I purchased the Red Label turbo kit from these guys a while back, and it has not been an easy road. And bottom line it all comes down to craftsmanship with customer service. When I first received my manifold, it was warped. When talking to others who ran this kit, they all said theirs was also warped when arrived. RAI said they used a belt sander on them before shipping, but I doubt that happened at all. So, this equates to all of is having to spend money for a machine shop to make all the flanges flat. Quality control should have been done before it left their facility.
I have sent this manifold in twice so far for warranty repair (last one done recently). And honestly, there is no reason that I would have to wait three weeks to get it back...just to find out it was warped yet again. Now I will have to spend money at a machine shop to get the flanges milled...again. Their work is sub par.
Here is what I am taking about. Reason it was sent in was because of a sh*tty weld. If they come in to this thread to try and defend themselves, I have a welder in my shop (machinist...but does not have a milling machine) who already told me about their sh*tty job. Along with that, already had him weld small fractures that would have ended up being big cracks in no time. Then when brought to the machinist I use, he also said how sh*tty the welds are.
Reason it was sent in


Now, a correct fix would be to make a jig, cut off piece of pipe with the broken weld, grind off old weld, and weld in new piece of metal (reason for jig, to keep track of flange placement). But instead what they do it just throw a whole bunch of weld over the old weld. As stated, craftsmanship is sub par. It is just a big glob of weld. It's like these guys don't even care.


If I wanted that done, I would have just had my shop machinist do it for free and avoided downtime. But...I thought they were going to do a proper repair. So, I pay $12.xx USPS to get it there, like $40 UPS to get it back (what they used), received a bullsh*t fix, and flanges is warped to top it off. Anybody who knows, knows that the flange will warp due to the heat from welding...yet they basically didn't give a f*ck and sent it back to me without addressing it. And with the amount of glob that they call a repair (weld) which took a fair amount of heat to apply, I bet they now just compromised the other sh*tty welds on the manifold.

Used a couple of straight edge items in my house, ultimately ending using a glass from a table to confirm it is indeed wrapped...again. My advice, stay away from RAI.
Flange exactly how I sent it, with marks from my exhaust manifold basically showing they cared less...yet they of course knew it was warped (how could they not know it wouldn't warp) and sent it right back to me that way.
Not to mention the fact they will throw you under the bus and not honor their lifetime warranties. How do I know, you ask? Well, there was an issue with my manifold like a year ago. What happened is one of my cylinder head to exhaust manifolds backed out. It was one all the way at the end and on furthest corner. This left that end of the flange basically lifted up a little bit. I called them up to ask about a warranty repair. They said the repair that I wanted could not be done and I would need to pay to have a new manifold made. Yeah?????? Great customer service right. Go see my local machinist and he fixed what they said could not be done and it was quite easy (same who said how bad RAI's welds are). He basically heated the flange to make it as flat as possible, then milled it when done to save as much material as possible. Like they could not have simply taken off the flange that sits on the cylinder head and weld a new one on, but that is a whole other topic (different ways to skin a cat, yet they said it simply can't be done). Bottom line...STAY AWAY FROM RAI. If anybody else had a bad experience with them, please chime in.
