Default WRX harness through the firewall on an RS swap

I know several of you have already done swaps as have I but all the swaps I've done so far I've used the stock downpipe. My concern is that when upgraded to a aftermarket DP at a later date it is gonna be really realy close to the harness. What has everyone else done to combat this issue?

Any input would be appreciated and photos would be even nicer.

You happen to have a pic of your stock downpipe in your car and a pic of the stock downpipe in a WRX?

Also, the stock downpipe is fairly large and gangly. It might be that an aftermarket downpipe requires no additional room.

Junkyards are fun!


aftermarket downpipe is actually much less room taking. oem has giant cats and heatshields and the like. perhaps wrap the harness in the aluminum foil type heat shielding like the PS lines have

I looped my harness "OVER" the AC line....that way it has some extra clearance to combat the heat...Plus I put heat shielding over the harness to help also...then Electrical tape...then loom...
