- It is inadvisable to use any exhaust sealing paste upstream from a catalytic converter or diesel particulate filter. If excess paste breaks loose it can irreparably damage the substrate. Normally warranties will not be entertained if this is found to be the case
- Joints designed to flex such as olives, flares etc. should not use any paste, we advise a new fitting kit is used in all instances
- Exhaust paste can contaminate oxygen, temperature and NOx sensors
- Exhaust paste can block the pores of a DPF; the particles of paste cannot be incinerated during regeneration
