Because the pipe was put through the wheel arch instead of under the floor pan where most people run it after it leaves the side pipe it tucks away nicely from memory the exhaust is not lower than the floor wich is a good thing , The rear muffler is visible from the drivers side of the car if you squat down a bit but the fuel tank is lower than it anyway . BUt after rego it wont be there anyway
I like your pipes cause you can see the 4 into 1 on the outside of the car , does yours need an oxygen sensor and if so where are you putting it . Thats the main reason i put mine into a collector before it exited the body as i didnt want the sensor hanging under the car in plain sight
