ss register it as a collector car i know in kansas collector cars dont need emissions.

Doesn't work up here. Unless you've swapped to a motor that wasn't available in the car originally you have to meet the #'s for your year.

91ZLS6 used the Magnaflow bullets. They are real small but do the job.

thanks for the info -- you wouldn't happen to have P/N?

keep us updated on how you pass...I think I may have a bit of an issue as well, my car stinks, but I think that could be a combination of oil leaking onto the Y-pipe, the high flow cat, and the 91 octane gas...I need to get my tests done in about a month or so...

just a side note...does it make a difference for etests (good or bad) if you leave your cutout open? (assuming the cutout is place a little further back, like just over the axle area)

Hmmm, open cutout? It would probably pass ..... it might actually pass "too good"?! (ie: such low emissions, it would look suspicious!). For that, you'd need to KNOW SOMEBODY at a shop who would allow you to do it. Otherwise, first thing a tech is going to notice is the gigantic exhaust "leak" you have, which is an instant FAIL, regardless of what comes out the tailpipe .

I've never heard that new oil has toxins in it that will cause a fail???! I sort of question that one. I know that an old truck I used to have in college (1990 1/2 ton with a 350 throttle body motor) would burn through a litre of oil every few days (SOMETHING was going down the sh!tter, that's for sure!) so it was essentially getting a fresh "oil change" every couple weeks. Somehow, that truck passed its e-test, and it wasn't even what I'd consider "borderline"?!?!

beaSSt

OK, getting ready for a re-test as I just got back from a long business trip.

Going with shell 87 gas, couple of pints of methyl alcohol and going to lean it out in the load test rpm range with my handheld.

I guess I'll look to the low voltage end of the 02 sensors -- around 850 mV at the load test rpm.

any other suggestions?

I tried it. It didn't work I still failed w/ cutout open.


What portion did you fail on?

Send me a PM too!
