Any of you guys heard any feedback on the upgraded muffler that Subaru sells? They day Brospeed makes it for them. It is quite reasonably priced: $375. I am considering a Cobb for my GT, as they claim to be fairly quiet when cruising. Lew Black

Thanks. I was suspicious of that. I put on a low weight pulley and Ganzflow yesterday. Big improvement in high end response and throttle response at lower rpms. Kind of noisy, though, so I am going to try some sound dampening material. I guess I am too old for the "boy racer" sound. Sure like the improvement though.
