I have a cat delete kit sitting here with borla x pipe. I have not fitted it up yet(hopefully I dont have any problems too)



, but let me know what I can do to help? Measurements, etc? If you butt flanges up the passenger side is definitely longer. The passenger side flange is tighter than the drivers, but can still move it by hand. If it had anymore thickness to it, I.E coating, it probably wouldnt move. Driver side moves freely. See attached pictures. Hope this helps.

I never put the manifold flanges together like you did to compare the total lengths of the pipes. They are still in the car right now I haven't had time to take them out yet.

If I were you, I would remove your factory x pipe and test fit everything outside the car with the donut gaskets installed. If everything bolts up nice then install.

The fact that your one flange is tighter would make me want to test fit it. In the pics that you posted, are the flanges as far down as you can get them?
Mine are so tight I have to wiggle them on the pipe to move them. And they are clearly so tight that I cant get them to seat properly. I shouldn't have to use c clamps to get one thread of the bolt started.

ok but the cat delete pipes aren’t cheap. Why spend the money for them and then add headers. By the way I don’t care where you live, removing your cats voids your warranty anyway weather it’s cat delete pipes or headers.

To conclude this issue, I was correct that the pipes were indeed at fault. I bought a set of AFE pipes and they installed no issue. I sent Tony pictures of the difference in flanges and he will be refunding me my money.
As you can see in the pictures attached, the bolts on the AFE pipes stick out of the flange a lot further allowing me to connect them to the x pipe. Since I am probably one of the very few people on here that are not a vendor and have both sets of pipes on hand I will do a review on both to help others out.

I am very surprised that Norcal didn't replace the faulty pipes right away. A mistake and black mark for a business that otherwise had a great reputation. Interesting that this thread has been ignored too. Glad Norcal did refund you and that AFE pipes are working out.

i have a feeling moving forward norcal will swap out in a similar situation.

now they know their process is not bullet proof and mistakes can be made on their end.

They could at least tell a customer to ship the pipes back to norcal, and if the pipes are indeed different than the others, then norcal will refund the shipping etc, and send new pipes.

I think at this point, if i were in norcal's shoes, i would probably refund the guy on the ceramic coating also.

They obviously project perfect confidence to their customers that their pipes will fit perfectly, customer believed them, and he is out of pocket because of it. Not many instances i think a vendor is liable for aftermarket stuff like this coating fee, but if you think about it, in the end, its not worth the bad publicity. Make the customer whole, and move on.

I wonder if he went to a new supplier or hired someone on who does not know what they are doing IF he makes them himself.

Odd to go from a perfect track record to a mess up this big.

I actually haven't been refunded yet. I text him yesterday after not hearing from him since Monday night. He responded that I was right and he will be refunding me my money. That was the last I heard from him,

After selling hundreds of these pipes I'm sure he was convinced it was install error, I don't blame him. If I were him I would think the same thing also.
When we spoke yesterday through text I said, I guess I'm beat for the ceramic coating cost, he never responded to that text. Most likely because he isn't going to refund me that money.
I agree, I never in a million years thought these pipes wouldn't fit, hence why I spent money to ceramic coat them. if I were in his shoes I would refund the pipe cost and the ceramic coating cost. I've been in the car game for many years, my experiences tells me that won't happen.
