Has anyone run these? They’ve been tested on RT’s without CELs. I have a modified top end and a custom tune. I’m concerned that if I do get a CEL, that I won’t be able to pass emissions. Currently my tune is dialed in and I pass emissions. I don’t want to drop a good chunk of change on something I cannot run through emissions.

I have them on my R/T

It does trigger a code here and there but we’re talking months in between.

I believe the problem can be remedied with high flow cats

Hmm. How long have you had them on? Do you have the cats with the resonator? Have you passed emissions with them?

Well, here in CA i have 5 more years for smog.

Yes i have the same pipes, 3”. I did remove the resonaters eventually because..i....um....damaged them lol

My car probably only throws a code when cruising at highway speeds for a long time. I mean i put a lot if miles but i only get the lightevery few months.

Also to note....when i removed my cats and started the car with open shorty headers, the damn thing didnt throw a code either

Definitely wont pass smog chief sorry, itll pass the visual though

That’s what I’m afraid of... not passing emissions. We don’t have visual inspection here in Portland metro. But I don’t want to hassle with swapping cats every couple of years to pass emissions. [sigh].

Solo has tested them by running them in multiple cars without CELs, but getting plugged into the OBDII port might be a problem even without CELs. Still they say:

“Converters are far overrated for the car, at 6.0L per side. That’s 12.0L of cleaning ability.”

They should do the job required for emissions, but it’s a risk. They won’t pass emissions you think because they won’t filter/convert well enough you think? Or you thinking because of CELs?

My bet is just because of the CEL. Have to note, there is a mild...fuel smell everytime i start it up

Coming from a guy who does his own work, the cats are VERY easy to replace. Were talking a 4, 15 or 16mm bolts and they slip right off.

Best bet is to find a “clever” smog guy.

No way to know for sure until they test it

Well I went for it. I talked with Steve from solo via email, on Thanksgiving day no less. He answered all my questions. Relayed questions to the shop guys for me. I feel pretty confident it will work fine. No visual inspection in Portland. Plus they are having a 15% off sale this week. The high flow cats will complete my NA mods. Not sure of anything else I could do to my car after this. But there will be members who will make suggestions on how I can improve performance I’m sure!
