Where at in your exhaust did you use the high temp rtv? I'd have to use it right at the end of the header and I know just a few inches above that, at the O2 sensor...the header gets 650+ degrees.Get some metal gaskets & rtv sealant. I had the same leaks til I did that.
Used mine at the flanges. Is yours leaking somewhere other than that.Where at in your exhaust did you use the high temp rtv? I'd have to use it right at the end of the header and I know just a few inches above that, at the O2 sensor...the header gets 650+ degrees.
The rust could be from the outside bro. Not from under the coating, that carbon steel flange in that picture will make surface rust on the header coating, its called "Contamination".Forgot to post the rust picture...
Something is bent then. Sometimes it feels like a bigger gap than it really is too. Take a pic & post it up. Try 2 seals & rtv if its a big gap.Not even sure metal gaskets and some kind of RTV will even seal it up. My friend who was instaling that side said the gap on the top side of the header flanges was good on the bottom but the top had a gap the thickness of a nickel.

Provided the headers and exhaust he purchased are exactly the same as the factory manifolds and exhaust piping with regard to fitment angles and so on I would tend to agree but the question is, are they?This is the issue I see, you should not need to buy RTV and gaskets to fix a problem with these pipes (how much did you pay again?). They should fit perfectly, just like the $90.00 OEM replacement ones I purchased.
totally agree, I am assuming (which is not good) that he still has the stock manifold's in which case these B pipes should fit without issue for the amount of money spent.Provided the headers and exhaust he purchased are exactly the same as the factory manifolds and exhaust piping with regard to fitment angles and so on I would tend to agree but the question is, are they?
If I had a set of NISMO headers and NISMO exhaust and had a fitment issue as described, I would tend to be a bit less forgiving in my assessment of the product with regard to fitment, but when you utilize three different manufacturers for exhaust components and the manufacturers are all working with three different sets of jigs for flange angle and so on, then fitment can easily become an issue, particularly with 1/2 inch flanges.
