Now then, for the main culprit of my troubles...the charcoal canister.

Now I do not believe the JDM models HAVE this thing, so maybe that's playing into what's going on here. Also, KEEP IN MIND MY EXHAUST IS DIFFERENT THAN THE STANDARD R1 EXTRA. The secondary pipes (the ones I'm having issues with) have been enlarged by .5 inches to accommodate future forced induction plans. With that said, from what I see, it looks like even the regular version will have issues.

Here is the car as seen at Fontana Nissan when I took Rin in for service:

You can see the exhaust biting into the charcoal canister already. Here's a closer look at what is going on.

These pictures show pretty clearly what happened. The radiated heat from the exhaust pipes melted through a lot of it already, and the holes in the canister tripped the P0456 minor leak CEL code.

Due to the extreme hazard of driving around with this condition (this IS the fuel system we're dealing with here!), I bought a new canister and replaced it. Since we haven't figured out the whole clearance issue, we had to make do with moving the exhaust downwards to make it all fit and not melt.

The following is a bad angle, it looks like it's touching, but I have about .5 inches of space between the components.

Of course now there's black crud on the top of the exhaust piping

it will be unnoticeable when I fix it all, but for now it's pathetic.
