I have a 2wd cossie,when i bought it ,it had a stainless steel scorpion exhaust system on it but always used to blow from where it fixed to the back of the turbo,i tried taking it off a re-fitting it but it still blew so i was told it was the exhaust and to buy a mongoose system as they are a better fit.Recently i bought a second hand magnex stainless system to solve the problem but on fitting this system the blow is still occuring in the same place?my only chance left is to try a mongoose system but am worried that the same blow will happen,its as if the angle of the down pipe is slightly different to where it meets the back of the turbo?has anyone ever heard of this problem before?would you reccomend a mongoose?
