OBX center pipe

[Yaris T-Sport]

Any one has any info on this center pipe? from the pics it looks like a good fit for the 06+ hatch backs and a complete straight pipe, the dual muffler looks pretty nice.

Can you get the part number from the seller? According to OBX, they don't make that for the Yaris.

[hatchbackkid82]

I like it, price is real good too

[Yaris T-Sport]

I know that the Obx site does not show this item on their product search either, I have contacted the seller for the OBX product number and the pipe opening size, the seller replied with,

"11428 is the part number, but it should be roughly 2.25" "

which i search on the obx web site, no result found.

I'm guess 2.25"/57mm is good for force induction app, but too big for NA app. I also notice that the angle of the end of the center pipe ( where it bolts on to the tail pipe/muffler ) is not compatible with the OEM ones, as least it does not look like it in the photos. I'm guessing this center pipe will not fit the OEM or other after market tail pipe/muffler due to the angle difference at the end of this center pipe, that's why I'm guess they offer their own tail pipe/muffler to go with it, which it's a bummer.I contact the seller about this and he/she replied,

"yes the mid pipe is designed to fit the factory header system. however these were fabricated for US application and we are not sure about overseas fitments."

"the mid pipe shown here is intended to work with the rear section as shown; it will not work with the factory tail pipe."

sure enough, i was right on the money, I will go with the Nitto center pipe, because I want to keep my GReddy Ti-C exhaust

I JUST bought this plus the OBX header, will post up some pics when I install.

Overall, the quality of the header and this system looks really good, I think i might have to lengthen my 02 sensor wires though. and you can't beat the price!

[tk-421]

I'm thinking about getting this as well. I already contacted the seller and he confirms that it will fit an 07 LB.

Now I just need to know if it will fit my W*R header...

Looking forward to those pics, @computerlove87!

[computerlove87]

I think it looks like the axle back will fit the stock system, but I just looked quickly, I will be installing this weekend. My first impression of the muffler and the midpipes is that everything looks good, the muffler is VERY heavy compared to the more expensive ones like the Tanabes, but it's still slightly lighter than the stock muffler and it looks ABSOLUTELY GORGEOUS, I can't stop staring at it!!!

[hatchbackkid82]

Keep us updated and take pics, if everything goes well I may consider purchasing this. Do you have an aftermarket header?

I wish it fit sedans id be all over it.

[cali yaris]

computerlove, keep us posted, as OBX confirmed they don't make it for the Yaris and that is not a valid part number. Maybe this seller figured something out, I don't know.

[computerlove87]

Well, it looks like i'm returning the header, I opened my engine and noticed something is missing from the header.... Try to guess what :biggrin:

I will be putting on the cat-back exhaust tomorrow provided it doesn't rain.

who cares its only gonna be a cel lol

[computerlove87]

yeah but with shipping, the megan header is only $30 more, i would rather not get CEL's all the time :biggrin:

[Yaris T-Sport]

Can you take pics of the center pipe and confirm if it fits the OEM tail pipe?

Garm, when will you have the Nitto one in stock?

[cali yaris]

Shipment from Thailand is somewhere in the ocean between there and here. :thumbsup:

[computerlove87]

I started a bit too late and it got dark and I didn't want to keep trying in the dark. I am positive though that none of this system will fit with the stock system. It does seem to fit the car pretty well, but it will not work with any stock components. I will probably have to try this again next weekend or something.

How do you get the little nubs out of the rubber holders to get off the stock exhaust system? I managed to get off the muffler, but it took forever, I was wedging things in the side trying to pry them off, am I missing something?

[hatchbackkid82]

Try some WD-40 to make things easier

[schleppy]

Try some WD-40 to make things easier

WD40 + wedge a screwdriver in there = win.

Any updates? can't wait to see some pics of this center pipe.

Cool, let me know ASA they get here, I'm down.

[cali yaris]

shipment should be delivered this week. :smile:

[computerlove87]

I finally had a chance to work on this today and....Well umm this is embarrassing, I thought that a "cat-back" exhaust system meat a pipe from the catalytic converter all the way back to the end of the muffler, however, this system appears to entirely delete the catalytic converter and bolt directly on to the headers. I definitely don't want to delete my cats both from an environmental standpoint and an emissions legal standpoint, and none of this system is compatible the oem anything, so you either have to put the entire thing on or nothing on...

So, with that out of the way, I am probably going to return this system. I still have a week left before my 30 day return policy kicks in I believe so if any local bay area members want to trade me any fairly good condition axle-back exhaust for this entire system, I am up for the trade. I would ship it, but I got a 80$ estimate from the UPS store. :eek:If you have access to a lift, I am totally willing to let you bolt the thing on and try it first, I basically already bolted on part of it.

As far as pics go, If you guys who are still interested in this system want specific pics I will gladly take them, but there's not much more to see, its just a pipe that goes from the headers all the way to that GORGEOUS muffler!

The muffler is the one thing I will really miss about this system, its sooooo beautiful with those dual exits, it looks ridiculously awesome on the car!

[cali yaris]

^

none of this system is compatible the oem anything,

1. Which header does it mate with? Because the header you showed was missing the O2 bung, right?
2. Greyhound would ship that for about $35 anywhere.
3. I don't see any hangers on the axle-back section (muffler + tip). Are there hangers in the stock positions?

[hatchbackkid82]

Will this exhaust sytem bolt up to any aftermarket header or is it only their header that it will bolt up to?

