Considering having complete WRX/STi TMIC pipe upgrades manufactured in polished aluminum.

BPV return pipe and couplings
throttle coupling
TMIC/compressor Y-pipe and couplings.

all mandrel bent 6061AL and wire reinforced 5/6 ply silicone couplings.

This would do away with the flex and swelling in the IC's pipe system.

Opinions are welcome.
