Available in both 7" and 8" sizes. The Smeding Diesel Cat Stacks are manufactured with rust resistant 409 stainless steel and powered coated with a high heat semi flat black finish for that rugged industrial look. Overall heights are 38" tall for the 7" diameter and 39" tall for the 8" diameter. Both Smeding Diesel Cat Stacks have a large 5" inside diameter inlet at the base for easy installation with readily available installation kits. Ben Smeding Jr. owner of Smeding Diesel says he noticed truck enthusiasts who had stacks built out of standard steel quickly had rusting problems. This is from the high EGT's of many performance tuned trucks. Knowing this, Ben Smeding Jr. decided to build all his stacks from 304 stainless steel for the polished stacks and 409 stainless steel for the high heat powder coated stacks.
