Weapon R Header Broke

[Malaya1221]

:mad:

[Black Yaris]

this mostly happened due to the spherical joint being removed when an aftermarket header is installed.... My exhaust guy fixed this for me by adding a new one so their will be some flex

[cleong]

Seems like the header's flange didn't meet the midpipe's flange well enough and was "pulled" into meeting up and screwed up. Eventually the repeated heating caused metal fatigue that sheared the header's tube at a weak point.

[PetersRedYaris]

I thought Weapon R was a descent brand?

[Malaya1221]

holy crap, sorry to hear that malaya :eek: looks like the weld right before sensor bung failed?

not sure yet where it failed kuro, haven't taken out the header yet....from what we could c u r correct, it seems like it broke from the o2 sensor but will take another pic once it's out!

[kou]

yes, it's split in half by the o2 sensor!:mad:

calling WEAPON R....i need warranty on this!

hey garm, still thinking about the DC header that you got.....might just install the oem header!

that wouldnt have happened if you had the springs on those bolts.:thumbsup:

[TEHxFALLEN V1.2]

Oh man, that doesn't look good at all!

[largeorangefont]

that wouldnt have happened if you had the springs on those bolts.:thumbsup:


Absolutely. That failed for two reasons, install error, and inferior fit.

Get a DC.

[kou]

the only problem with fit is the pipe needs to cut down where they meet if cut prior to install it is fine. that nitto pipe looks to small.

[PETERPOOP]

everyone knows weapon R sucks

[Sabretooth]

First intakes that get "8hp" gains...now cracked headers...not looking good for them.

[Astroman]

Yet another reason I'm glad I got a DC header.

[Sabretooth]

Hell even nobody is having issues with the Megan Headers....and everyone thought that was going to be the first to give problems.

[eco]

Megan header here,NP.And it was from the GB way back then.

[saplaymate]

That wasn't the headers failure, thats all from modifying way the pipe mounts!

yes in general weapon does suck

[llimonce]

you need the springs.. men .. because without the springs , the torque broke the header ..

the springs are a torque absorber .. be carefull

[Malaya1221]

with this particular setup, i don't get the spring issue...maybe someone could enlighten me...:smile:

[AznGouki]

Crossing Weapon R off my list and adding DC

[ROCKLAND TOYOTA]

:laugh: funny hearing all the THEY SUCK talk. maybe if installer had used proper hardware this would never had happened....

[ChinoCharles]

Does the Weapon install guide call for using those springs? Did they even send one?

Come to think of it I don't think I've got mine on... hmmmmm.

[ROCKLAND TOYOTA]

^^ KOU and i had this discussion this afternoon. it needs the springs...........

[ChinoCharles]

I have to change my oil tomorrow anyway. Dammit, I was so ready to be done with the big ratchet...

[PHXDEMON]

Like all the previous have said, this probably would not have happened if it was properly installed.

[ROCKLAND TOYOTA]

what so different about this setup????

[ChinoCharles]

Without the springs, it isn't like the play between the header and center pipe is gone. It is still there, just without the constant push outward. I'm kind of confused myself to be honest.

[Thej3sta2]

I just want to here how the damn thing sounds like that Loud As F___ im guessing

[kou]

the springs are to hold the pipe against the header so when the motor move's it is not trying to pick up and put down the entire exhaust system,there is movement in every direction with the springs. without springs the torquing back and forth will fatigue the metal and crack.dont blame the manufacture for your own mistakes. i have been using this for over a year and it still looks as good as the day i got it.

[ROCKLAND TOYOTA]

over a year and been on 2 yari........

[ChinoCharles]

Thanks for the clarification kou.

[kou]

your welcome, just want to make sure that everyone knows that this can happen to any header overtime without the springs,toyota put them there for a reason.

got it and i'm glad that yours is still in good condition!:thumbsup:

it looks like u r an expert on this, so is it fair to ask that when fabricating a header back exhaust or turbo exhaust, the weld will not hold because of the vibrations, movements and weight of the entire exhaust system unless a spring bolt is used to bolt them on?

[eco]

Another reason to buy a torque damper for the engine.

header back exhaust should always have some kind of flex joint so that the is some play.turbo is another story as alot of the manifolds are shorter and cast pieces with extra support brackets for the weight of the turbo and down pipe but after that there should be a flex joint.

[Malaya1221]

thanks kou.

[Malaya1221]

what so different about this setup????

have the nitto mid-pipe with the weapon r and while installing it using the oem bolt spring, the screw was all the way to the end of the treads but it still had a gap(fit was not snug) so comes the air leak!

can we get a video clip of this thing at WOT from inside the car?

[Malaya1221]

^ IT IS LOUD!:biggrin:

if u close ur eyes u wouldn't believe it's the yaris!

on idle, bog bog bog bog!:tongue:

[White Yaris]

that sucks... Hey you had fun with it right?

[Malaya1221]

^ absolutely! i like the 4-2-1 type header but the weld on the o2 sensor where it broke had rust on them...IMO, the weld on the last tube was not primo!

got me a dc header (4-1) from garm for a very reasonable price!:biggrin:

[ztrack157]

I have thought about this over the last few weeks and I have the answer to why this happened. There is a flaw in Weapons design of the header that Megan and Toyota didn't have. Do you remember the side bolt that was on the bottom of the stock exhaust? That is for this very sort of occurence. It prevents the exhaust from rattling around and reduces vibrations. This is why I haven't had a problem with my megan. Other people who have other headers maybe even the Weapon itself might not have the same issue as you did. But not having that extra anchoring point is likely the culprit.

[kou]

read the entire thread the reason has already been found.

[ztrack157]

Just because your theory on what happened is accepted doesn't mean it was the only factor. I'm just offering more into what caused the malfunction. Theres a bunch of things wrong with this set up.

[kou]

how, it bolts on the same way.if you dont put the springs back on the bolts like it is stock any header will snap with fatigue.

[Malaya1221]

no need to argue boys, weapon r gave me a warranty on this!:wink:

yup, only weapon r header doesn't have a side bolt!

[kou]

nice of them to do that.

[Malaya1221]

yup, they decided it was their fault and i'm one happy customer!

[bobobitch]

so do you know if weapon r is going to fix that problem?

[ztrack157]

They should for future models.

[kou]

i suppose it could be a problem but i have had know issues for 2 years and 2 cars. the point is you need the springs, they have to be there..

[Malaya1221]

imo, kou has a point here in installing the spring bolt because it would help lessen the vibration but, to say that's the answer to the problem w/o knowing all the factors would be foolish...

i think we should ask someone who has the nitto mid-pipe and weapon r header installed in their car and give us their opinions about it because mine did not fit snugly while installing it with the oem spring bolt!

i think weapon r header has it only for less than 2 yrs so i wouldn't know where kou got his 2 headers!...

[kou]

its been on 2 different yaris.

[cee_dub2003]

that wouldnt have happened if you had the springs on those bolts.:thumbsup:

This is Chris W. from Weapon-R. I was reading this post and cant seem to see pictures anymore. But by reading the thread there was! No springs on the bolts?
I don't think there was mention in your email with the pictures that the springs bolts were not installed. Without those springs it will create a bit of stress on the flange. We have taken care of this customer. But for further reference this was a improper installation and we would have not warrantied the header fully.

[id3379]

everyone knows weapon R sucks

+1

[id3379]

yup, they decided it was their fault and i'm one happy customer!

wow, that's awesome customer support coming from weapon r... good for them.

[bobobitch]

does anyone have a picture of the spring bolt you are talking about??? and also you dont need to get a mid pipe as soon as you install the header right i thought you could use oem for a little while
