DTLT and rear o2 sims

will i pass smog with the rear o2 sims in place? im going to still keep my stock y-pipe and 2 cats. but i want to know if i go to do an emissions test, if i will pass or not?

 

even if i keep 2 of the 4 cats. do they people know that they have 4 cats now a days?

 

*IF* is they key. so im just basically taking a risk.

 

shorties and a y pipe would pretty much be a risk too?

ugh, so many decisions. just worried with shorties i wont feel enough of a gain...

current mods, Airaid CAI, with TRD cat back

 

well it had the exhaust on it already and i just installed the intake. minimal gains, but i did feel a slight more power. im looking to gain the most power but stay N/A

 

lol yea, been doing a lot of youtube-ing. blowers are def bad ass. just pricey when in order to keep my warranty, i have to do it at the stealership

 

i know that but its like close to $4,000. and i just bought this truck. dropping another 4k in it, gives me a blah side about it haha. but thanks for the info. i dont think ill mess with the cats then. (just read it gets LOUD if cats are removed) and i dont like rasp.

 

I understand thr tubes also create a lot of extra heat. Were you going to spray them with a heat resistant coating?

 

You can always do like i did on my girl's truck. We installed JBA shorties. Had V-band flanges added to them, so that we could easily swap the cats out for "test pipes". It will cost you more, but will give you mkre flexibility as well.

 

Spraying them with coating or wrapping them will void your warranty with Doug Thorley.

 

They are already coated from Doug Thorley themselves. Might not be the best ceramic coating, but still coated.

 

or just live in a county that doesn't have emissions testing like me. I have a 2012 and im running DTLH URD 4x4 y-pipe, and URD/Magnaflow 3 inch exhaust. Waiting for aFe/TRD intake.

Or just have your truck registered in one that doesn't have it. Easy as that.
