I've ordered some flexible Nylon tubing to use with the second ViAir setup as the Poly tubing I'm using doesn't hold up in the engine bay. Is it possible to bend the Nylon to shape with a heat gun and pipe bender without weakening it?

Ok, before you guys say use the search field, I have but no one says exactly what the indy muffler shops did to get the bend out of the 06 RRS muffler tip, in order to put a straight tip on. Ive been to a couple of shops, One said that you have to buy the muffler back from a newer model in order...
