No, those discs are normally junk. The block off plug, EGR Cooler exhaust, is the only one we use, it is a very beefy machined chunk of stainless steel. Mr Hagg has them. Everything else on the motor is left alone, no plates or removing anything. Mandate is taken care of with the computer, and of course the cans... Call Mr Hagg and make an appointment. Just make sure the motor is healthy, open the top and inspect the cam shaft and lobes for starters. If the cam or rollers are chewed up, you are going to need work prior to eliminating any mandates.

The reason those kits are junk, is that the stainless steel is suspect, and thin. The exhaust gases quickly destroy these inferior parts. The plugs we use are roughly an inch and half deep, made out of quality, I forget the number, American Made stainless.
