can i decat without any issues?

[Palmer]

S8 has developed a rattle over the last few days. It went on a long run yesterday (100+ miles) and the car was so loud when i got back (didnt really notice with the windows up, another point for build quality!)

Had a look under and the exhaust has come off at the cat. I can see the bolts on the downpipe are loose which was the rattle.

Im going to get my floor ramps out tomorrow and have a look underneath. If i cant save it and have to get it repaired, can i take the cat out without any issues? I.e engine lights on the dash etc.

Must admit it pulled really hard yesterday with in essence just a downpipe, and sounded the dogs danglies. Really tempted for a full exhaust now ha
