ok so i have recently installed RV6 PCD, ATLP Jpipe and test pipe and i have a greedy eve 2 cat back and a K&N CAI. so my question is, will it pass smog with just the cat back and cai and j pipe? or should i remove everything except the cat back and intake? or should i just remove everything? this i on my 2006 tl 5at with 117,xxx miles with no problems

To pass visual check: J-pipe catalytic converter is needed.
To pass smog check: Some form of catalytic converter with decent cell count is required. PCD is a no-no as it removes the pre-cats (hence the name). If you change the J-pipe ON TOP of PCDs, your car will be an angry squid on wheels.

what do u mean by "If you change the J-pipe ON TOP of PCDs, your car will be an angry squid on wheels."

i am also located in cali i know it veries on the state you are in

I'm in California.

Pardon my shitty analogy. What I meant was if you change the J-pipe and delete the pre-cats (PCDs), you will have no catalytic converter. Your car will NOT pass a sniff test, and it will smell like ass.

Either use high-flow pre-cats (HFPCs) instead of PCDs, or keep the stock j-pipe while using PCDs.

lol got confused on your 1st post, but know that u clarified it, i understand. thanks brotha. i might just go back to stock to pass the visual inspection and the sniff test to be on the safe side

Or get the HFPCD and be good on both parts.

Champ, he already has PCD's.

I'm pretty sure you won't have to go COMPLETELY back to stock. as long as you replace the PCD's and the ATLP test pipe with their stock components you'll be fine.

champ is referring to the HFPC (high flow pre cats) they are different from the PCD (precat deletes).

Ok I'll give it a try I'm going to put my stock cats and jpipe and test pipe and leave thr cat back on, has anyone had the gas cap issue? The other day, the display said to tighten the gas cap and I did and stilled keeped telling me to tighten it

If you don't have to wrry bout visuals, Just take out PCD's - then you'll pass smog. Everything else on is fine.
