Right after install the mid pipe was rubbing on the heat shield and rattled pretty loud. We jacked the G back up and removed the heat shield above the mid pipe and all is good now. The exhaust is very good quality and sounds amazing. A perfect combination of sexiness and deep tone. The car does rev a little easier now. Overall I paid $700 shipped for the Top Speed Pro 1 which was the mid pipe and rear axles and the Manzo Y pipe. I am very satisfied!!!!
