Nice rides. Now I want to lower my truck.

Thank you for teh Lovely Comments!...........

got bored again..deleted Cats.....

but not the tone i want..it does sound good...but i may try Magnaflow Cats..ordered it waiting to arrive...


comparison of set up..


4.8is
stock mufflers.....
xpipe and eisenmann

now
cat delete+Xpipe+Eisenmann



next...
Magnaflow cats+xpipe+ Esienmann...waiting for arrival of cats

Fraser, I already saw Mike's beast when I had the new rims installed on my e70 last week, his 4.8is is one of a kind...

4.8is and 35d

Mike, theres no stopping now... euro headlights bro...

Mike, did you say "deleted cats"?... as in catalytic converters??? can you do that??

It is actually a Federal Offense to remove any smog equipment on vehicles in 49 states. You can get away with it by replacing, as what Mike is going to do with the Magnaflow, but if you leave it "deleted" you wont pass emission inspection (unless the fool that's doing your inspection doesnt notice it and for some reason the machine triggers accurate hydrocarbon output levels or you slip him $50 for the sticker).

In the old days that used to work but since NJ is now Emissions only for inspection I'm pretty sure they crack down on the emissions part of it because deleting the cat and not having a check engine light is not only step 1 of the job, if you can somehow space out the o2 sensors enough to not throw a check engine light you have to make sure your sensors have passed all readiness tests when the OBD sensor is hooked up.

This is for the guys that say "just reset codes then go through inspection since it takes 50 miles or so for the OBD to throw a check engine light", since although you might not have a check engine light after resetting the lights, you still won't pass readiness checks, which also takes about 3 hot-cold cycles of the key.

In theory, if NJ is truly Emissions only and does not do a visual inspection for the cat, you could pass the emissions test IN THEORY without any catalytic converter at all if you can find the "sweet spot" of o2 sensor spacing. From my VW days, if you only have one cat in place, you should be able to pass readiness tests and not throw a check engine light if you install one of these, and if they do not visually look for a cat

The spacer works so that the o2 sensor is taken out of the exhaust stream and since it "sniffs" less pollutants on the post cat section, the system is pleased and should pass readiness, without throwing a CEL.



EDIT: I do not condone tampering with Federal Emission equipment, however these are things I've learned in many years of trying to avoid check engine lights from glowing on my VW's. I always run high flow cats but essentially the spacer will work the same way as most high flow cats still will trip a P0420 code for catalyst efficiency since they flow much more than stock. You need to space out the rear o2 sensor a bit even with high flow cats in my experience to avoid CEL and still pass readiness.

In a nutshell... Too much fooking work. I heard that the fines imposed are crazy in Jersey also, up to $10k or 6mo in a 6x9 for both the shop and vehicle owner.

I know for a fact that if i am taking my car out of the US to a country that does not have UNLEADED fuel and has only LEADED, my agency issues me a letter, authorizing removal of the cats and proper storage of them in my posession. i can do this only so many days before the departure. i must preserve the letter of authorization, and the documents supporting the removal of the cats, and upon return of the car to the US, the car will be released from the customs pending the reinstallation of the cats, and i must present the customs with papers supporting the cat reinstall...

in PA, they do check the presense of the cats, even though just from the outside, and the OBD is connecting to the state computers and i think, some info is being uploaded to the state... not sure about it though but suspect that the state (big brother) keeps a record of the cars' OBD info...

Well, I made my post a bit complicated, but it's actually probably less work than you realize. Since we only have 1 cat, it should be fairly easy using that 90 degree angle o2 sensor spacer I posted above, it helped get rid of my Check engine light using a high flow cat with high flow downpipe on my old VW, and I passed emission inspection no problem with all readiness tests passed. Without that spacer, I had a CEL even though I had a cat in place since the high flow wasn't showing the correct "flow readings" on the rear o2, aka the exhaust gases weren't clean enough since there were less cells on the high flow cat setup. What I'm saying is whether you have a testpipe (no cat) or high flow cat, I'm 95% sure that you will need to do an o2 spacer to bring the readings within ECU spec and not trip a Check Engine Light, and therefore be able to pass inspection. I'm a fan of high flow cats, however it's been noted that the difference between a 100-150 cell high flow cat and full flow test pipe is really only a couple of hp at the top end, its really not worth the extra smell of rotten eggs from missing the cat and the pollution to the environment for me to run a full out test pipe setup.

The only thing that might need tweaking would possibly be how far in the o2 sensor spacer gets threaded in, however I used mine threaded in all the way and the 90 degree angle alone out of the exhaust stream worked just fine.

The only thing that would be a total buzzkill is if they look under your car for presence of a cat, if so all my points are moot. I'm not due until December so I couldn't tell you as I don't remember from last time.

Dont worry...it made my car smoke a bit i think.....but my Cats are on its way!!!....BOOOM!.....next week will do another vid ...can't wait!
