I guess that I don't want to fool someone into thinking it is okay, I actually want it to be okay. When I read the description of the catted speed factory headers I got the impression that this was the case. Apparently not.

Actually, if you turned off aka "Not Ready" your O2 sensor, some state will not pass the emission... EVEN they don't do visual checks.

He is mostly talking about moving or replacing with a non factory cat. If you used a catted header and stock everything else you would have multiple cats. Still cleaner emissions than 90% of vehicles on the road and no CEL.

Eh, do some research. It does vary state by state but obd2 test states generally pass anything that doesn't have a CEL. There are certain parameters that will pass and not trigger even the state OBD2 scanner. You are allowed to have a certain number of systems as "not ready" and still pass. It is easy to pass a car when they do the obd 2 test only.

So it is accurate to say that only the factory cat is acceptable to the state no matter how it actually functions?

[Summerwolf]

No. There are loads of exceptions.

So TLDR; get aftermarket header at your own risk. Read the state emission and law. Cuz where Summerwolf lives, he/she can get away not having a cat and tuning it out w simple plug in OBD2. Where I live, they do both OBD2 & visual. If they see "Not Ready" in any o2 sensors, they will not pass.

Are the speed factory catted UEL headers one of them?

You would have to check with NM emissions laws as to what they require to pass a car.


In my state I can run catless so long as no codes were thrown when they scanned through the OBD II port.

How many people are running this header with a complete exhaust system on the stock map? I currently have a Perrin 2.5" resonated catback mated to a Fujitsubo decatted dual resonated front pipe and have been thinking for a while about getting this header to go along side this set up. The thing is I want to avoid remapping for warranty reasons, last time I had my car on the dyno the AFR looked nice a healthy.


Another thing is noise, does the volume increase much with the header attached to aftermarket exhausts? I love the level of noise now, I wouldn't want it to get much louder.

I was happy with the sound level before getting mine too (axle back and catted front pipe), but after getting this header, it doesn't sound much louder on the inside of the car, but it definitely sounds louder on the outside, in a good way IMO. I'm very happy with it. I am using OFT though, but I doubt that changes the sound of the exhaust.

If your modifying your car and worried about warranty. You're doing it all wrong. Even w/ a catted header. It will throw a CEL and your car will run like shit w/o a tune.


To answer your other question. I had this header with a full perrin exhaust and I loved it. It was deep and didn't sound raspy.

Thanks for your input guys

Just ordered this along with the resonated catback for my 2.0. wish me luck

I'm leaning towards getting the catted version with an AVO front pipe and my Perrin 2.5 overpipe and catback. Still need to get an OFT. Trying to avoid spending 1k on it though. hopefully another used one pops up on the FS section
