So I have done the above, I have gutted the cat removed the mid box and back box, and still she doesn't sound that different. I can here the turbo a tad under load and that's it. When I had the rear pipe work removed it sounded awsome just what I wanted a deeper tone and you could really here the turbo spooling. As soon as I put the rear pipe work back on, could here sod all, any ideas?
