The ADD copy bumper turned out to be a great knockoff, I've had success with other China Headers in the past that were copies of Fabspeed, and exhaust systems. $1600 shipped to me
2inch runners, 3 inch primaries, 200 cell cats.

I don't know man, the walls on these looks awfully thin. I'm not saying china can't make quality stuff, they can if quality control and price point can be met. but that shop in the video looks janky as fuck, no uniforms, products in plastic baskets......I would cancel the order if I were you.

i know many companies here in the USA just rebrand stuff from China, my friend used to sell JDM parts his family was in the muffler business for 30 years and he did this rebranding on some exhausts he sold for many years. He only got out from what he told me because he had a few mil in profits in China that he couldn't bring back without being audited.
I suspect Fabspeed also had some china made stuff. most places in 3rd world countries operate this way, same as clothing sweat shops like Nike. My BMW titanium exhaust was from there and it was super good quality.

Ultimately for the price it is worth it, considering most of our stuff we pay 3x for come from there.

Check this out https://bcforged-na.com I ordered a set of wheels from the China factory they get their wheels made 1/2 price what they sell here, they will be in end of this month.

lol and i think the assembly line in the video is just where they wrap the heat shield. the upgrade is only $100 more at least I get hand laid heat wrapping for 1/5 the cost of ceramic and probably just as effective in trapping heat.

Interesting, keep us updated.
 
Bold move putting chinesium cats on your truck. Let me know what they smell like when they collapse and blow your engine.
How can headers blow an engine if anything it will just be free flowing from the leak
 
Oh, sweet summer child. You think exhaust only moves in one direction? Let me introduce you to a little concept called Valve Overlap and the Vacuum of Death.

Here is the physics lesson your wallet is about to learn the hard way:

1. The 'Chinesium' Meltdown Your cheap 200-cell cat isn't made of high-grade precious metals; it's made of hope and recycled soda cans. Under the heat of a supercharged Hemi, that matrix will melt and crumble like a nature valley bar in a back pocket.

2. The Blockage (Backpressure) When that cat crumbles, it doesn't just disappear. It turns into a ceramic brick, blocking the exit. Now your exhaust gas has nowhere to go.

3. The Reversion (The "Inhale") This is the part you missed. During Valve Overlap (when the intake and exhaust valves are both open for a split second to help airflow), the engine relies on the exhaust rushing out to pull fresh air in (scavenging).

BUT, because your cheap cat is clogged, high pressure builds up in the pipe. Instead of scavenging, the engine experiences Reversion. The pressure wave bounces back, carrying all that shattered ceramic dust backwards through the exhaust valve and into the cylinder.

4. The Death Spiral Congratulations! You have just introduced ceramic abrasive powder (which is harder than steel) into your combustion chamber.

  • Piston goes up: Grinds ceramic into the cylinder wall.
  • Piston goes down: Grinds it again.
  • Result: You just sandblasted your cylinder walls from the inside out. You will lose compression, start burning oil, and hear the 'tick-tick-boom' of a rod knock shortly after.
So no, it won't be 'free flowing from the leak.' It will be 'inhaling glass shards from the blockage.' Good luck with the warranty claim!

That would be a first for me if it happens. I suppose I would hear the exhaust pitch changing before it completely melts into a block plugging the exhaust exit.

Also isnt china the one with all the rare earth metals we're trying to get from greenland

Only time will tell if this works
 
The issue isn't just a full blockage that changes the tone. The issue is micro-fracturing.

When cheap ceramic substrates heat cycle (get super hot, then cool down) rapidly—which happens constantly in a TRX—they shed fine dust. You won't hear a pitch change because the exhaust is still flowing, but that dust is getting sucked back in during reversion at low RPM/idle.

You won't hear anything until you start seeing blue smoke because your cylinder walls are scored. By the time the pitch changes, it's already over.
 
Ive had high flow cats from China in two other cars and never had issues. Ill see how this goes and report back good or bad results

I'm really eager to see how the wheels turn out.
They have a couple of styles I really like and would good on my '55 T-Bird replica.

i got 4 sets of wheels from BC forged in the past for my other cars, they are the cheapest custom forged wheels I've seen available and pretty good overall. The place I'm ordering from supposedly can make any design pretty much as long as they have the dimensions, and based on the catalog I think they are really BC forge's supplier.

Look at the video they sent me as well as the final wheel that's being shipped to me as we speak, currently still in the Pacific Ocean. I had this made from BC forge's line as shown here

I completely agree that a LOT of our stuff is made in China and rebranded as American products. I am certainly interested to see how they work out for you. What differences did you notice in the bumper you got?

No difference as far as quality. I had real ADD bumpers on my previous truck and it actually chipped in several places like where welds met and began to get surface rust. This is why I decided the extra money is no difference as it is just typical machine shop welding and metal. If anything the china one was better because it is modular in assembly and I was able to adjust the frame on the skid plate myself and tighten down unlike the fixed and welded one piece ADD. Also the skid plate has the bolts welded into the plate so you dont need to hold anything on the opposite end to tighten down or worry about bolts falling on the other side.

This is like my 12th car build half of my builds I have bought parts here and there from japan to china and australia. Even my older ferrari I sourced out a used race car bumper from Poland several years back. The poor seller didnt know he had a rare or hard to find challenge series rear bumper made of fiberglass and I got it 1/4 the price what they go for with shipping.
 
Yeah I noticed over the years a lot of our stuff is just Chinese parts rebranded. Obviously you have to be smart about buying stuff from Chinese sites but as you proved its certainly possible to get good parts. Did you post pics of your bumper? I'd like to see it.
 
I mean if they work they work.....but I probably wouldn't run those cats, I've had "Chinese" Cats explode and lodge up the rest of the exhaust and cause all kinds of drivability issues that cost my self time and mental frustration of not being able to figure out what happened until I took it apart. (Not to mention what was posted above.) But Also when stainless works goes on sale you could get an American Made variant for a couple hundred more. (though as mentioned American made isn't always better).

I also am an advocate if you are planning on doing an OEM style bead lock or something of that sort instead of paying Joe Blow who middle mans from his moms living room selling XYZ FORGED Wheels, absolutely go right ahead and hit up Alibaba.
 
The place I'm ordering from supposedly can make any design pretty much as long as they have the dimensions, and based on the catalog I think they are really BC forge's supplier.
If they turn out to actually match BC Forge's quality, would you be willing to share the love and hook a man up with the contact?

I've always loved the Fikse FM5 but they're so $$ and the 2nd hand market for them has dried up.
But this looks pretty much... like an FM5 copy - https://bcforged-na.com/modular/mhe25/
