Hey fellas in need of help ASAP My car is booked in for injectors, and e85 on Thursday next week at autotech but I've come across a problem.. Last week I fitted an xforce 4" dump 3.5" cat back and only drove the car if I had to (very last option) so cruising along at 60kms my exhaust seemed to get extremely louder. On further inspection I found that the bottom bolt mounting the core to the rear housing is missing and also looks to be a white line around the outside of the flange area resembling a hair line crack. Now what I need to know is 1. Is this common. 2. Would this be caused by the insufficient amount of mounts on the cheap ass xforce exhaust and 3. Why right now ? I just finished saving to get these bloody mods done.. To answer future questions the car has been tuned before to suit PW stage 2 cooler kit..always warmed up and cooled down. Never driven hard when oil temp is below a quarter .. And turbo has never been removed nor has the actuator .. I was planning to port the wastage and change actuator after tax time
