godzilla dyno'd after installation of BBI exhaust. unfortunately the cobb access port we received was not working properly so the hp increase potential was neutralized by the stock ecu. however the exhaust did show a massive initial increase in low end torque (almost 50 lb/ft) at 2100 rpms, which indicates that this 3.5 inch stainless exhaust is going to yield great results after the ecu tune is downloaded. nevertheless, we were all impressed by the sound of the exhaust.
