I had the same problem. I had to tighten up on the lower control arm torsion bar adjustment bolts to raise the ride height of the car. This is also going to cause you to have to get the front end realigned.  

hey thanks guys but i have found the solution all be it a simple one i have put standard exhaust manifold on it which has fixed the problem and cheaply i might add thanks again for your help
