ok this is the situation, ive had my defect cleared today and had the suspension joint raise my car where the lowest point in 110mm. that point obviously being the exhaust. now ive noticed from viewing my car from the side that it has become a bloody 4WD from where i can nearly fit my fist in the gap between the guard and the tyre.

the famous s.c pettit once suggested i speak to an exhaust joint and have my exhaust attatched closer to the body of the car. it seems that the exhaust sits about 50mm or so lower that the body of the car which explains why im now driving a boat.

first off did anyone else have this problem with an aftermarket exhaust? ive got a 3" mandrel bent system turbo back. and secondly is it usually possible to attatch the exhaust closer to the body of the car? i took a quick look under the car and it looks like theres some space to do it but can it be done safely? eg without risk of the exhaust heat damaging anything under the car?

100mm within 1m of each axle from memory, exact rules are on vicroads website.

I am aiming for a bit over on the exhaust, as it all clears, but one flange fouls by 5mm, rest of the car has 130mm+ clearance.

I am seeing if I can tuck mine up a further inch, if not will look at going over the driveshafts. booked in for 8am tomorrow.

did the exhaust joint give u any idea of how much it will cost to do such a job? i cant see it being a huge job and i can image they will just changing the brackets and welding a few things

the only thing im worried about is the larger parts like the cat and the resonator not being able to fit any higher because they are pretty bulky. only way to tell is by chucking it up on the hoist i guess.

i think now that the car is raised the body sits at roughly 200mm off the ground :P

yeah i have a very very small muffler...

well i got this huge bloody cannon at the back, its quiet but its big and that might have to go. the only thing is i dont want a loud exhaust, mine is 89db on idle and 92db on 5500rpm and i still got defected for it a year ago

your pipes sound quite low in comparison to my setup. I have a second pipe that runs around/below my diff on my 33. my car is 255 in height at the rears and i got done a while back for that particular part being 90mm. the exahust place ended up heating the pipes up and bending it to sit higher which was good cause they initially wanted to do a chop job on it.

yeah i had the heat and bend done today. Have now over an INCH of clearance ABOVE legal EVERYWHERE under my car.(so closer to 140mm ground clearance pretty much everywhere) Prior to this one flange was 5mm below legal.
