Well to give you an indication mine run a 13.1 and its a fuckload heavier then yours so you should do a fair bit better then mid 13s. You might need to pay for a decent tune though the oztrack mail orders are alright but arent very aggressive overly safe so yea mid 13s lol. Also i drove mine day in day out in traffic with an auto thrashing it and the economy sat in the 14s low 15s which i think is decent for the driving it almost never saw open road. Better then my xr6t ute stock.
I fiddled with a hsv exhaust/extractors back in my vy ls1 they arent much chop to be honest the exhaust still has plenty of bits that are squished/flattened i dunno what for maybe epa or noise requirements. I dunno i reckon my vy sounded nasty but i guess depends on the setup mine had the rear muffler missing so it sounded weird. Look out for a 2nd hand 2.5" difillipo cat back make sure it has all the mufflers you wont be disapointed thats how i bought mine it wasnt overly loud at all. You will find if you go big 4 into 1 extractors is what makes all the noise.
