Installed XO2 exhaust (HKS Clone)

EDIT: Added pics below.
Pepepr and anyone else who's installed this exhaust, did you have any exhaust leaks? I installed this on my G35 last Sunday and had some major exhaust leaks at 3 of the flanges (at both ends of the extension pipes, and the driver side muffler connection). I got back under there today and loosened it all up and attempted to fix it, but it's now worse than before
I noticed that the flanges on my extension pipes are completely out of wack. I laid them flat on the ground flange side down, and one of the flanges was not flat, it was angled more than all of the others. I tried installing the pipes every possible way, and there's no way this thing will ever seal properly.

my extensions had the EXACT same problem. I had some extra paper/metal-like gaskets & just doubled up on the gasket on the drivers side, no more leak for me. You could just buy an extra gasket, trim it and install...
ps: otherwise I'm VERY happy with the exhaust, sounds great, pretty good quality. Gets a 9/10 from me!

UPDATE: I contacted Invision Performance and they're gonna send me a new set of extensions.
FYI, I tried arranging the pipes in every way possible, and there is no way this thing will ever seal properly. The one flange is just short, and the angle is off. Even if I doubled the gaskets here, when I tighten it all down it will just pull apart the flange at the other end.
If the new ones come in with the same problem, I'm just gonna have a machinist shave them down so they are even.

Pepepr you will realize in a year or two why this "XO2" exhaust is $1000 cheaper than HKS.
You will realize it when the sound and the condition of your exhaust change as time goes on.
You want to know the difference? Go look into the metal grade of their exhausts and you will know, the amount of corrosion protection among a lot of other characteristics of various metal grades varies.
1 of the main thing i can tell you is the 'Alloying' content, when adding small amount of different metals (ex: Cr, Chromium) into Stainless Steel, (In this case, I believe that Exhaust systems usually use Ferritic Stainless Steels) the pricing of the overall product will greatly increases, of course it also have to do with how much alloying you are doing to the system.
Without going further into any detail, you GET what you PAY for. You really think a company would make the same quality exhaust as another company, but only to sell it for less than 1/2 the price of them? I am giving you some of the 'actual technical metallurgy information' regarding this matter.

I agree with everything IchiBahn says about the quality of the metalurgy, this is usually the difference between vender parts but does anyone have the actual content of the HKS vs the XO2 exhausts? Without a factual comparison of the compositions this is still just a theoretical discussion. Could they be the same composition? Doubtful. Is there a premium applies to the HKS system because of the name, Probably. I would say HKS has built in their RD and that is where part of the $1000.00 difference lies.

hey jacka$$... i didnt call you a name until now for a reason.... theres no need for name calling. i didnt buy the exhaust cuz it was an HKS replica. I bought it because it was a cheap mod and if i didnt like it, i could unload it easily. i dont care if i gained 1hp or 20hp. i like the way it sounds and thats all i wanted. i dont get why people like you have to chime in and rain on peoples parade. there have been a few threads that have been hijacked by the haters. give it up man... no one cares.
have a nice day.
