[QUOTE="White_monster, post: 1319459, member: 594"] Higher grade takes higher heat. 321ss requires 347 filler rod and it's very expensive, my up pipes are 321ss that's how I know. I'd go 304ss unless you plan to run high egts all the time. 304ss doesn't take high high heat great but it is sufficient for us. If you can swing 321ss go for it but the piping is a little over double what 304ss would cost you plus the expensive filler. 316 is only a little cheaper. [/QUOTE]
