JHM V2 Race Pipes- Not so good

[FlyS4]

Ordered these a while back. Took pretty long to get here. I think the actual shipping processing is long at JHM. Anyways, at a first glance they were great!

Then I took a closer look and I saw this...
Someone took a file to it to widen the hole for more wide range fitment?

Is the misalighned pipe good for performance?


This one is just carelessness, pipe is probably going to fail or crack. Metal is cut about halfway through...

These weld gaps are found at the mounting points. Why? To accommodate for mounting nut clearance. It is this way because the pipe is wider while the flange is same size as stock.


I contacted JHM to ask what went wrong here. To make the long story short Jake stated there was nothing wrong and that’s how these come. Essentially this is what you will get if you put in the order.

As far as the return goes, I was given 1-2 weeks to see the money back and also, was denied a return shipping label for a reason that there was nothing wrong with the product. On the positive note I was told I will not be penalized a re stocking charge.

I had mine installed at JHM when they were doing my clutch so I never saw the pipes. I hope the ones they installed on my car looked better than those!

Not surprised at all.

Ya, those are terrible..... send them to me. I'll make sure they are disposed of.

Could they have hit the inside with a carbide? Maybe. Would have made a difference beyond esthetics. Not at all.
This isn't cutting diamonds.
It's a chunk of pipe for exhaust gasses to pass through. Install them.

[Dkensk]

That "cut" and "misaligned" you see is penetration from filler rod on the outside weld. The fact that flange is welded inside and out is more than alot of manufactures of exhuast products do.

There is plenty of cars with lesser quality welds and materials going faster than this platform will ever see.

But if you are still offended by these contact jhm not a forum. I'd wager most guys here have never welded.

Is it usable, I guess. Does it pass my standards, no.

Who else makes a set that's better?

Nice, didn’t know Bugatti made performance parts for a B8. Can I order it online?

Looks like A blind man welded them. Tampa auto sports are FAR superior than these piles of shit. Trust me.

I bought these awhile ago and holding off on installing them until my car goes in for the 75k service or my CATS fail. Shipping was quite quick from JHM for me, but I'm pretty sure these looks about the same. Higher quality than most, but not the best, so, I'll have them installed and see what happens.

It's crazy though, now that I see that "misaligned" pipe I'm wondering how much hp my JHM's are leaving on the table. Thanks OP...I won't be sleeping tonight.

I read this and wasn't sure if you were trying to be funny or if you are legitimately concerned...I doubt you could even measure a power drop. And I would think the O2 bung would cause much more flow "distortion" than the rough welds. But I admit, those pipes could have been cleaned up some.

I am sure for a (really, really high price) they would custom fab what you need, so just call them up.

That said, and kidding side, just like you should have called JHM first before going loud in a forum. Common courtesy dictates that you give them a chance to address your perceived issues prior to this post.

The worst thing I see on these is improper back-purging with argon. Otherwise nothing all that crazy and bad. Not state of the art welds by any means BUT probably wrong enough to outlast your car still.

Haha, look, if I make a product I would be proud of it and not afraid someone would post a picture of my work. You are making it sound like I am committing some kind of wrong doing by this. It’s all fact based, simple unboxing post.

This isn’t my first “downpipe” I have seen a lot and this is by far the worst quality. AR downpipes for the 335i was far more superior. Or any welded pipes from Forge. Aftermarket would be a better place if everyone wanted quality parts.

You can’t deny that smooth interior of the pipe would promote better flow in turn yielding better performance. Otherwise no one would get any porting and polishing in the intake side or anywhere else.

That said I would gladly pay more $ to get a state of the art pipes which are bombproof and will maximize performance. It would make me sleep better at night I have the best parts in my car that is actually an upgrade.

Lack of back purging? You meant?

Lot of heat put on the pipe at the flange, be more worried about the sloppy tig work overheating the pipe so that it becomes a fail point within a coupme thousand miles. Beyond that just looks like laziness with preppin material before proceeding with fab. Concerns about loss of HP, I think not.

Wait a minute. You admitted you never contacted JHM and just went straight to complaining on AZ.

The first JHM hears of it (apparently by way of this thread), they offer to step up and address it.

How is that my “opinion” vs. your “experience” when that is exactly what happened?

ridiculous

Even the Becker test pipes from GINA look better.

[esimp2k]

Coming from a company who does industrial welding the welding isn’t the best but that doesn’t mean it won’t last or that the end product won’t do what you want. I’d install and move on.

Welder must have gotten tired and didn't want to weld all the way around...

[bmoreS4]

I would have sent them back, no way an incomplete weld like that is ok.

I guess people like to pay good money sub-par product, not I.

Thats so your nuts will seat properly. Explains why weld inside 100%. Fabrication is def. not your background skill set.

I see your point. Nut might not fit in there properly. That looks like a design flaw. Pipe is too large in ED that won’t accommodate the nut if welded properly all the way around. Thanks for pointing it out. BTW the other side has a complete weld all the way around- so go figure...

probably still has not called Jake to take him up on his offer to make things right. so instead he keeps posting in the thread in an effort to convince the people that did not take his money and provide the product that he should get a refund or new pipes.


gofundme maybe?

Cant accomodate nut and full weld on top while also maintaining proper pipe dia for flow. Honestly 3 half inch long welds would suffice to hold that pipe on. Only reason they do the 100% from inside is so you have a sealed condition, any top weld is not necessary in this application let alone the amount that they do.

I was referring to outside weld on the other end of the pipe. Question is why do it on one side and not the other. This is the first pipe i see that is welded incomplete. I wasn’t talking about inside weld- clearly that’s to seal the pipe from gasses escaping. You are right. Half way or quarter weld of the diameter would be enough, heck even if it’s not sealed it would still work and give you a cool hissing sound. You can say you have a blow off valve :).

Be wary of criticizing JHM on this forum, your account may get banned depending on how heated the argument gets, thread locked and forgotten. This is their world (vendors that pay to keep this forum open), not yours. Understand that.
