I'm not sure where I said they had to make it 'thicker' because it was to thin.

here is how it works...

You create a hand fabricated piece, be it from exhaust piping/aluminium/whatever. You then send it out to get replicated in casted form so the cost is lower than hand crafting it every single time. Well the casting company made it to thick on the inside which is basically choking the compressor. Thats it. Once it gets bored out to the same diameter as the prototype piece everything goes back to normal.

See..that was easy.
