^^ That's what my catback was. Then I put the HFC in, which makes that muffler sound like butt. So I hacked it off and put a generic Bosal muffler in its place. Very loud. So I put in a resonator. Helped....
Then I decided to go turbo, so I sold the HFC, and now the catback leaks. Which makes no sense to me.
So is yours just stock? Honestly Dave, I'd recommend an STi axleback with the Stromung mid. That way, if you *do* get an HFC, it won't sound like crap like mine did. Plus, the WRX axleback is like 2.0" whereas the STi one is 2.25" like you want. If I'd known that then.... I wouldn't have any of these problems, most likely. Well, except maybe the crack.
