Aluminium piping. Is it a mistake or not?

A FFIM on a 7M-GE may not work well. You'll loose the ACIS which helps level out the power band a significant amount and give you more power on the low end.

Yes, the metal does soak up heat quite readily. If you're doing a lot of city driving it may not be worth it. At idle my N/A's intake temps climb as much as 20?F. How quickly those temps drop once the car is moving again depends on how much I get on the throttle, but it takes a few seconds. I'm planning on adding a fiberglass sleeve to insulate it.

I really can't say I recommend removing the resonator... but to understand that you would actually have to research it and learn how it works... so do as you will.
