sigh, yesterday i was driving coming back from taco bell, then all of a sudden i hear a loud BOOM, and my exhaust became like 15x louder and i hear metal clanking against each other, at first i thought it was probably a gasket blew or something, but when i got home i lifted my car and i look under and i see my s-pipe basically blew in half from the weld, so basically the welding came off and i doubt i have warranty on this thing because i bought it off someone else and idk how old it is.... heres the pix

 

sorry for the huge pix

 

DAMN!!! thats a first

 

right? thats wat i was saying, i mean im not hating on mmw or anything but just wondering why this would happen, its very expensive too ud expect it not to do that

 

i've heard of mmw headers busting at the welds... not the s-pipe though. maybe you rocked your engine super hard lol. hope it never happens to me though..

 

Nope u just got a bad unit -- I would call Weapon-R and ask for Chris W. (I think he's still there) Send them the pics and ask for a replacement. And in the future stay away from Weapon-R.

 

yea i already pmed, him im gonna see what we can do

 

please keep us updated on this.

 

Why is there even a weld on the S pipe? Other Spipes dont have a cut there.

 

i believe the s-pipe is welded at where the pipe bends or angles.

 

i have an mmw s-pipe right here, there are four welds, 2 at each bend. i guess instead of making a mandrel bent s-pipe, they just weled together straight and elbowed pieces.

 

Yeah i know, that is very disapointing to me, For such an expensive header, they cant even make the s pipe mandrel bent. Besides having a chance of this kind of failure. Would this lead to less performance gains? Since mandrel is always more smooth.

 

ok i just got my s-pipe done and rewelded so i guess im good to go but i still notified weapon r about this

 

Good and please ask them why they cant just make the S-pipe mandrel..

 

yea i will as soon as they reply back to my message which so far no answer

 

Lol aww thats terrible. Alot of people hate weapon-r and their customer service. For some reason i still bought there product. Hey do also have an aftermarket exhaust? I was wondering if you are running rich. As in burning too much gas. My mileage is terrible now compared to stock. Also how does your car drive with the MMW header? Still smooth?

 

yea i have a megan drift spec exhaust, its not too rich i have a gauge tellin me its normal so its not too bad and the header added a little vibrations but thats because when i was under the car i saw the spipe is basically touching the frame of the car so it has a bit of vibrations, im gonna have to wrap that sucker up

 

I think the reason it may of happend is because the way it is designed where the header meets the s-pipe. Unlike the stock set up it doesn't allow the exhaust to flex and puts all the stress on the exhaust pipes. The pressure when you got on it probably blew the weld. Im thinking about having them weld a flex pipe on to it when I get the new exhaust.

 

I still wonder why they couldnt make it mandrel bent like other companies. Also so far they havnt responded to my email either.

 

mandrel's costs more money probably. if they made this header any pricier, i'm sure they would've gone bankrupt.
