at least I think its the dump pipe. got a hole about the size of a 50c piece on underside of exhaust pipe ( at the curve ) bout half way between flexi and where it bolts onto turbo.factory exhaust. Theres no noticeable noise or power loss that i can tell simply because this hole looks to have been there since the day i bought her 9 months ago so nothing to compare it too,I pulled a bit of the heat shield back and there it was.
am I missing out on a couple extra kw's or km/l because of a hole of this nature ?

It will be rust in the outer heat shield. The firbreglass **** underneath it (between heatshield and actual exhaust pipe) get moisture in it and rusts the heat shield from the inside out.

Its an excuse to get a 3" pipe ;)
