Or do you not need a CARB EO number with newer cars as long as you have the cat and no error codes?? I'm used to exempt cars so trying to figure out what's up with an E92

They do not have a CARB certification. I would say they more-so look legal but I typically don't comment further then if they are CARB legal or not - for liability reasons.

Largest benefit of them is the fact that it still is "emissions friendly", reduces smell, healthier and smooths out sound.

If you want a legal car in CA, stay stock or stay with CARB friendly mods. I can't recall any downpipe even with cats actually being CARB certified - it would be a near impossible task and lots of $$$$.

Your tune from wedge will clear CEL automatically wont it? And you could get a DP fix to pass emissions if those are your only concerns. At least I think the DP fix is still needed.

I'd have to check with Ken if it will clear it auto. I have a scan tool in the car 100% of the time lol so I could always just clear it. I might reach out to Tiago and see what they charge for the DP/ install and cat fix

It's not carb legal, but when the hood is opened and the tech is looking for catts their their. Will he know their not stock who knows. You could gut your stock cats. Then they would look stock run the cat fix and your done.
Don't know if anyone has ever dynoed 1 or not.

hey guys, just a quick update since the install.
I have had no issues whatsoever.
I also removed my JB4 quite awhile ago as well and have not gotten a CEL. Currently running no tune at all at the moment and still not getting a CEL.

So I would say you will not need any CEL deletes.

I am currently in the process of going from catted to catless (want a bit more noise) so will definitely post up stock dp vs catless dp gains.

I'd also like to mention the dyno pic I posted up I am running an axle back Remus exhaust

Did you compare catless to catted performance difference with a tune?

I have the VRSF 3.5" Catted DP. I went back on the dyno after installation. I gained ~20+hp and ~25+lb ft tq. No smells no Check Engine Light. I am happily surprised with the results because I did not expect such a difference without additional tuning.

How does it compare to catless?

Any update as to catted v catless?

[DYOOS]

I've been pulled over for running a straight pipe (no cat). The sound is amazing and gains were great, but the fix-it ticket wasn't.

I've driven behind/around catless cars and it definitely smells. It also depends on how sensitive your nose is, but regardless there is a gasoline-burning scent - no denying that.

Get a catless DP if:
- You don't care if you get pulled over
- You want the HP gains
- You don't mind the smell
- You want the sound

Get a catback DP if:
- You want to get as much HP while complying with smog regulations
- You don't want any smell

Not an issue here in NZ, perfectly legal
The concern about the smell did hold me back but I eventually went catless and I can barely tell the difference, it's only slightly stronger than a regular car with a cat.
