JoeZ Full Exhaust and California Smog
I'm looking to update to JoeZ Full Exhaust system on my 2015 GS 350 F Sport RWD.
Does anyone know if this exhaust will give me problems when doing Smog Check?
I live in Southern California, one of the toughest smog emission part of the country.
I don't want any headaches with Smog if I do any aftermarket mods to exhaust system.
Don't want to swap stock parts neither to do smog. I might as well just stay stock if that's the case.
Also, I see some people doing invidia mid pipe with joez axle back. What are the benefit of this vs Full JoeZ exhaust?

Would also like some insight to the same question. Looking to purchase JoeZ catback but worried that it won't pass smog and would have to switch to stock to pass.
@jdpdata, where would you purchase your exhaust if you were to go through with it?

Oh, I was under the impression that catback=full exhaust....is that not correct? If not, what does the full exhaust consist of?

Post 2000 cars use the new system. The DAD connects to the car's OBDII system. No dyno or exhaust sniff. If the cats are gone then it may fail visual (provided they visually check it but it will most likely set a light anyways). If the cats are swapped to aftermarket units then they will need to have the proper E.O. number for the year they were replaced (again, provided they do the visual inspection). If it is a cat back system then it won't affect anything.
*Joe Z's full system looks to be cat back so you shouldn't have any issues with smog.

Off road is from the exhaust manifold back, cat back starts behind the cats, and axle back is just the rear muffler and tip section.

cat back or axle back systems will not have any affect on your smog test.
a full exhaust will probably not have any affect on the test as long as you don't have any errors from the oxygen sensors. However depending on the shop they could ding you on the visual exam.
I have a full exhaust, long tube headers, hi-flow cats, etc. on my 4runner, it smogged well within spec without issue, and the shop owner knows me so he "over-looked" the visual, but did warn me another shop would not.
