JIC Spartan 505S ST (Semi-Titanium) features our most popular style. An aggressive canister and smooth piping aid into giving your vehicle performance, a great exhaust tone, and weight savings. The Spartan canister is made of full titanium for maximum weight savings and a titanium burnt exhaust tip. Each Spartan 505S ST features a 60mm piping for smaller engines or naturally aspirated engines or a larger, 76.3mm piping for larger displacement engines and turbo applications. All spartan exhaust systems include an inner silencer. As a unique design only to the Spartan Series, the canister has either a bolt on flange or a slip in type depending on vehicle application. Certain Spartan 505S applications also has a resonated option to keep the exhaust noise down. Spartan 505S exhaust systems comes with either an angled exit or straight exit canister.
