poor welds on ultimate racing hfc dp.

ho2786 · 03-30-2008, 11:01 PM

hi folks

i bought and installed the UC HFC DP on my e90 335.the welds are amatuer at best and i am worried that the welds might break when on high rpm boost and when cornering hard.

everyone with a UC DP that have weld failures ?

cheers

The welds are poor? I'm pretty sure they are machine welded...

Biturbo335i · 03-30-2008, 11:09 PM

Yeah never heard any complaints about the welding... and deff never heard of anybody with problems with them like that.

Leebro61 · 03-30-2008, 11:09 PM

Pictures of the welds? Preferably from the inside of the pipe also...

no they are human welded and they are poor.i do marine pipes for a living.
maybe exhaust pressure wont break the welds but thermal expansion and high speed cornering force may break it.

I think you should contact them directly for a partial refund or some sort other form of understanding.

they are quite good in improving throttle respond and reducing back pressure,resulting in a freer flow exhaust.i am only worried about the poor welds breaking.so far there are no reports of weld failures here.

Make this thread after you have conclusive evidence that the welds are poor...

weld failures?

simplified · 03-31-2008, 12:58 AM

seriously, pictures of the welds or I call troll.

contact UC if you're half way serious.

jcarlucci1 · 03-31-2008, 02:03 AM

Is this for real? You think a welded piece of steel is going to break from cornering too hard?

Yeah, it got my attention too. LOL, what a BS.

drphil71 · 03-31-2008, 11:02 AM

Hes not crazy in thinking that it CAN break because it moves. He just might be paranoid thats all because it most probably will never move enough.

leftcoastman · 03-31-2008, 11:06 AM

I know they have a 5-year warranty. Has anyone had problems?

In addition to ~9000 street miles, I've put 15+ track days on the UR HFC pipes with Procede v1.47 and then V2. 80 minutes a day. So that's over 1500 track miles.

No problems so far.

hotrod2448 · 03-31-2008, 12:24 PM

Pics or ban.

guys you need to realize a little sumthin' about "SOME" fabricators/TIG welders they are a bit "touched"(argon induced dementia

) and very artistic in their views. some of the VERY good ones will look down on "good" welds with disgust,distaste and loathing in some cases. On a side note if the welds do not have good penetration they can crack from heat cycles alone.

need to see some pic's to believe.

retrodrive · 03-31-2008, 12:57 PM

I heard that NOS can break welds on intale manifolds.

kptaylor · 03-31-2008, 12:59 PM

Not sure why everyone's jumping on the guy. He's a welder and he has valid arguments. DP's do fail since the motor is moving under torque and the exhaust might not move as freely. There were questions as to why no DP's had flex joints, but since everything for this car is new, we really won't know if the welds or the lack of flex joints will create problems until each aftermarket piece has had some miles and some failures.

I just got my hfc downpipes in the mail and the welds look good.