Actually you were correct by thinking that... The store is the one that is wrong by stating this is a "cat-back system" when it is actually a header-back system (http://en.wikipedia.org/wiki/Exhaust_system#Header-back).

How much of a PITA would it be to modify the pipe to make it a true cat-back?

1 cut, 1 weld?

[cali yaris]

answer my questions first! me me me!

[computerlove87]

answer my questions first! me me me!

I will answer questions in the order they appear, so yes you are first LOL :biggrin:

Garm:
1. It looks like it will bolt up to the stock header, and that is what is advertised in the ebay ad, but I'm not positive because I unbolted the stock one and realized the cat-delete thing and started putting everyhting back on.
2. Cool, I will look into that then and maybe ship it!
3. it actually comes with seperate hangers that wrap around the muffler which is kind of cool because you can slightly adjust the height/how far back it is to make it fit/look perfect; however, the welds on the seperate hangers look iffy, so I was planning on bolstering them with some high tensile strength wire as a precaution so the muffler wouldn't fly off on the freeway.

tk-421 & barber:
I suppose you could cut this and weld it up to make it a true cat-back, there is nothing inside the pipe, it is basically just a pipe directly from the headers all the way back with nothin in the way until it gets to the muffler which is just a giant expansion chamber that leads to a 1 to 2 exit it seems like, none of the maze like stuff you see in a cutaway of a normal muffler (just from me trying to look inside the exhaust with a flashlight.)

Please look at this diagram I made from that bottom pic of a Yaris and tell me if I am correct:

[thebarber]

cut to the right of the resonator in your pic (yes, what you labeled IS the res). after the res you can see that the piping shrinks to 1.75" from 2"

[computerlove87]

actually, the new pipe is a bit over 2 inches, so I am going to try cutting the resonator off. I might also try to cut it in such a way that I can still use the mid-pipe back just the way they are and just cut up the pipe that was supposed to run from header to mid. That's where i wil have the advantage over the stock system because there will be no resonator or restrictive pipe diameter reduction I guess.

[thebarber]

theres not a lot of room between the 2nd cat and res to be able to cut off the resonator and rear exhaust section and still be able to easily go back to stock exhaust later...thats why i cut mine after the resonator

[computerlove87]

Yeah I think I will just go ahead and do the whole cut n' weld and make myself a custom cat-back from this thing! I guess I will do that next weekend, and record some nice sound clips and pics for people considering buying this system!

the amk header was the same. i just got a hole drilled and a bung welded. been running for months with no cel. however the collector end seems like it doesnt reach far enough so despite there being a gasket there it seems to have a slight leak. sounds cool though..

[bladesmith6]

Did you ever get this modified and installed or did you just give up ?

[Shinare]

Saw this same kit on ebay today and was wondering if anyone has installed it and what do you think? Will it go onto a stock 07 header?

[computerlove87]

Sorry I completely forgot about this thread, so I guess i should update about my experience after having this for almost 6 months now...

The kit is absolutely perfect in every way, it makes the best noise ever, it looks good under the car, the material is great, even after repeated speed-bump abuse, the car even has a noticeable increase in power, especially with my headers. There is just one problem with this kit, and unfortunately it's a big one... the muffler is just too friggin big for the car. I have spent a lot of time going back to my muffler shop and adjusting it myself and buying various length polyurethane hangers, and I just can't get the thing to stop hitting stuff back there. It sounds like i'm driving an unbalanced washing machine around, and i'm constantly trying to kick it around to get it back to a place where it stops smacking into things, but it doesn't work for long, it even hits the brake and e-brake lines occasionally which is worrying me. As a result, as soon as my next paycheck, I am getting something different.

The only way I can recommend this kit is if you want a cheap mid pipe and are planning on cutting off the muffler and getting a different one. The only problem is this kit is probably more expensive than just having some pipe mandrel bent at a shop anyway.

[tk-421]

Thanks for the review. Mind posting some pics of it installed? TIA

[computerlove87]

I will take some pics when i get it up on the lift to install the new stuff. Can't wait to get rid of the unbalanced washing machine in my trunk. LOL

[Shinare]

That doesn't sound very good then. Was it a mounting issue or a design issue with the system? Did you mate the mid pipe and exhaust with your stock headers or did you use something else? Is your car lowered or stock height? Is it banged up beyond usability or, if planning on throwing away anyway, would you be interested selling cheaply to an interested buyer? :)

Thanks!

[computerlove87]

It is not a design issue per se, it is just that the muffler is a universal muffler welded to pipe that has been bent to fit the car, the muffler is simply wayyyyy too big for the car. I am just cutting off the muffler and welding in a replacement, the piping itself is great. My setup is that I have an OBX header, then my stock cats and resonator, then the obx exhaust kit from the resonator back. I am lowered on progress in the front, cut stock springs in the back; however, no matter what suspension you have, it doesn't change the fact that the muffler is too huge for the car. The caddy has needed a new muffler for a long time, so I am going to see if I can fit this one in there :thumbsup:

[Shinare]

Thanks for the info! After talking to a friend/co-worker about what he thought about the product and he pretty much asked me a simple question. "Why don't you just go to a muffler place and have then bend you a tube from the cat back and slap a better muffler on it?" Might be cheaper and better than a full exhaust system.... I drive by a muffler place every weekday on my way home from work and never thought of that.
