Up for sale is my exhaust over $1000 new looking for $500 obo. Has a couple dents as shown in the pictures but I can't imagine it effects performance at all or minutely. This exhaust has the 2.5" coupler for the stock down pipe. I ran it with a Grimmspeed adapter with both my stock and a 3" aftermarket down pipe. http://www.importimageracing.com/jic-magic-spartan-505s-st-catback-exhaust-for-02-07-wrx-sti.html 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 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.
My car came from Hawaii so who know what kind of crazy off road adventures it had been on. I'm guilty of at least one from backing up on to a tall curb.
