Having been under the car over the weekend, I've noticed the heat shield around the Cats (especially driver side) is very rusted & worn, with bits starting to fall off. Cannot afford HFC atm, so was wondering if it's worth ripping/cutting the heat shields off or replacing them with OEM cats again. There does seem to be a rattle, especially when reversing.
Just wondering if removing the heatshields will compromise them at all i.e fail MOT etc.
Any advice welcome,
Thanks,
Iwan
