So installed them today and took it for a drive...Super Cheap Chinese Headers = BIG A*! Smile cross my face.
Did the install on my back, not too bad. Took some time to figure how to jam the driver side header in but eventually satisfied when it locked on and bolted down. Didn't have to push engine aside like "legitstreetcar", the rest of the pipes were not too bad neither. I worked from back to front, used a rubber hammer for alignment and adjustment, clamped, extended rear O2 sensors and popped them on spacers. No CEL!!! Didn't have to turn off O2.

I got a retuned from Tony at RaceIQ for the LTH, actually I was runny the updated tune without headers install; you can feel and hear major power difference once SCC LTH install.
As for O2 sensors extension, I got both spacers from my muffler guy for $50. He gave me two wire set from an old sensor and I cut and solder them to extend, electro taped and plugged em in.
Christmas came early!!!!

Out Of Control!!
Some people will buy the cheapest thing available even with questionable business practices. Others are willing to pay a premium for a quality product and good customer service. This holds true for most products even outside of the automotive space.

Youre going to hit the same issues with most headers on the market, they're considered an "acceptable margin of error" maximizers and obx require the exact massaging in the same place (they are identical besides the flex section), a recent MBH install on an s55 required the same thing, on an sl55 midlength install we had to ding one of the runners to make it fit. for the price these fit phenomenal.

Got a CEL for O2, ECU picked it up, gonna fool it again before I shut em down. My O2 sensors is a least 10 years old, might change them out first. Car running just fine with no idle issue.

You get what you pay for ¯\_(ツ)_/¯
Yessssh G_Money, this is the best mod I have to say that I've installed/spent for the money! You can definitely feel/hear the difference and enjoy the $h1t out of your ride!
Like most long tube headers when installed, the ECU will throw a CEL for O2 sensor unless you either shut sensors off or try to trick ECU with O2 spacers; this is true for most "reputable" ones as well, so no matter how much you spend on your "reputable" LTH, you gonna get the same result (not sure if high flow cats makes a different on throwing CEL???).
I have no more CEL using spacers, so lucky! Well worth it! Will update as needed. ¯\_(ツ)_/¯

The welds look like bird poop and the stainless steel looks about as thin as a zheet of paper. I'd hate to see what the actual exhaust ports look like... But yeah definitely exactly thr same as MBH... lol they aren't even the same style .

You got me at "bird poop" and convinced me to go get the reputable LTH! Gee let's see, $2100 on MPH, plus $450 on ceramic coating, $950 on stealership install (you don't want DIY or indy shop to touch the holy grail of LTH). Hopefully for the extra money I won't get a CEL for sensors. Oh, and BUT dyno gonna feel a major difference too (in my back pocket).
Thanks G!
Thanks G!
Oh, and not to mention giving your money to support Chinese Communists for stealing designs from American or German companies? Real nice.

The welds do look like bird poop. That's irrefutable. And if you don't know how to make headers not throw a CEL you have more problems than slave-made Ebay exausts.

Thanks so much for your comments, due to your intellectual posts I have no CEL thrown, Check image below! You are amazing, I can really tell from reading your posts that you are the MAN, a righteous one no less! So caring for the global fairness and all, you should be commended! Good for you for being on top of world awareness! And here I am just thinking you just a "bird poop". But again, thanks to you my Super Cheap Stolen Chinese LTH is running fine and making as much power as the reputable ones even though it looks like "bird poop" but cost a fraction less! Good thing LTH isn't part of my hood ornament, "bird poop" and all!
Shame on me for buying stolen goods! SHAME SHAME! So naïve or stupid if you think the ChiCom is the only nation that is stealing from other nations! At least the Chinese got the ***** to steal up front unlike most of our (U.S) allies; they are doing it behind our back and lies to our faces!
p.s. sorry for any typo, spell check not working.....¯\_(ツ)_/¯
NO CEL, Christmas came early!!!
