on a AU 6 running LPGas I got an extra 80ks out of a tank of gas.Any inprovement to an exhuast system will give better economy unless you fall it to the trap of driving it harder because the car is so much better to drive.it which case your economy will be worse
Both arent too bad. Obviously cheaper the better.
Paceys are going to bit a bit more than most headders.
If u need new cats, give herrod a ring as i think they sell s/steel headers with cats for around 1200(dont quote me on this but, and dont know if thats fitted or not). Which isnt too bad considering theyre s/steel and cats cost 2-300+ normally. Then compare to other places.
Just keep ringing round, sometimes u get better quotes from the same place on different days.
