I ended up putting the cat back in as it helped control boost. I just put it out every few months and check it out.

Might be over boosting but then again, plugs are just copper v-groove and are a bit old as well as the coil packs which have seen over 6 months so might be time for some fresh ones. I'm keeping off it anyway until I do get it looked at.I heard XForce changed their CAT design at some point to remedy this issue. Apparently the substrate was in it's own case then that case was welded to the CAT body? My system is over 2 years old so probably an older one.

It was only a fluke that we found it when we unbolted it to try and get it to stop banging underneith.

Have to say, the rest of the system is still in good shape. Week link seems to be the CAT and fitment.

The one on my car is still going well from what I can see Link to comment https://www.fordxr6turbo.com/forum/topic/55751-xforce-exhaust-thread/page/56/#findComment-1030421 Share on other sites More sharing options...

Also if you gut or simply change to a higher flowing cat then get the tune checked asap or you're asking for trouble. If the tune uses closed loop boost control then it's not so bad but for those with tunes using an open loop strategy (90% of you) then for heaven's sake stay off boost!
