Hey guys, can anyone tell me if I need to drill in an extra bung to install a wideband sensor into a HKS dump pipe. Im interested in getting an air fuel ratio gauge.
The dump has 2 bungs, one before and one after the cat but I think theyre both in use already. Please correct me if im wrong.
If I do need another bung, where on the dump is the best place to put it?
