I was wondering for the people that swapped in a new j-pipe have you guys had any issues passing smog? I’m in Cali and I know they are pretty strict about this stuff just wondering if i’m gonna run into any issues down the line.

The cat efficiency low code can be tuned out. You need a tune for this mod.

How strict is Cali with the visual inspection?

Thanks! Cali is stupid strict! I’ve heard people have been having issues with their CVTs after getting tuned. Would you guys advised me to avoid performing this mod?

I don't know about Cali, but where I am in Eastern PA if the car is a '96 or newer (with OBDII port) they just check for codes. No code, you pass emissions. Other than Inspection considerations it's up to you, but the new Jpipe will need a custom tune which can be pricey. Every tuner I've spoken to says the CVT can barely handle the stock 2.0DIT's power / vehicle weight, but I haven't broken mine yet. I thought I did, but it looks like it was a vacuum leak and computer issue. I hope!

Go to your inspection station and tell them you're considering a custom tune and exhaust. Ask what is and isn't an issue for inspection. That's what I did.

If you don''t know what you're doing, nor that you even need a tune for this mod, then I would hold off.

Have you ever heard of data-logging? Serious question.

Stage 1, after learning how to data-log, is the first mod anyone new-to-power-mod's should go for. After you see that your engine is handling Stage 1 nicely, then you can go for more aggressive mod's.

How many tuners have you talked to? I haven't read that the HTCVT can barely handle the 2.0DIT, as-is.

There are two AWD Dyno tuning shops near me. I have used them both, and both tuners, as well as the mechanics and desk men at both shops, all state this. I am not saying it's true, just that this seems to be a "known" thing among speed shops.

Pretty much in Cali if the aftermarket part that have a carb sticker then it won’t even pass the visual test. They also have to run a full emission test on the dyno... You really can’t play in Cali 😞

Thanks for the feedback man but I already knew that I was gonna need a tune with the jpipe. I was already talking to a few tuners about it. A few of them talked me out of doing the mod but ray from turbotek said the cvt should be fine as along as you keep the torque under 300. But with everything there will always be a risk involved.

I am new to messing around with fi and tuning. But I am not mechanically inclined and know how to research before I commit to things.

if you go to a smog test place that has a 2wd dyno, all they can do is stick the sniffer probe up your tailpipe and rev the engine w/ no load on the engine (tranny in N).

all the smog places are different. some are more lenient than others. the CA DMV computers (which are connected directly to the DMV) at the smog test places can tell if the ECU was recently reset to erase emission fault codes. if they detect this recent reset, the smog tester person can tell you to drive the car around for about 30mi's to allow a retest, or they may just fail you, and the failure gets sent to the DMV and that's bad news. i'm not even sure what you would do if that sort of failure gets sent to the DMV.
