URD 02 Cat Simulator and Inspection. HELP

[DatSRBoi]

Im thinking about gutting my Cat with a straight pipe soon. Hoping it will help solve soon issues Im dealing with..... Does anyone have the dirrection for it to the solara? Because on their site theres no option for the solara so that is kind of bad.. SO if anyone got the exact direction that would be nice. Also which optin did you choose when buying it for which car or is it all universal?

Then I went with my friend to a state inspection a few weeks back. He did gut out and ran a straight pipe too. Only problem is he failed the inspection. It was something with an exhaust below pressure and 02 mafunction???? He said he got a simulator on that thing and it sitll did that........ Has anyone with the URD 02 cat simulator pass inspecition or did they cheated too with hook up?

Also where did you tap yours at?

I bought a universal one it was cheap... gutting the cat was easy

[trd4life]

i got mine from casperelectronics.com , use the one for the supra. its cheaper than urd as well.

gutting the cat without taking off the y pipe is a bitch cause the cat is welded onto the y pipe so you cant completely take off the cat to gut it. just buy a high flow cat and have it welded on OR if you dont care about inspection have a straight welded in place.

catco cats are nice and cheap from summitracing.com or if you want to spend the money get a random technologies.

I had the JPP setup, and gutted that easily

oh yeah.. casperelectronics.com is some dude who takes toys apart to make other toys... is that the correct http?

um if your having cat problems toyota covers them 8years 80kmiles and there isn't a way to get the car to pass inspection and if you have an inspection to pass i don't advise gutting a cat as you are responsible for the 10000 dollar fine from the epa if you get caught.

The EPA only fines shops who disable pollution control devices, not individuals, it is more a threat than anything. Anyway, I run a gutted cat and oxygen sensor sim and got through our DEQ (department of environmental quality) test with no problem. The inspector doesn't even open the hood, he just plugs into the OBD2 port and checks status. The O2 simulator keeps the ECU in the dark about no cats in my JPP exhaust.

Well I wanted to free up flow to put less stress on the motor. Thats the issue for me specially in texas with the hot weather.

My bad. I didnt mean to say gut the cat. I meant funning a straight test pipe basicly. The inspectore doesnt look under the hood and all that stuff. But the thing that my friend failed on was the OBD2 test part pulled it up. And his car had no CEL or anything.... Did any of you guys pass yours?

So I can use the supra 02 SImulator and be ok right? and run a straight pipe and completely remove the Cat? Im talking about straight up running a weld on straight pipe with that simulator..

So who passed the OBD2 Inspection part with this and a straight pipe?

I bought Gabe's old custom y-pipe (cat delete) and it really brings the middle of the RPM range to life. The stocker y-pipe is the bottleneck in the exhaust system.

Like others said, easiest route would be to replace cat with straightpipe. I just paid with cash, no reciept and the mom/pop exhaust shops would do it no problem.

Is that Y-pipe pipe the one with the unequal length piping from the V6 exhaust manifold?

I always wondered if the unequal length was worse than the equal length because I remember when the Y-pipe issue started several years ago, a Nissan aftermarket fabricator, I think it was Cattman, used the unequal length on his Nissan and had really good results.

Yes, rear bank length was only about 6" or so. The performance was good, although I did notice a tiny bit less low end (< 3k RPM) torque. I guess the one con was exhaust note sounded sort of peculiar.

Well I know it gives power... But the thing was. Did you pass the OBD2 computer part of the inspection.

St. Joseph county doesn't have any emission inspections, along with many other counties in Indiana. I had a current code (CEL) from the downstream O2 sensor, so I would have failed an OBDII test.
I was using the redneck fix, electrical tape over the CEL, didn't get a simulator yet.
