URD Spec-U Exhaust, 2016+ Tacoma V6 AC/LB, DC/SB

You can't order 1/2 of a tuned exhaust system bro. Thats like saying " Ill buy half of the mona lisa"

 

I have mine half installed and discovered a problem. The right side O2 sensor bung on the Spec U is moved 1 1/2" back further than stock. This is causing the O2 sensor to hit a external transmission line on the right side. Anyone else with an A/T with the Spec U installed?
I sent UDR pictures Wednesday and some more yesterday. Waiting for a fix. I don't want to take it off and install the OEM system but I can't drive the truck with a hot exhaust part touching a transmission fluid line.

 

that pic makes me want to buy this for the clearance alone. crazy improvement and I'm not even thinking about the performance bit yet.

 

I agree, that's why I have one too.

Why not? I was telling the guy I quoted that I don't know if Gadget just did a full y-pipe re-design or if it's just different for the spec-u. And if you can buy the new design for the same price as the old one, why wouldn't you. I get that you'd want the whole system if you were all stock, but that guy had a TRD catback system, so all he really needed is the y-pipe.

The only difference between the spec-u system and ordering the urd y-pipe and catback exhaust separately, is the y-pipe design & a v-band. Other than that they are pretty much the same; same diameter piping,same muffler, both remove cats, etc. I'll concede that the new y-pipe is a much better design, and he should probably just get the full system and it would be much easier to put all together... Or just get the old Y-pipe and be done with it.

 

Thats just it, it IS different. The y pipe from the spec U and the regular Y pipe are not even CLOSE. Not only are they a different material and thickness, but the regular Y pipe is like 3 or 2.75, whereas the Spec U is 2.25. Then, for the cat-back portion, the Spec U is 2.75" straight through and sized perfectly to create adequate back pressure with the 3.5L. Other cats backs range from 2.5 to 3.5" i believe and they are all different. The URD is the ONLY exhaust available for the Tacoma that features a tuned pipe, as in flow analysis was done on the engine to calculate the diameter of pipe, as well as the material and thickness of pipe to lower resonance and allow for the best and smoothest flow possible.

Again, saying the Spec U is just like any exhaust would be like comparing the original Mona Lisa to a polaroid photo of a hot girl you saw one day. Sure, on the surface it is the same thing. But is it REALLY the same thing? Does it even accomplish the same goal? No, because it is entirely different through and through.

The URD spec-u y-pipe and their standard preforamce y-pipe are the same material and thickness. It's on their website clear as day; 2.25" 304 thick walled stainless.

Then, for the cat-back portion, the Spec U is 2.75" straight through and sized perfectly to create adequate back pressure with the 3.5L. Other cats backs range from 2.5 to 3.5" i believe and they are all different.

I agree, all other aftermarket catback exhaust systems are different sizes when compared to the URD spec-u catback exhaust portion. I never said any we're the same, better or worse. I was just comparing the two y-pipes URD had designed, apples to apples as it were.

Again, I wasn't comparing a full exhaust system to another, I was merely answering a question that a member asked, how the two y-pipes were different and if he needed the full spec-u, since he already had installed a TRD catback exhaust.

You seem to be taking personal offense to me saying the y-pipes are similar in a lot of ways.... There's no need. I already stated several times in this thread that I believe the new spec-u designed y-pipe to be a better design just for the mere fact that I like the route the driver's side takes and it looks eaiser to install.

Other than the spec-u y-pipe being routed differently, and thus making the two halfs of the y-pipe equal length. They essentially accomplish the same thing. They are made from the exact same materials, remove the rear cats, both provide better flow over stock y-pipe, etc.

I'll state this as clearly as I can to avoid any further confusion. The URD spec-u system is the best system that I currently know of on the market for the 3rd gen Tacoma.

However, this was not the question that was asked, or that I answered.

 

Hey Stevotivo12, how's your o2 sensor clearance? Did you run into the same issue as Glenn_R in post 62?

 

Mine is great, doesn't even get close to any of my stuff. If you have an MT it sounds like you should be fine but the ATs seem to have some sort of transmission fluid line that gets in the way

 

Has anyone that has installed the U- Spec exhaust had a problem with the double hanger not aligning correctly? I wasn't even able to seat one of the holders.


Initially I thought one of the pipes wasn't seated all the way, so I took the exhaust off and started over again. I made sure there weren't any burrs and made sure each piece bottomed out firmly and was in as far it would go. The other 2 out of 4 hangers align perfectly which makes it seem like the hanger was welded in the wrong spot by roughly 1 inch. It's worse than it looks in the picture, but its hard to get a picture of it without a lift. @Gadget@URD

 

If the tail pipe section can be moved a inch forward with out creating a problem with the over the axle or the rear mount I would shorten the pipe that has the V clamp on it at the muffler by 1". I didn't buy the tailpipe section so did not have the problem you are having. But when I did the install to help with the dump pipe location I cut 2" off the that pipe to move the muffler further forward.

Do you have an A/T? Did you have any issue with the right O2 sensor? Can you take a picture of the the O2 sensor that show where it is in relationship to the rubber A/T lines and how it is clocked on the pipe?

 

Yeah you shouldnt have to seat all the pipes all the way back, get it to the point t where all the mounts fit correctly and then make sure the pipes are connected enough that there's overlap where the clamps go and you should easily have an extra inch of clearance

 

With 2" cut off the V clamp pipe at the muffler this is how close the muffler is to the front hanger.

 

Ahhh ok you have a MT. Thanks for the info. I have the AT. I guess I'll see what happens when I install today.

 

Glenn_R, have you heard back from URD?

 

Yes, they are going to build a replacement front right pipe for me. I hope I can get it by Wednesday, as I want to go wheeling and camping next weekend.

 

Hmm I hope mine isn't affected as well. I am picking mine up on Monday.

 

Gadget's clears on his truck. There could be a variable in the pipe or truck that caused mine to hit. I would do that pipe first to see. Hard to tell until the new pipe and sensor is installed.

 

Sounds good, thanks. Guess I'll do it next weekend to buy myself some extra time in case of problems.

 

That's cool! Glad to hear they're making you a new pipe.

 

Great data point! Hopefully mine clears as well. Wanted to install this morning, but the wife has other plans for me today.....I guess it'll be a night install.
