MK 2 URD Y Pipe Emissions Question

https://www.urdusa.com/urd-mark-2-y-pipe-tacoma-2016-v6/

This Y-Pipe drops the two rear cats. Do I risk failing any Missouri Emissions?

I've already got a modified intake and a cat back exhaust. Can I expect any power or mpg gains?

 

Yes you can expect some minor power gains. Its just past the point of being noticeable but it definitely flows better. And as far as failing emissions goes I am not sure of Missouri's exact emissions laws but in Virginia where I am from we just have visual inspections only, where they raise the truck up on a lift and verify that the exhaust is connected and doesnt have holes in it and stuff. As far as they can tell, my sensors are in the right place, plugged in, and there are no simulators or anything like that plugged in, and there are no CELs so it passes emissions. FWIW it sounds great too, if you want I can post videos of my spec U full exhaust system.

Vids would be great.

 

Spec U is full exhaust sir! It comes with the Y pipe as well as the cat-back portion of the exhaust! And here it is, this video is with all 4 windows down all the way. I dont go full throttle on the takeoff but on the straight portion thats full throttle in 4th from 30-45ish so you can hear the worst drone, which isnt that bad IMO

Thank you for all that information. I'd love to hear it!

 

Do you think the readiness monitor would show some kind of deficiency without the rear cats?

 

I've already got the MBRP because it was cheap and I was curious. Hopefully the pairing doesn't set off car alarms. haha

I think your full spec U sounds great!

 

Thx for the post
That sounds really good........ I'll admit, a large portion of time is spent on YouTube exhaust note vids.
I'm in. Time to fund juggle...

 

I know what you mean man! I spent a long time listening to different videos before deciding on the Spec U! I enjoy hearing what everybody does with their trucks and how the different mods change the way the motor sounds

 

sounds sweet this is with this exact set up ?

any videos outside the truck on a cold start /rev?

also can u confirm it only removes secondary cat and still has place for 02 sensors and doesnt throw CEL

 

You will need the plug and play 02 simulator from URD when you run their y-pipe. It will keep the monitors “ready”. Because with out the cats and no 02 sim, you’ll set a check engine light and the catalyst monitor/02 monitor will stay “not ready”.

02 sim will plug into the rear 02 sensors. The front 02s are A/F sensors and do not require simulation even if you are running long tube headers

 

I do have a video somewhere but am on my phone right now and it's on my laptop, I will check later tonight. I can confirm it only deletes the secondary cats, and it does not effect emmissions control/monitoring system in any way. O2 sensors still in, no spacer or simulator needed!

 

that was the exact one you bought? not the cat back and then the y pipe? you got the whole package together and had no problems installing?

thanks for getting back to me so quick i want to order it tonight but want to make sure its right

 

Yep! That's the one with both included as a package. I know how you feel with wanting to get it ASAP! Gadget will get you taken care of bro

 

How is your MPG from before to after?

 

MPG was the same, possibly very slightly improved but is currently not comparable due to my current set of wheels and tires. Steelies and 33s without a regear is killing my mpgs.. I average around 16 city, maybe 18 hwy without wind or anything

 

sounds real good. i had the urd ypipe with a fm super 44 custom on my xrunner and it made the exhaust note sound ballistic; loved it. gonna go with a urd y again once i pick which exhaust im going with.

 

Do you have a A/T or M/T?

 

M/T! No slushbox for me
