This plate will block 100% of the exhaust gas from entering the engine.
Made from 304 stainless for long life.
Takes 10 minutes to install (& remove).
Some RG can be fully blanked; this plate is easy enough to start off with a full blank, if your engine throws a code remove the plate & drill an 8mm hole on the cross hairs.
