Hi Folks I had the window down yesterday and I thought I heard the exhaust blowing so I got under the car and pressed the gas and I think it may be blowing close to the engine now I have a custom centre and back box on my Legacy but if I have to go cat back to the centre box will the car have to be re mapped or if I can get it repaired will it still have to be re mapped please advise as money is tight but I dont want to harm the engine many thanks John L.
 
depends where the leak is jj....
if you decat the system...a remap is ideally needed to prevent boost spikes!!!
just get the blow repaired is the cheapest option assuming its not a manifold or up-pipe leak!!!
