The welds look ok to me...they are MIG when I guess most of you are looking for TIG. My guess is most of the critics here really have not seen a bad MIG weld. MIG isn't pretty for sure, but these welds look pretty nice as far as MIG goes.


At any rate, my J's importer just forwarded me this message:

"Even though the welding is not a problem to Japanese customers, it is clear that many customers overseas would like to have a better appearance. Therefore, in probably 1 month, J's Racing will start a new version of C304 stainless exhaust for overseas customers. The new C304 stainless exhaust will be welded by TIG welding method for better appearance. However, at the same time TIG welding will increase the cost by about $150.00 retail. As soon as we receive a new price list, I will notify you."


Re: "There is no penetration at all. Those are guaranteed to break in a short amount of time. "

The material is probably pretty thin here...only minimal penetration is needed, and too much discoloration in the part will result in a greater HAZ resulting in broken parts.



This one is out of hand. All that heat in the part...this thing is probably so brittle...



Ease up a bit guys...I am probably as well or more versed in welding here that 90% of you at least. These welds look perfectly adequate and proper for MIG. I will say though, for the cost, Fujitsubo makes a much better looking part because of their TIG process. Look for updated product from J's shortly.

The weld on the J's exhaust flange sucks. Wayyy to fast. I'm not impressed with any of the other welds either...the exhaust is what 16gauge? That's not extremely thin. You need more penetration than that.

The above Ti part ...proper heat for a Ti weat should have a straw color to it correct? I havent done much Ti work.

I weld for a living...so I guess I fall into that 10%

 

I may have missed it but who did you order this from? the hex bolt in the muffler tip would hint to me it's there for a silencer... that doesnt come w/ the exhaust.

 

I just got the SS dual setup & my welds arent as bad as yours.
Overall im quite happy with it, but its abit loud...
The tips are tig welded & the rest is mig welded.

Should be getting my 60rs SS version in the next few weeks. Hope it is in better condition than yours vyets. Don't know if Leo could have anticipated this but thems the breaks.

 

OMFG look at the both pictures.. n look carefully at the color n the materials of the pipes...
so much different .. one must be fake..

 

dude, one has to be fake...

the one mention earlier in this thread looks like the fake ones from AJR

 

somebody email this to J's racing please..
i almost wipe my lovely j's racing name out of my mind, but after i seen this new pictures.. i finally figured one if faked...
i donno where it comes from, but i am 100% sure it's fake..

materials are just like those cheap metals that u can find at Pep Boys or Auto zones..

 

Wow, looks like a pretty noticable difference. Curious now to see what the outcome is going to be...

 

the welds on my exhaust looks great!
